* sp/mmap: (27 commits)
Spell default packedgitlimit slightly differently
Increase packedGit{Limit,WindowSize} on 64 bit systems.
Update packedGit config option documentation.
mmap: set FD_CLOEXEC for file descriptors we keep open for mmap()
pack-objects: fix use of use_pack().
Fix random segfaults in pack-objects.
Cleanup read_cache_from error handling.
Replace mmap with xmmap, better handling MAP_FAILED.
Release pack windows before reporting out of memory.
Default core.packdGitWindowSize to 1 MiB if NO_MMAP.
Test suite for sliding window mmap implementation.
Create pack_report() as a debugging aid.
Support unmapping windows on 'temporary' packfiles.
Improve error message when packfile mmap fails.
Ensure core.packedGitWindowSize cannot be less than 2 pages.
Load core configuration in git-verify-pack.
Fully activate the sliding window pack access.
Unmap individual windows rather than entire files.
Document why header parsing won't exceed a window.
Loop over pack_windows when inflating/accessing data.
