When a test is complete, the output files are in a random folder
in /tmp.
This commit adds a procedure copying those files to
testing-results/SuiteUID/TestUID/ folder, where SuiteUID and
TestUID are the corresponding uid's of the test.
This procedure is triggered after a test is complete and before
the folder in /tmp being removed.

Made DRAMCtrl a ClockedObject, with DRAMInterface
defined as an AbstractMemory. The address
ranges are now defined per interface. Currently
the model only includes a DRAMInterface but this
can be expanded for other media types.
The controller object includes a parameter to the
interface, which is setup when gem5 is configured.

Previously `tests/gem5/fs/linux/arm/run.py` contained an ugly,
hard-coded `gem5_root` variable. In this commit we pass `gem5_root`
as an argument from `tests/gem5/fs/linux/arm/test.py`, utilizing
`config.base_dir`.

We were downloading resources to various different locations, for no
real reason. This standardizes the process. From this commit onwards,
all testing resources are downloaded to `tests/gem5/resources` by
default. This may be overriden via the `--bin-path` TestLib argument.
Note: In order to do this I have changed the meaning of the `bin-path`
TestLib argument slightly. Previously the `bin-path` assumed a flat
(non-existant) hierarchy. A simple directory of local resources. This
new bin-path functionality maintains logical sub-directories. This is
technically an API change and will be noted in the release notes.

This is part of a process of getting rid of the `tests/config`
directory, and placing these configs either where they are used,
removing them if unneeded, or moving them to `configs/example`.
These config files, in this patchset, are part of the realview tests
found in `tests/gem5/fs/linux/arm/`. They have been moved to
`tests/gem5/configs`.

As mentioned on the JIRA issue, uncacheable requests done after
cacheable requests had been done to the address make the cache writeback
and write trash data to memory.
We believe that the kernel must be doing earlier invalidation by set and
way earlier on to prevent this, but that is not implemented in gem5 yet.
The problem can be worked around by booting in atomic without caches and
checkpointing after init, because uncacheable accesses are only done on
early stages of CPU bringup, which is the more common use case anyways.
The aarch64 Linux kernel developers have stated that set and way
invalidates are not going to be used in aarch64, which further reduces the
importance of implementing this immediatly

The "hello" tests that were previously ignored are all functioning
correctly, and are therefore being re-included in the test suite. The
MIPS and SPARC tests have been tagged a "long" as we do not compile
these ISAs are part of our "quick" tests.

In verifier.py, testlib.test_util is imported and renamed to 'test',
while several functions in the file have a subfunction named 'test()',
which causes test.fail() to fail as 'test' points to the
subfunction instead of the module.
This commit addresses the above issue by keeping the imported module
as test_util instead of renaming it to test.

This catches ruby functional memory errors we have observed, and ensures
that ruby_mem_test.py itself won't be broken.
The test duration is about 10 seconds, and it can be run as:
./main.py run --uid SuiteUID:tests/gem5/test_ruby_mem_test.py:test-ruby\
_mem_test-NULL-x86_64-opt

- ruby_random_test.py
- ruby_direct_test.py
These tests are factored out with the tests for:
- memcheck.py
- ruby_mem_test.py
Each new test was calibrated to last about 5 seconds on a Lenovo ThinkPad

The file was raising due to the undefined constant `verifiers`, leading
the test to be ignored.
./main.py list -v
would show this as:
```
Traceback (most recent call last):
File "/gem5/tests/../ext/testlib/loader.py", line 239, in load_file
execfile(path, newdict, newdict)
File "/gem5/tests/gem5/memcheck/test_memcheck.py", line 32, in <module>
verifiers=verifiers,
NameError: name 'verifiers' is not defined
Exception thrown while loading "/gem5/tests/gem5/memcheck/test_memcheck.py"
Ignoring all tests in this file.
```
The test has been modified to have an empty verifiers list, which should
still catch bugs since src/mem/mem_checker.cc has several asserts already
which would be caught by the test system due to the exit status.
Also make the following changes to the test:
- move it to tests/gem5/memory/test.py with other memory tests.
This makes it easier to see all the tests in the source in one go, and
might make it easier to factor certain memory things out later on.
- reduce --maxtick to a value that finishes in 7 seconds on a Lenovo
ThinkPad P51.
The previous value would take 50x longer, which feels too long for a
single test.
- enable --prefetchers to also stress a prefetcher in the test

Before this change, running:
./build/NULL/gem5.opt configs/example/ruby_mem_test.py -m 20000000 \
--functional 10
would only print warning for memory errors such as:
warn: Read access failed at 0x107a00
and there was no way to make the simulation fail.
This commit makes those warnings into errors such as:
panic: Read access failed at 0x107a00
unless --suppress-func-errors is given.
This will be used to automate MemTest testing in later commits.

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.
