Thanks to Emeric.

It's redundant to do this (git doesn't) and Windows doesn't allow us
to overwrite a read-only file (which objects are).

Do not add the `git2` path to internal includes, or that will cause
an extra path dependency.

Comes with schu's stress tests for config files. Hopefully the diffs
will stay minimal from now on.

That makes more sense to me.

refs: permissions-related fixes/improvements

This groups the #define with the other ref-related file modes, and it
makes the name consistent with the other packed-refs definitions.

This matches stock Git's behavior.

Fix docs about the command to mix the clay tests

See `global.c` for a description of what we're doing.

When libgit2 is built with GIT_THREADS support, the threading system
must be explicitly initialized with `git_threads_init()`.

test_helpers: do not rely on assert

References! References! References!

This function should exit after printing usage information if too few
arguments were specified.

Additionally, it should exit with a failure status if the first argument
supplied is not one in the internal command list.

Since git__free is not exported (it's actually a macro), it should not be
used in client programs.  Change this call to 'git__free' back to 'free'.

This new version of the references code is significantly faster and
hopefully easier to read.

External API stays the same. A new method `git_reference_reload()` has
been added to force updating a memory reference from disk. In-memory
references are no longer updated automagically -- this was killing us.

If a reference is deleted externally and the user doesn't reload the
memory object, nothing critical happens: any functions using that
reference should fail gracefully (e.g. deletion, renaming, and so on).

All generated references from the API are read only and must be free'd
by the user. There is no reference counting and no traces of generated
references are kept in the library.

There is no longer an internal representation for references. There is
only one reference struct `git_reference`, and symbolic/oid targets are
stored inside an union.

Packfile references are stored using an optimized struct with flex array
for reference names. This should significantly reduce the memory cost of
loading the packfile from disk.

git_reference_rename() didn't properly cleanup old references given by
the user to not break some ugly old tests. Since references don't point
to libgit's internal cache anymore we can cleanup git_reference_rename()
to be somewhat less messy.

Since references are not owned by the repository anymore we have to free
them manually now.

Currently libgit2 shares pointers to its internal reference cache with
the user. This leads to several problems like invalidation of reference
pointers when reordering the cache or manipulation of the cache from
user side.

Give each user its own git_reference instead of leaking the internal
representation (struct reference).

Add the following new API functions:

	* git_reference_free
	* git_reference_is_packed

git_config_get_int --> git_config_get_int32

The functions loose_object_mode and loose_object_dir_mode call stat
inside an assert statement which isn't evaluated when compiling in
Release mode (NDEBUG) and leads to failing tests. Replace it.

Status: fix segfault (#465) and order issues

This ensures that entries from the working directory are retrieved according to the following rules:

 - The file "subdir" should appear before the file "subdir.txt"
 - The folder "subdir" should appear after the file "subdir.txt"

status: Add a file in the test repository to cover the correct sorting of entries when the working folder is being read

In this case, "subdir.txt" should be listed before the "subdir" directory.

Fixes #465

Create objects, indexes, and directories with the right file permissions

Ensure that all memory related functions (malloc, calloc, strdup, free,
etc) are using their respective `git__` wrappers.
