The function `git_repository_head_for_worktree` currently uses `git_reference__read_head` to directly read a given worktree's HEAD from the filesystem. This is broken in case the repository uses a different refdb implementation than the filesystem-based one, so let's instead open the worktree as a real repository and use `git_reference_lookup`. This also fixes the case where the worktree's HEAD is not a symref, but a detached HEAD, which would have resulted in an error previously.

The function `git_repository_foreach_head` is broken, as it directly interacts with the on-disk representation of the reference database, thus assuming that no other refdb is used for the given repository. As this is an internal function only and all users have been replaced, let's remove this function.

Given a Git repository, it's non-trivial to iterate over all worktrees that are associated with it, including the "main" repository. This commit adds a new internal function `git_repository_foreach_worktree` that does this for us.

When compiling libgit2 with -DDEPRECATE_HARD, we add a preprocessor definition `GIT_DEPRECATE_HARD` which causes the "git2/deprecated.h" header to be empty. As a result, no function declarations are made available to callers, but the implementations are still available to link against. This has the problem that function declarations also aren't visible to the implementations, meaning that the symbol's visibility will not be set up correctly. As a result, the resulting library may not expose those deprecated symbols at all on some platforms and thus cause linking errors. Fix the issue by conditionally compiling deprecated functions, only. While it becomes impossible to link against such a library in case one uses deprecated functions, distributors of libgit2 aren't expected to pass -DDEPRECATE_HARD anyway. Instead, users of libgit2 should manually define GIT_DEPRECATE_HARD to hide deprecated functions. Using "real" hard deprecation still makes sense in the context of CI to test we don't use deprecated symbols ourselves and in case a dependant uses libgit2 in a vendored way and knows it won't ever use any of the deprecated symbols anyway.

We _dispose_ the contents of objects; we _free_ objects (and their contents). Update `git_strarray_free` to be `git_strarray_dispose`. `git_strarray_free` remains as a deprecated proxy function.

Git has supported repository format version 1 for some time. This format is just like version 0, but it supports extensions. Implementations must reject extensions that they don't support. Add support for this format version and reject any extensions but extensions.noop, which is the only extension we currently support. While we're at it, also clean up an error message.

When checking whether a path is a valid repository path, we try to read the "commondir" link file. In the process, we neither confirm that constructing the file's path succeeded nor do we verify that reading the file succeeded, which might cause us to verify repositories on an empty or bogus path later on. Fix this by checking return values. As the function to verify repos doesn't currently support returning errors, this commit also refactors the function to return an error code, passing validity of the repo via an out parameter instead, and adjusts all existing callers.

The flag GIT_FILEBUF_FORCE currently does two things: 1. It will cause the filebuf to create non-existing leading directories for the file that is about to be written. 2. It will forcibly remove any pre-existing locks. While most call sites actually do want (1), they do not want to remove pre-existing locks, as that renders the locking mechanisms effectively useless. Introduce a new flag `GIT_FILEBUF_CREATE_LEADING_DIRS` to separate both behaviours cleanly from each other and convert callers to use it instead of `GIT_FILEBUF_FORCE` to have them honor locked files correctly. As this conversion removes all current users of `GIT_FILEBUF_FORCE`, this commit removes the flag altogether.

When initializing a repository, we need to check whether its working directory supports symlinks to correctly set the initial value of the "core.symlinks" config variable. The code to check the filesystem is reusable in other parts of our codebase, like for example in our tests to determine whether certain tests can be expected to succeed or not. Extract the code into a new function `git_path_supports_symlinks` to avoid duplicate implementations. Remove a duplicate implementation in the repo test helper code.

Our file utils functions all have a "futils" prefix, e.g. `git_futils_touch`. One would thus naturally guess that their definitions and implementation would live in files "futils.h" and "futils.c", respectively, but in fact they live in "fileops.h". Rename the files to match expectations.

When using templates to initialize a git repository, then git-init(1) will copy over all contents of the template directory. These will be preferred over the default ones created by git-init(1). While we mostly do the same, there is the exception of "HEAD". While we do copy over the template's HEAD file, afterwards we'll immediately re-initialize its contents with either the default "ref: refs/origin/master" or the init option's `initial_head` field. Let's fix the inconsistency with upstream git-init(1) by not overwriting the template HEAD, but only if the user hasn't set `opts.initial_head`. If the `initial_head` field has been supplied, we should use that indifferent from whether the template contained a HEAD file or not. Add tests to verify we correctly use the template directory's HEAD file and that `initial_head` overrides the template.

