We don't set the branch.<name>.gerritpatchset git config value
during "git cl upload" because it isn't returned from the
server either during push or during any of our subsequent RPCs,
and adding another RPC just for that metadata would be slower
that we would like.

But calling "git cl status" already makes an RPC per branch, so
take advantage of that to cache the gerritpatchset value during
that operation.

$ git checkout <name>

may be interpreted by git as checking out a file named <name>
if <name> has slashes. Thus,

$ git checkout infra/config

ends up checking out infra/config directory of the (typically)
master branch that was checked out before. To avoid confusion,
we have to add '--' separator between branch name and file names:

$ git checkout <name> --

This in turns allows to run CQ-based presubmit on infra/config branches.

  skipping mirror update, it has rev=ea5df8e78fbd0a4c24cc3a1f3faefefcd1b45237 already

thereby saving on needless git fetch (~40s in glcient sync on win trybots),
and reducing the rate of .pack file accumulation inside cache directories.


Risks: silently broken recipes which run gclient sync (or worse, bot_update)
as a means of fetching latest commits in all repos of a solution. I think
the benefit of faster bot_update in chromium CQ is worth the potential risk.

It used to be 50, I think ~9 gives best results for Chromium on Win:
  on golo VM, it takes <4 minutes to re-boostrap + git fetch small
  delta, assuming zipped git checkout for bootstrap is fresh (~1day).

For other repos, which are significantly smaller, this change should
have minor effect if at all.

Test: I tested this using `led` tool on Win7 machines running LUCI
stack extensively. For example,

  * https://ci.chromium.org/swarming/task/3a0102e8c8657410
    shows case with few .pack files, hence just 1 fetch

  * https://ci.chromium.org/swarming/task/3a010282f9fd8010
    shows case with 39 .pack files and so bootstrapping + fetch.
    If you look at prior tasks on the same VM, you'd find this:
    https://ci.chromium.org/swarming/task/39ffe843d01ed010
    which spent 8 minutes doing 1 incremental fetch with 39 .pack
    files.

**Troopers/Sheriffs**: This change is safe to revert.
However, beware that you should also at the same time revert the recipe
roll of this CL to the repo, in which the failed builder's recipe is
located, typically `chromium/tools/build`.
