Evgeniy Naydanov 00320fd198 target/riscv: replace `__PRETTY_FUNCTION__` with `__func__`
The reasoning for the change:
* `__func__` is part of C99, `__PRETTY_FUNCTION__` is GNU extension.
* `__PRETTY_FUNCTION__` is defined to be the same as `__func__` for C
  sources by GCC documentation but differ for C++ sources (full
  signature instead of just a name).
* Currently Clang does support `__PRETTY_FUNCTION__`, though it uses
  GCC's C++ variant across C and C++.

Therefore using `__PRETTY_FUNCTION__` creates confusion and does not
provide any valueble information in the logs.

Evgeniy Naydanov 3b0c654c67 target/riscv: dump_field() shouldn't always decode
Sometimes, the value from of some DMI scans has no meaning (e.g. when
`op` is read). Such values should not be decoded. To make the dumps more
consistent, `<no decoding available>` is printed when there is no
decoding for a register.

Evgeniy Naydanov 5ec9938c61 target/riscv: clarify usage of `coreid`
By definition in `target/target.h`, `coreid` is not a unique identifier
of a target -- it can be the same for targets on different TAPs.

Marek Vrbka 2357237815 target/riscv: Replace watchpoint value mask comparison value with macro.
This patch replaces ~(typeof(watchpoint->mask))0 with
WATCHPOINT_IGNORE_DATA_VALUE_MASK. This improves
readability and moves the RISCV target in line with
other targets.

Anastasiya Chernikova fea20e2bf5 target/riscv: cache requests to trigger configuration
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.

Marek Vrbka adb9c3209e target/riscv: Stop caching writes to DPC
Since DPC is WARL (same rules as MEPC according to
the specification), it is possible that
writes to it won't result in the exact value present.
Therefore, writes to it shouldn't be cached, same as
with other WARL registers.

Tim Newsome 52c9ae0aa1 server/gdb_server: Handle events if first target is unavailable
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.
