Main motivation here is in the next patch: getting access to ConfigParser
for pulling extra options out of x86/unittests.cfg.
Drop the README bits about manually invoking qemu-kvm/qemu-system: the
runner spits out the generated CLI if you want to invoke it by hand,
and since some tests want specific options the docs weren't correct
to begin with.
This also fixes the script to have a consistent exit status regardless
of the version of qemu we invoke.

-An example of a test invocation:
-Using qemu-kvm:
-qemu-kvm -device testdev,chardev=testlog -chardev file,id=testlog,path=msr.out -serial stdio -kernel ./x86/msr.flat
-This invocation runs the msr test case. The test outputs to stdio.
+To launch a test, use the runner script:
-Using qemu (supported since qemu 1.3):
-qemu-system-x86_64 -enable-kvm -device pc-testdev -serial stdio -device isa-debug-exit,iobase=0xf4,iosize=0x4 -kernel ./x86/msr.flat
+ ./x86-run ./x86/msr.flat
-Or use a runner script to detect the correct invocation:
-./x86-run ./x86/msr.flat
-To select a specific qemu binary, specify the QEMU=<path> environment:
-QEMU=/tmp/qemu/x86_64-softmmu/qemu-system-x86_64 ./x86-run ./x86/msr.flat
+To select a specific qemu binary: specify the QEMU=<path> environment:
+
+ ./x86-run --qemu /path/to/x86_64-softmmu/qemu-system-x86_64 ./x86/msr.flat
+
+./x86-run returns 1 if any passed test fails, 0 otherwise.
-The exit status of the binary (and the script) is inconsistent: with
-qemu-system, after the unittest is done, the exit status of qemu is 1,
-different from the 'old style' qemu-kvm, whose exit status in successful
-completion is 0.
