[PATCH 1/2] refs: remove unused function invalidate_ref_cache

[Stefan Beller]

The function 'invalidate_ref_cache' was introduced in 79c7ca5 (2011-10-17,
invalidate_ref_cache(): rename function from invalidate_cached_refs())
by a rename and elevated to be publicly usable in 8be8bde (2011-10-17,
invalidate_ref_cache(): expose this function in the refs API)

However it is not used anymore, as 8bf90dc (2011-10-17, write_ref_sha1():
only invalidate the loose ref cache) and (much) later 506a760 (2013-04-22,
refs: change how packed refs are deleted) removed any calls to this
function. So it seems as if we don't need that function any more,
good bye!

[PATCH 2/2] cache: remove unused function 'have_git_dir'

[Stefan Beller]

This function was added in d2b0708 (2008-09-27, add have_git_dir()
function) as a preparation for adbc0b6 (2008-09-30, cygwin: Use native
Win32 API for stat).

However the second referenced commit was reverted in f66450a (2013-06-22,
cygwin: Remove the Win32 l/stat() implementation), so we don't need to
expose this wrapper function any more as a public API.

Looks good.  Stefan, thanks for cleaning up after me!
