To further match how Git behaves, this change makes most of the
directories libgit2 creates in a git repo have a file mode of
0777. Specifically:
- Intermediate directories created with git_futils_mkpath2file() have
0777 permissions. This affects odb_loose, reflog, and refs.
- The top level folder for bare repos is created with 0777
permissions.
- The top level folder for non-bare repos is created with 0755
permissions.
- /objects/info/, /objects/pack/, /refs/heads/, and /refs/tags/ are
created with 0777 permissions.
Additionally, the following changes have been made:
- fileops functions that create intermediate directories have grown a
new dirmode parameter. The only exception to this is filebuf's
lock_file(), which unconditionally creates intermediate directories
with 0777 permissions when GIT_FILEBUF_FORCE is set.
- The test runner now sets the umask to 0 before running any
tests. This ensurses all file mode checks are consistent across
systems.
- t09-tree.c now does a directory permissions check. I've avoided
adding this check to other tests that might reuse existing
directories from the prefabricated test repos. Because they're
checked into the repo, they have 0755 permissions.
- Other assorted directories created by tests have 0777 permissions.
git_repository_config wants to take the global and system paths again
so that one can be explicit if needed.
The git_repository_config_autoload function is provided for the cases
when it's good enough for the library to guess where those files are
located.

GIT_EOVERFLOW means something different. Use GIT_ESHORTBUFFER. On the
way, remove a redundant sizeof(char).

1. The license header is technically not valid if it doesn't have a
copyright signature.
2. The COPYING file has been updated with the different licenses used in
the project.
3. The full GPLv2 header in each file annoys me.
Configurations when taken from a repository and remotes should be
identifiable as coming from a particular repository. This allows us to
reduce the amount of variables that the user has to keep track of.

The `stat` methods were having issues when called with a trailing slash
in Windows platforms.
We now use GetFileAttributes() where possible, which doesn't have this
restriction.
The old `git_fileops_prettify_path` has been replaced with
`git_path_prettify`. This is a much simpler method that uses the OS's
`realpath` call to obtain the full path for directories and resolve
symlinks.
The `realpath` syscall is the original POSIX call in Unix system and
an emulated version under Windows using the Windows API.
Cleaned up the structure of the whole OS-abstraction layer.
fileops.c now contains a set of utility methods for file management used
by the library. These are abstractions on top of the original POSIX
calls.
There's a new file called `posix.c` that contains
emulations/reimplementations of all the POSIX calls the library uses.
These are prefixed with `p_`. There's a specific posix file for each
platform (win32 and unix).
All the path-related methods have been moved from `utils.c` to `path.c`
and have their own prefix.
A bunch of redundant methods have been removed from the external API.
- All the reference/tag creation methods with `_f` are gone. The force
flag is now passed as an argument to the normal create methods.
- All the different commit creation methods are gone; commit creation
now always requires a `git_commit` pointer for parents and a `git_tree`
pointer for tree, to ensure that corrupted commits cannot be generated.
- All the different tag creation methods are gone; tag creation now
always requires a `git_object` pointer to ensure that tags are not
created to inexisting objects.
This function puts the global and repository configurations in one
git_config object and gives it to the user.

Now the ceiling_dirs are compared with their symbolic free version (like base_path).
The ceiling dirs check is now performed after getting the parent directory.
retrieve_device returns the file device for a given path (so that we can detect device change while walking through parent directories).
abspath returns a canonicalized path, symbolic link free.
retrieive_ceiling_directories_offset returns the biggest path offset that path match in the ceiling directory list (so that we can stop at ceiling directories).
