libgit2 v0.26.3

on GitHub

This is a bugfix release. It includes the following non-exclusive list of
improvements, which have been backported from the master branch:

• Fix cloning of the libgit2 project with git clone --recursive by removing an
  invalid submodule from our testing data.

• Fix endianness of the port in p_getaddrinfo().

• Fix handling of negative gitignore rules with wildcards.

• Fix handling of case-insensitive negative gitignore rules.

• Fix resolving references to a tag if the reference is stored with its fully
  resolved OID in the packed-refs file.

• Fix checkout not treating worktree files as modified when only their mode has
  changed.

• Fix rename detection with GIT_DIFF_FIND_RENAMES_FROM_REWRITES.

• Enable Windows 7 and earlier to use TLS 1.2.
