refs: Speed up packed lookups.
Currently ref lookups require loading the entire packed-refs file into
a hashmap in memory. For repos with large numbers of refs this can be
painfully slow.
This patch replaces the existing lookup code and instead mmap()'s the
packed-refs file and performs a binary search to locate the ref entry.
Git uses a similiar approach.
The old hash table codepath is still used for unsorted packed-refs files.
This patch also fixes a minor bug where the "peeled" trait is never
parsed correctly from the packed-refs header.

tests: refs::crashes: create sandbox for creating symref
The test `refs::crashes::double_free` operates on our in-source
"testrepo.git" repository without creating a copy first. As the test
will try to create a new symbolic reference, this will fail when we want
to do a pure out-of-tree build with a read-only source tree.
Fix the issue by creating a sandbox first.

Remove the signature from ref-modifying functions
The signature for the reflog is not something which changes
dynamically. Almost all uses will be NULL, since we want for the
repository's default identity to be used, making it noise.
In order to allow for changing the identity, we instead provide
git_repository_set_ident() and git_repository_ident() which allow a user
to override the choice of signature.

refs: remove the _with_log differentiation
Any well-behaved program should write a descriptive message to the
reflog whenever it updates a reference. Let's make this more prominent
by removing the version without the reflog parameters.
