Depending on configuration, the existing implementation of watchpoints is
rather inefficient for certain scenarios. Consider HW that:
1. triggers 0-3 can be used as instruction breakpoints
2. triggers 4-7 can be used as data breakpoints (watchpoints)
3. NAPOT triggers are not supported.
Now, consider that we have a pending watchpoint. And we perform a "step"
operation. According to the current implementation:
* OpenOCD will disable watchpoints
* Perform a single-step
* Will try to restore the original watchpoints. It will need 12 attempts
to find a suitable trigger: (8 attempts to try NAPOT, and another 4 to try
GE+LE).
This patch introduces a dedicated cache for requests to triggers. It
significantly speeds things up, since we cache failed attempts and no
additional interactions with HW is necessary.

Otherwise it won't compile for me. Not sure why that doesn't affect the
automated builds.

Targets "esp32c2" and "esp32c3" should not be mentioned in the doc
under "target types" because these are not standalone OpenOCD
targets.
They are merely a set of .cfg files which use the generic
"riscv" target.

Now:
1) If mmu is disabled, virt2phys succeeded and returns physical address
2) If mmu is enbaled, but translation fails, read/write_memory fails

This incorrect extra call has been removed in upstream code already
in March 2022, see https://review.openocd.org/c/openocd/+/6836 .
Remove it from riscv-openocd as well.

Upstream has a checkpatch failure here. I had fixed it because I didn't
know how else to properly get around it back then. Reintroduce the
problem. Now this file is identical to upstream.

When a target in an SMP group is unavailable, the gdb layer might get an
event for a different target in that SMP group, but not one that is the
primary target for that gdb connection. So propagate events if they're
for any of the targets in the SMP group, not just if it's for the first
one in that group.

Exit early if conditions aren't satisfied, instead of putting the core
code inside an if().
Also return ERROR_FAIL if conditions are satisfied but no matching
registers were found.
