Huge thanks to piman@ for working on a patch. I chose a different design but he
gave me motivation and ideas. Sorry for not accepting his patch earlier, this
was mostly due to broken gclient implementation itself.
gclient can now run an unlimited number of parallel checkouts and always keep
the checkout coherency correct.
--jobs=1 is single threaded as before, albeit with a different code path.
Issues:
- Using --jobs with a value other than 1 will result in a mangled output.
- Exceptions thrown in a thread will be have the wrong stack trace.
TEST=gclient sync -j 99 in a ssh:// chromiumos checkout is dramatically faster.

Here's the perf on linux on i7-860 for a chromium checkout with warm cache. Cold
cache will result is significantly reduced improvements so this is best case
improvements. The sync was no-op all the time except where noted. All execution
where with "time gclient sync " + args. Didn't include 'sys' column since it was
statistically insignifiant and highly correlated with 'user'.

It's still faster than a no-op sync without parallel checkout.

#3 This is depot_tools@56020
#4 Since -f implies runhooks, I ran the hook 'python src/build/gyp_chromium'
manually to compare. Hooks are still run in a single thread. I didn't rest
'gclient runhooks'.
I tried to go a ssh:// checkout of chromium os tree but it timed out everytime I
tried to sync so I couldn't get data points. I expect an order of magnitude of
improvement or more.

Instead of keeping the reference information in the parent, note for each Dependency if it should be processed with self.should_process. I had to hack a bit with the hooks to also enforce recursion_limit() to keep the old behavior, otherwise From() could cause hooks to run that weren't run before.

ExecutionQueue takes care of reordering execution depending on each Dependency
requirements. There is no need to sort anymore.
ExecutionQueue also manages the Progress instance and is multithread safe, in preparation to parallel checkout.

Add Dependency.processed and .hooks_ran to ease debugging.

Bring some OOP and sanity to gclient.py.
- Changed the algorithm from breadth-first to depth-first.
- Added infinite recursion support.
- Fixed From() of From() dependency.
- Fixed cross solution custom deps aliasing.
- Removed support code for old .gclient_entries format.
- Removed IsGitCheckout() in favor for a direct check for .git presence.
TEST=all test pass
The main difference with r51760 is that new smoke tests have been added since which replicates how webkit checkouts with gclient.
