Resolves #510.

Disable timer interrupt to fix some bugs

Signed-off-by: liangzhen <zhen.liang@spacemit.com>

debug: Add Openocd.set_available()

debug: Better interlock when interacting with gdb CLI.

This helper uses dmi_write commands to mark harts
available/unavailable.

debug: Make Openocd.targets() tolerate blank lines.

debug: Fix interrupt_all() to restore state.

debug: Add --hart command line option to gdbserver.py

Actually wait for the command to be echoed back. This means we won't be
confused if there are extra newlines in gdb output.

This lets you reproduce a test running on a specific hart.

debug: Re-enable unavailable tests, and fix them for github

During the github workflow this character is \n, while on my computer
it's ' '. I'm sure there's a good reason for that, but it doesn't seem
worth figuring out what that reason is.

debug: Actually run tests in github workflow.

This should avoid problems like we just had where bad tests can break
the OpenOCD workflow. These tests only run if any debug files are
changed, so should have no impact at all on non-debug tests in this
repo.

This file is copied and then slightly changed from riscv-openocd. New
changes are that cacheable steps (building spike, OpenOCD) are stored to
the cache even if running the tests fails.

debug: Only run pylint if debug files changed.

Just doing this to make a change in the debug files, which should now
cause the pylint workflow to execute.

debug: Disable unavailable tests.

They have issues when run in a github workflow.

debug: Test OpenOCD behavior when harts become unavailable, using new spike mechanism

Use new spike mechanism to test OpenOCD behavior when a hart becomes
unavailable, and then available again.

Use new spike mechanism to test OpenOCD behavior when the current hart
becomes unavailable while running.

Create ThreadTerminated exception.

Use the new spike mechanism to test OpenOCD behavior when a hart becomes
unavailable while running.

Create CommandException.

It's a bit messy to read the log file to get the output, but it seems to
be flushed often so that this works.

Also, added the `targets` method for retrieving the list of targets,
and `wait_until_running` method to wait until all targets are in a
running state.

Just so it's easier to quickly comment out code and hard-code the target
to use without pylint complaining. This really should be a command line
option.

debug: flushregs -> maintenance flush register-cache

flushregs is deprecated.
