Add git_docs folder to depot_tools.
Includes trial documentation for git-freeze and git-thaw, as well as a
make_docs.sh script which generates man and html documentation from the input
asciidoc files, using git 1.9's documentation toolchain.

+=============
+
+NAME
+----
+git-freeze - Freeze all changes on a branch (indexed and unindexed)
+
+SYNOPSIS
+--------
+[verse]
+'git freeze'
+
+DESCRIPTION
+-----------
+
+`git freeze` works a lot like `git stash`, in that it stores the current changes
+in your working copy and index 'somewhere'. Unlike `git stash`, `git freeze`
+stores those changes on your current branch. This effectively allows you to
+'pause' development of a branch, work on something else, and then come back to
+exactly the same working state later (by running `git thaw`).
+
+`git freeze` will make up to 2 commits on your branch. A commit with the message
+`FREEZE.indexed` will contain all changes which you’ve added to your index (like
+with 'git add', 'git mv', 'git rm', etc.). A commit with the message
+`FREEZE.unindexed` will contain all changes which were not in your index at the
+time you ran git freeze (freshly modified files, new files, etc.).

+git-thaw(1)
+=============
+
+NAME
+----
+git-thaw - Un-freeze all changes on a frozen branch.
+
+SYNOPSIS
+--------
+[verse]
+'git thaw'
+
+DESCRIPTION
+-----------
+
+`git thaw` takes a frozen branch (as made by linkgit:git-freeze[1]), and returns
+it to the status that it was in before it was frozen.
+
+If you freeze a branch multiple times (i.e. change files, freeze, change files,
+freeze), `git thaw` will thaw all of the freezes.
