  Add support for atomic file locking The struct 'git_filelock' represents an atomically-locked file, git-style. Locked files can be modified atomically through the new file lock interface: int git_filelock_init(git_filelock *lock, const char *path); int git_filelock_lock(git_filelock *lock, int append); void git_filelock_unlock(git_filelock *lock); int git_filelock_commit(git_filelock *lock); int git_filelock_write(git_filelock *lock, const char *buffer, size_t length); Signed-off-by: Vicent Marti <tanoku@gmail.com>
