git_cache: lower max num of .pack files before re-bootstrap on Win. 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`.

Tools for working with Chromium development. It requires python 2.7.
The most important tools are:
fetch: A gclient wrapper to checkout a project. Use fetch --help for more details.gclient: A meta-checkout tool. Think repo or git submodules, except that it support OS-specific rules, e.g. do not checkout Windows only dependencies when checking out for Android. Use gclient help for more details and README.gclient.md.git cl: A code review tool to interact with Rietveld or Gerrit. Use git cl help for more details and README.git-cl.md.roll-dep: A gclient dependency management tool to submit a dep roll, updating a dependency to a newer revision.There are a lot of git utilities included.
depot_tools updates itself automatically when running gclient tool. To disable auto update, set the environment variable DEPOT_TOOLS_UPDATE=0.
To update package manually, run update_depot_tools.bat on Windows, or ./update_depot_tools on Linux or Mac.
On Windows only, running gclient will install git and python.