Update `git_repository_init_ext` to use our typical style of error handling. The function had multiple statements which didn't `goto out` immediately but instead deferred it to later calls combined with `if` statements.
Patrick Steinhardt committed -
The error handling in `git_repository_create_head` completely swallows all error codes. While probably not too much of a problem, this also violates our usual coding style. Refactor the code to use a local `error` variable with the typical `goto out` statements.

For example, https://git-scm.com/docs/gitrepository-layout says: info Additional information about the repository is recorded in this directory. This directory is ignored if $GIT_COMMON_DIR is set and "$GIT_COMMON_DIR/info" will be used instead. So when looking for `info/attributes`, we need to check the commondir first, or fallback to "our" `info/attributes`.

In libgit2 nomenclature, when we need to verb a direct object, we name a function `git_directobject_verb`. Thus, if we need to init an options structure named `git_foo_options`, then the name of the function that does that should be `git_foo_options_init`. The previous names of `git_foo_init_options` is close - it _sounds_ as if it's initializing the options of a `foo`, but in fact `git_foo_options` is its own noun that should be respected. Deprecate the old names; they'll now call directly to the new ones.

Functions that free a structure's contents but not the structure itself shall be named `dispose` in the libgit2 project, but the function `git_cache_free` does not follow this naming pattern. Fix this by renaming it to `git_cache_dispose` and adjusting all callers to make use of the new name.

Currently, the lifecycle functions for maps (allocation, deallocation, resize) are not named in a uniform way and do not have a uniform function signature. Rename the functions to fix that, and stick to libgit2's naming scheme of saying `git_foo_new`. This results in the following new interface for allocation: - `int git_<t>map_new(git_<t>map **out)` to allocate a new map, returning an error code if we ran out of memory - `void git_<t>map_free(git_<t>map *map)` to free a map - `void git_<t>map_clear(git<t>map *map)` to remove all entries from a map This commit also fixes all existing callers.

Right now, the function `git_repository_foreach_head` will always iterate over all HEADs of the main repository and its worktrees. In some cases, it might be required to skip either of those, though. Add a flag in preparation for the following commit that enables this behaviour.

Teach `load_config` how to load all the configurations except (optionally) the repository configuration. This allows the new repository codepath to load the global/xdg/system configuration paths so that they can be inspected during repository initialization.

Emulate the Git for Windows `core.symlinks` support. Since symbolic links are generally enabled for Administrator (and _may_ be enabled due to enabling Developer mode) but symbolic links are still sufficiently uncommon on Windows that Git users are expected to explicitly opt-in to symbolic links by enabling `core.symlinks=true` in a global (or xdg or system) configuration. When `core.symlinks=true` is set globally _and_ symbolic links support is detected then new repositories created will not have a `core.symlinks` set. If `core.symlinks` is _not_ set then no detection will be performed, and `core.symlinks=false` will be set in the repository configuration.

We were previously conflating any error into GIT_ENOTFOUND, which might or might not be correct. This fixes the code so a config error is bubbled up, as well as preserving the semantics in the face of worktree-repositories

Strict aliasing rules dictate that for most data types, you are not allowed to cast them to another data type and then access the casted pointers. While this works just fine for most compilers, technically we end up in undefined behaviour when we hurt that rule. Our current refcounting code makes heavy use of casting and thus violates that rule. While we didn't have any problems with that code, Travis started spitting out a lot of warnings due to a change in their toolchain. In the refcounting case, the code is also easy to fix: as all refcounting-statements are actually macros, we can just access the `rc` field directly instead of casting. There are two outliers in our code where that doesn't work. Both the `git_diff` and `git_patch` structures have specializations for generated and parsed diffs/patches, which directly inherit from them. Because of that, the refcounting code is only part of the base structure and not of the children themselves. We can help that by instead passing their base into `GIT_REFCOUNT_INC`, though.

Our current configuration logic is completely oblivious of any repository, but only cares for actual file paths. Unfortunately, we are forced to break this assumption by the introduction of conditional includes, which are evaluated in the context of a repository. Right now, only one conditional exists with "gitdir:" -- it will only include the configuration if the current repository's git directory matches the value passed to "gitdir:". To support these conditionals, we have to break our API and make the repository available when opening a configuration file. This commit extends the `open` call of configuration backends to include another repository and adjusts existing code to have it available. This includes the user-visible functions `git_config_add_file_ondisk` and `git_config_add_backend`.

Several functions to retrieve variables from a repository only return immutable values, which allows us to actually constify the passed-in repository parameter. Do so to help a later patch, which will only have access to a constant repository.
