Antonio Borneo 54037d7b98 Move FD_SETSIZE to configure.ac
The commit from the pull request #644 sets the macro FD_SETSIZE to
128 for every host OS, while it is needed on Windows only.
Note that this macro has a much higher value on other OS and after
this commit it get reduced to 128 only.

Since in configure.ac is already present a hook to change the
compile defines for Windows, move there also FD_SETSIZE.

Evgeniy Naydanov 4c45762d76 target/breakpoints: fix types in `watchpoint_add_internal()`
There was a conflict:
1. commit 2cd8ebf44d ("breakpoints: use 64-bit type for watchpoint mask
   and value")
2. commit 0bf3373e80 ("target/breakpoints: Use 'unsigned int' for
   length")

The second commit was created erlier, but merged later so the types of
`mask` and `value` became `uint32_t` in `watchpoint_add_internal()`.

This created a bug:
`WATCHPOINT_IGNORE_DATA_VALUE_MASK` is defined as `(~(uint64_t)0)`.
Truncation to uint32_t makes it so the comparisons with the constant
don't work.

Jessica Clarke fd7b66c5eb binarybuffer: Fix inverted return value in buf_cmp
This is the fast path for when there is a mismatch in the leading whole
bytes, which means we should return true to indicate not equal like all
the other cases here and in the surrounding functions. Otherwise we'll
incorrectly report _buf1 == _buf2 if and only if there are mismatches in
the leading whole bytes.

This was introduced during the refactor and optimisation referenced
below.

The only in-tree caller of this is jtag_check_value_inner, which will
just fail to catch some errors. However, downstream in riscv-openocd it
gets used in the riscv target to determine whether an IR scan is needed
to select the debug module, and with an IRLEN >= 8 this breaks resetting
if the encoding for the DMI isn't all-ones in its leading whole bytes
(to match BYPASS), since it will believe they are the same and not do an
IR scan, failing (with "At least one TAP shouldn't be in BYPASS mode")
in the subsequent DR scan due to the TAP still being recorded as having
bypass set (and really having an instruction of either BYPASS or
IDCODE).

Parshintsev Anatoly f0bad430df rtos/hwthread: fix threadid generation
Looks like 7f2d3e2925 introduced a regression by incorrectly assigning
threads. The title of the commit message says that the intention was to
"derive threadid from SMP index", this is not what happens, however.
Instead threadid is assigned based on an index of all examined targets
in an SMP group.

This introduces two logical errors.

*Error 1*

Here is the code that assigns threads to harts:

```
foreach_smp_target(head, target->smp_targets) {
  struct target *curr = head->target;

  if (!target_was_examined(curr))
    continue;

  threadid_t tid = threads_found + 1;
  hwthread_fill_thread(rtos, curr, threads_found, tid);
```

Now, imagine a situation when we have two targets: `target.A` and
`target.B`.  Let's assume that `target.A` is NOT examined (it could be
under reset, for example).  Then, according to the algorithm when
assigning thread identifiers `target.B` will be assigned tid of 1. The
respected inferior on GDB side will be called `Thread 1`.

Now, imagine that `target.A` activates and succefully examined - OpenOCD
will re-assign thread identifiers. And now on GDB side `Thread 1` will
represent the state of `target.A`. Which is incorrect.

*Error 2*

The reverse mapping between `threadid` and targets does not take the
state of targets into account.

```
static struct target *
hwthread_find_thread(struct target *target, threadid_t thread_id)
...
  threadid_t tid = 1;
  foreach_smp_target(head, target->smp_targets) {
    if (thread_id == tid)
      head->target;
    ++tid;
  }
```

So the constructed mapping is incorrect. Since in example above
`Thread 1` will get mapped to `target.A`.

*Solution:*

It seems that threadids should be assigned based on position of the
thread in an smp group disregarding the target state.

Parshintsev Anatoly 7a70a28e6b target/riscv: do not emit warnings when a non-existent CSR is hidden
hide_csrs should not emit warnings on an attempt to hide non-exitents CSR.
hide_csrs funcitonality is intended to be used for scenarios when we don`t
want certain groups of registers to be available in GDB. Typically this is
needed to simplify integration with various IDE. In such scenarious it may
be impractical/unfeseable to figure out which register is present on a
target. So reporting a situation when a user wants to hide a non-existent
register creates way too much noise. This commit reduces severity of
relevant debug message to LOG_TARGET_DEBUG

This was pointed out by gcc. Presumably it's a newer warning. I doubt it
has any effect on anything.

Evgeniy Naydanov 5a8697b3cf target/riscv: manage triggers available to OpenOCD for internal use
Before the change, if the user wrote to any `tdata*` register, OpenOCD
would sometimes start to disable all the triggers (by writing zeroes to
`tdata1`) and re-enable them again (by witing all trigger registers to the
values read before for each `tselect` value), e.g. on `step`
(see `disable/enable_triggers()`).

There are a couple of issues with such approach:
1. RISC-V Debug Specification does not require custom register types
   to support re-enabling by such sequence of writes (e.g. some custom
   trigger type may require writing a custom CSR to enable it).
2. OpenOCD may still overwrite these triggers when a user asks to set a
   new WP.

This commit introduces `riscv reserve_trigger ...` command to explicitly
mark the triggers OpenOCD should not touch.

Such approach allows to separate management of custom triggers and
offload it onto the user (e.g. disable/enable such triggers by setting up
an event handler on `step`-related events).

Evgeniy Naydanov 6c021da8cc target/riscv: check `misa` value before reporting
Currently, during register file examination:
1. A read of an XPR is attempted via 64-bit abstract access.
2. If such a read fails (e.g. connection unstable) XLEN is assumed to be
   32.
3. Then `misa` is read. Since `misa` is a CSR and it may be only
   readable via program buffer, `s0` should be readable beforehand (at
   least some assumption about `xlen` should be made).
4. Before the commit, the `misa.mxl` field was not checked against
   `xlen`, therefore erroneous info may have been reported to the user.
   Moreover, the `examine()` would pass indicating no error at all.
5. After the commit, `misa.mxl` is checked against `xlen` value.
