These are no longer split out and shared in the root build/ directory.
This does result in a small amount of overhead from building redundant
copies of these files, although the overhead is not significant. When
building 7 different variants of gem5, all the ISAs and NULL, the
difference on my machine was:
Before:
real 41m25.372s
user 914m22.266s
sys 41m51.816s
After:
real 42m38.074s
user 921m36.852s
sys 43m2.949s
This is about a 2-3% difference, which is a worse than typical case,
since the overhead scales with the number of variants being built.
The benefit of pulling ext/ into the variant directory is that there can
now be a single config which applies to all files used to build gem5,
and that config is represented by the variant of gem5 being built.

scons seems to get confused in some situations when this is a single
large string and passes it as one big argument to g++ instead of
breaking it up into several arguments.
We need to do the work for it and break it into individual arguments,
like what was already being done with GTEST_LIBS.
Also wrap some overly long lines.

googlemock needs to be built together with googletest. This patch
is enabling it by doing the following things
* Moving googletest and googlemock under the same top level directory,
so that we have a single SConscript for building them.
This also matches googletest directory structure:
googletest
|_googletest
|_googlemock
* Adding a shared SConscript which is building gmock and gtest as libgtest
* Removing googletest/SConscript

A static library is built using gtest-all.cc and includes the gtest
main function from gtest_main.cc. extra libraries to use when linking
are included in the main environment variable GTEST_LIBS, and extra
CPPFLAGS are in GTEST_CPPFLAGS. The library's path is added to the
library search path, and it's headers to the header search path.
