The sandbox module is providing a sandbox environment for
a specific TestCase via the multiprocessing package.
This isolation/complexity is not strictly needed as testlib is already
forking a new process via subprocess. As it is now, a TestRunner will
generate:
TestRunner -> multiprocessing.Process -> subprocess.Popen
(2 generated procs)
With this patch we are removing the intermediate layer
TestRunner -> subprocess.Popen
(1 generated proc)

As we are now going to maintain different bundles of resources for each
gem5 release, the resources have been archived to
http://dist.gem5.org/dist/current for gem5 19. The development branch
will use http://dist.gem5.org/dist/develop going forward. New releases
will follow the format http://dist.gem5.org/dist/{VERSION}.
This patch makes the resources url a command-line parameter, set to the
"correct" url by default. This will be updated to the correct, archived,
version subdirectory upon release of a new gem5 version. E.g.:
http://dist.gem5.org/dist/v20 for the gem5 20 release.
Some Make files have been cleaned up to no longer fetch and push to
remote locations. As gem5-resources is implemented, sources will be
moved to the gem5-resources resository and compiled binaries, etc.
pulled from our Google Cloud bucket from the tests themselves.

A host tag has been added to take into consideration the host ISA which
is running gem5 (default is X86).
There might be regressions which are supposed to be run on a particular
host machine only. This could be the case of dynamically linked
regressions which require dynamic linker/loader + shared libraries of
the same ISA as the target.

So far lots of tests will download binaries inside the gem5 directory.
The path is also specific to the test being run.
This doesn't play well with an environment where gem5 is cloned from
scratch for every build, or if several gem5 are cloned in a single
machine.
Binaries will be automatically downloaded every time this happens.
This patch is adding a --bin-path option, so that it's possible to
setup a fixed directory with all pre-downloaded binaries.
By default it is set to None to preserve original behaviour.

Gem5Fixture is used to define a fixture for building the gem5
binary. Most tests are expected to define their own Gem5Fixture,
however, as some might depend on the same binary (e.g.,
./build/ARM/gem5.opt), they will try to re-define a fixture for the
same target. This patchset changes Gem5Fixture to derive from
UniqueFixture.
In addition, this patchset changes the way global fixtures are
discovered to work with the new Gem5Fixture class. Instead of
enumerating them when test definitions are loaded, we do so after the
tests have been filtered according to specified tags (e.g., include
opt variant, exclude fast, debug variants).

When creating the separator for printing things to the terminal (=.*) we
use an ioctl that isn't supported in some sandboxed environments. When
running on the Google jenkins server (kokoro) it errors with an IOError.

Custom exceptions are not always properly pickled which could lead to
the sandbox test executor to crash when it tries to re __init__ pickled
exceptions thrown from the failed test.
