Merge branch 'jk/submodule-name-verify-fix' into jk/submodule-name-verify-fsck

* jk/submodule-name-verify-fix: verify_path: disallow symlinks in .gitmodules update-index: stat updated files earlier verify_path: drop clever fallthrough skip_prefix: add icase-insensitive variant is_{hfs,ntfs}_dotgitmodules: add tests path: match NTFS short names for more .git files is_hfs_dotgit: match other .git files is_ntfs_dotgit: use a size_t for traversing string submodule-config: verify submodule names as paths Note that this includes two bits of evil-merge: - there's a new call to verify_path() that doesn't actually have a mode available. It should be OK to pass "0" here, since we're just manipulating the untracked cache, not an actual index entry. - the lstat() in builtin/update-index.c:update_one() needs to be updated to handle the fsmonitor case (without this it still behaves correctly, but does an unnecessary lstat).
