  fileops/repository: create (most) directories with 0777 permissions
  
  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.
