Cleanup in base. This moves the implementation (and a bunch of header file
dependencies) from the multiprocess test and the test_suite headers to .cc
files. Moves multiprocess_test to the test directory, and all of this stuff to
the existing base_test_support project. I also used the base namespace.

Previously other projects included this functionality just by #include because
it was all inline, so I had to add dependencies on base_test_support in a few
places.

Moves and renames the command line switch this was using to base_switches. Move
the base switch for process type to chrome switches.

multiprocss_test.{cc|h} and test_suite.{cc|h} shouldn’t be needed in this target
(base_unittests) now that it depends on test_support_base.

I guess the \n is there to keep things from going past 80 columns? The second
sentence does go beyond 80, though.
