3ac80f9f55 util: Make running m5 util unit tests opt-in.
These tests don't run reliably right now for a few reasons, including
problems with QEMU, and apparently inaccurate information from g++-s
--print-sysroot option.

This may be revisited in the future if those problems can be sorted out.
For now, avoid tripping up new people who won't know to (or how to) work
around those sorts of errors.

aaf7678670 util: Automatically load the java .so in the gem5 ops wrapper.
The java wrapper which provides access to the gem5 ops is implemented
using JNI in a .so file which needs to be loaded before the class can be
used. Rather than expecting the caller to do that, we can use a static
block in the class definition. We know that will be called at the right
time, and it's one less detail (arguably an implementation detail) that
the caller won't have to worry about.

666b7904e6 util: Reorganize the java wrapper for gem5 ops.
Rather than use a top level package of jni which is generic, switch to a
top level package of "gem5". With that prefix, call the actual class
Ops, which is capitalized according to Java tradition and also
unambiguous given its package name.

Also move the java class definition and c JNI implementation into a java
subdir to keep it all together. The java related output will now be in
out/java for the same reason.

6e0f211046 util: Add a --verbose flag to the m5 util's scons.
Like gem5's own verbose scons flag, when this isn't provided, the output
is very brief and just shows what is being built and by what type of
process. When it is provided, the full command lines are printed.

This is less fancy than the version gem5 has, but I didn't want to
duplicate all that code. We should find a way to share that and other
functionality between different sets of scons scripts.

385bbc863e util: Add a --no-test-xml option to the m5 util's scons.
This forces the test XML output files to be omitted from the build. This
lets you run scons build/ to build everything without running any tests,
and can be used to verify that everything builds correctly even if the
tests don't run/pass.

This is a fairly comprehensive document which describes how to use the
m5 utility, the various libraries/modules, and the various included
tests.
