Revert 166085 - Selective build clobbering feature (landmines.py and android build scripts).

Revert 166085 - Selective build clobbering feature (landmines.py and android build scripts).

It looks like this made win extract_build fail.

Adds the ability for devs/troopers/etc. to set 'landmines' in the tree so that
the build will selectively clobber when a builder moves over a revision with such
a change.

This cl has an basis landmines.py, and hooks the clobber mechanism to the android
build scripts. 

The relevant cl which implements this for
compile.py is here: https://chromiumcodereview.appspot.com/11234013/

I'm planning to also implement an informational invocation for gclient to let devs know
about any potential landmines so they can decide if they need to clobber.

Yeah you're right, that's a problem, we should revert.
