OpenOCD currently uses improper "fence" instruction:
"FENCE" opcode with empty predecessor and successor sets.
Such instruction has no effect and is reserved for future use
as a HINT instruction (RISC-V Unprivileged ISA spec V20191213,
section 2.9).
This patch fixes it by using the proper "fence rw,rw"
instruction.

rp2040-core0.cfg configuration file was intended for a special adapter
which selects a SWD multidrop target on its own. This means
that rp2040-core0.cfg is totally unusable with a standard SWD
adapter. The file was marked as deprecated in 0.12 release.
The reworked rp2040.cfg can be restricted to use just one core:
openocd ... -c 'set USE_CORE 0' -f target/rp2040.cfg
Remove the obsoleted config.

Cortex-M support for SMP multicore targets.
This SMP implementation unlike older ones does not act
on the first halted target found. It polls targets
until a SMP group is finished and stores eventual
'halted' events instead of emitting them. As soon as polling
of a group is done, poll proceeds with SMP related tasks.
This approach improves detection of a reason why debug
stopped - a correct reason is detected for all targets,
not only for the first found.
Drawback: SMP target group should be defined in the same
order as the targets were defined.
Obsolete gdb 'J' packet/smp_gdb command core switching is not implemented,
use with rtos hwthread.
Only one core is resumed if debug_execution is requested.

When pointer authentication is enabled, some upper bits of the link
register (LR[63:VA_SIZE]) are used to store a signature. Therefore, GDB
need to remove the signature to get backtraces.
GDB has support of pointer authentication. When pointer authenticaion is
enabled, GDB requests 8-bytes mask to the target to remove the
signature. mask[63:VA_SIZE] should be all set and mask[VA_SIZE-1:0]
should be all cleared. GDB removes the signature by addr&~mask or
addr|mask.
I added a feature to provide the mask for pointer authentication.

Extended feature. This is a large patch, but is self-contained to the
eCos support and does not affect any other openocd functionality. It
does NOT affect existing eCos RTOS plugin users where their
applications do not provide the extended symbolic helper
information. If the helper symbols are not available the rtos support
code will behave as before. This "dynamic" functionality is *required*
because eCos does NOT have a fixed/hardwired, known, layout for the
thread descriptor structure. The per-application build eCos
configuration can affect the shape of the thread descriptor structure
(field presence, and hence offsets of subsequent fields) such that
constant values cannot be used to consistently interpret all possible
eCos application configurations. For historical reasons, there is not
yet a consistent namespace for the helper symbols across eCos HALs
hence the support is currently limited to specific architectures
(Cortex-M and ARM/Cortex-A). No new Clang analyser warnings are raised
by this changeset.

any real improvement since 2013.
It has been hard to keep them aligned during the evolution of
OpenOCD code, with no way for maintainers to really check if they

No real documentation is present for them in OpenOCD.
The nds32 code triggers ~50 errors/warnings with scan-build.
The arch nds32 has been dropped from Linux kernel v5.18-rc1.
For all the reasons above, this code has been deprecated with

libjaylink was integrated into OpenOCD as a Git submodule, because at
that time there was no official release and no packages for it.
Today there are libjaylink packages for most popular distributions [1].
Removing libjaylink from OpenOCD reduces build complexity in both
projects and makes them more flexible with respect to the build system,
for example.
Disable the libjaylink submodule by default and announce it as
deprecated feature that will be removed in the future. This gives
package maintainers time to package libjaylink if not already done.

This patch fixes two corner-cases of finding RTT control block.
The first one is when there was a partial match (even single byte) at
the end of loaded buffer (uint8_t buf[1024]), but this was not part of
full match. In that case `cb_offset` was not updated correctly and the
returned `*address` was lower by the legth of the partial match. In case
of searched 'SEGGER RTT' (the default control block ID) string, it was
enough to match `buf[1023] == 'S'`, which is quite likely to happen, and
the `*address` was offset by 1 (e.g. it was 0x20000fff instead of
0x20010000).
Updating (or even maintaining) `cb_offset` is not needed, as start
address of control block can be calculated based on memory address that
was loaded into `uint8_t buf[1024]`, the offset within this buffer and
the length of expected string.
The second issue is when control block is prepended with a byte that
matches first ID character, e.g. there is `SEGGER RTT` control block ID
is prepended by another `S`, making memory contents be `SSEGGER RTT`. In
that case there was no match found.
Fix that issue by making sure that tested byte is always compared with
first byte of expected control block ID.
While at it, change names of local variables to better describe their
meaning.
