d5d5d7b641 gc: automatically write commit-graph files
The commit-graph file is a very helpful feature for speeding up git
operations. In order to make it more useful, make it possible to
write the commit-graph file during standard garbage collection
operations.

Add a 'gc.commitGraph' config setting that triggers writing a
commit-graph file after any non-trivial 'git gc' command. Defaults to
false while the commit-graph feature matures. We specifically do not
want to have this on by default until the commit-graph feature is fully
integrated with history-modifying features like shallow clones.

59fb87701f commit-graph: add '--reachable' option
When writing commit-graph files, it can be convenient to ask for all
reachable commits (starting at the ref set) in the resulting file. This
is particularly helpful when writing to stdin is complicated, such as a
future integration with 'git gc'.

e0fd51e1d7 fsck: verify commit-graph
If core.commitGraph is true, verify the contents of the commit-graph
during 'git fsck' using the 'git commit-graph verify' subcommand. Run
this check on all alternates, as well.

We use a new process for two reasons:

1. The subcommand decouples the details of loading and verifying a
   commit-graph file from the other fsck details.

2. The commit-graph verification requires the commits to be loaded
   in a specific order to guarantee we parse from the commit-graph
   file for some objects and from the object database for others.

283e68c72f commit-graph: add 'verify' subcommand
If the commit-graph file becomes corrupt, we need a way to verify
that its contents match the object database. In the manner of
'git fsck' we will implement a 'git commit-graph verify' subcommand
to report all issues with the file.

Add the 'verify' subcommand to the 'commit-graph' builtin and its
documentation. The subcommand is currently a no-op except for
loading the commit-graph into memory, which may trigger run-time
errors that would be caught by normal use. Add a simple test that
ensures the command returns a zero error code.

If no commit-graph file exists, this is an acceptable state. Do
not report any errors.

  grep: keep all colors in an array
  Add and use generic name->id mapping code for color slot parsing

"git diff" compares the index and the working tree.  For paths
added with intent-to-add bit, the command shows the full contents
of them as added, but the paths themselves were not marked as new
files.  They are now shown as new by default.

"git apply" learned the "--intent-to-add" option so that an
otherwise working-tree-only application of a patch will add new
paths to the index marked with the "intent-to-add" bit.

* nd/diff-apply-ita:
  apply: add --intent-to-add

b2453d3449 RelNotes 2.18: clarify where directory rename detection applies
Mention that this feature works with some commands (merge and cherry-pick,
implying that it also works with commands that build on these like rebase
-m and rebase -i).  Explicitly mentioning two commands hopefully implies
that it may not always work with other commands (am, and rebase without
flags that imply either -m or -i).

Also, since the directory rename detection from this cycle was
specifically added in merge-recursive and not diffcore-rename, remove the
'in "diff" family" phrase from the note.  (Folks have requested in the
past that `git diff` detect directory renames and somehow simplify its
output, so it may be helpful to avoid implying that diff has any new
capability here.)

then clone from this. Having the local cloned copy also sync
from Perforce just isn't useful.

f55b87c1c7 git-p4: add options --commit and --disable-rebase
On a daily work with multiple local git branches, the usual way to
submit only a specified commit was to cherry-pick the commit on
master then run git-p4 submit.  It can be very annoying to switch
between local branches and master, only to submit one commit.  The
proposed new way is to select directly the commit you want to
submit.

Add option --commit to command 'git-p4 submit' in order to submit
only specified commit(s) in p4.

On a daily work developping software with big compilation time, one
may not want to rebase on his local git tree, in order to avoid long
recompilation.

Add option --disable-rebase to command 'git-p4 submit' in order to
disable rebase after submission.
