Add `rename_threshold` to `git_status_options`.

ntmlclient: fix linking with libressl

Remove PSGit from Language Bindings section of README

PSGit is not using libgit2 library. It is stub of a library and is not developed further.

ci: build with ssh on nightly

remote: refactor insteadof application

Using the insteadof helper would leak memory when we didn't really want
the pushInsteadOf configuration.  Refactor the choice into the function
that allocates memory (or now, not) and use a more idiomatic `int`
return code.

See commit f0e693b1

Since we are able to give our own git checkout options,
the default git checkout strategy will be the same as
initialized in a new git_checkout_options struct.

Extend the `git_worktree_add_options` to include `git_checkout_options`.

blob: identify binary content

Config parsing

git_commit_summary: ignore lines with spaces

remotes: fix insteadOf/pushInsteadOf handling

Better revparse compatibility for at time notation

Fix a long long that crept past

cmake: use project-specific root variable instead of CMAKE_SOURCE_DIR

Also applies to *_BINARY_DIR.

This effectively reverts 84083dcc,
which broke all users of libgit2 that use it as a CMake subdirectory
(via `add_subdirectory()`). This is because CMAKE_SOURCE_DIR refers
to the root-most CMake directory, which in the case of
`add_subdirectory()` is a parent project to libgit2 and thus the paths
don't make any sense to the configuration files. Corollary,
CMAKE_SOURCE_DIR only makes sense if the CMake project is always the
root project - which can rarely be guaranteed.

In all honesty, CMake should deprecate and eventually remove
CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR. It's been the source of headaches
and confusion for years, they're rarely useful over
CMAKE_CURRENT_(SOURCE|BINARY)_DIR or PROJECT_(SOURCE|BINARY)_DIR,
and they cause a lot of confusing configuration and source
code layouts to boot.

Any time they are used, they break `add_subdirectory()` almost 100% of
the time, cause confusing error messages, and hide subtle bugs.

Introduce `git_blob_data_is_binary` to examine a blob's data, instead of
the blob itself.  A replacement for `git_buf_is_binary`.

Introduce `git_object_rawcontent_is_valid`

Users may want to validate raw object content; provide them a function
to do so.

Return `GIT_EINVALID` on parse errors so that direct callers of parse
functions can determine when there was a failure to parse the object.

The object parser functions will swallow this error code to prevent it
from propagating down the chain to end-users.  (`git_merge` should not
return `GIT_EINVALID` when a commit it tries to look up is not valid,
this would be too vague to be useful.)

The only public function that this affects is
`git_signature_from_buffer`, which is now documented as returning
`GIT_EINVALID` when appropriate.

Minor code cleanups

Fixes libgit2/libgit2#6065

Fix repo init when template dir is non-existent

Instead of using the project-specific `libgit2_SOURCE_DIR` and
`libgit2_BINARY_DIR` variables, use `CMAKE_SOURCE_DIR` and
`CMAKE_BINARY_DIR`.

The filebuf functions should use hashes directly, not indirectly
using the oid functions.
