Presently, we rely on gdb to restore break/watchpoints upon resuming
execution in arc_resume(). To match this behavior in absence of gdb
(more specifically, when handle_breakpoints is true), this patch
explicitly re-enables all breakpoints and watchpoints in arc_resume().
This has previously been committed to the Zephyr project's openocd repo
(see https://github.com/zephyrproject-rtos/openocd/pull/31).

By queuing multiple jtag transfers the connection speed between
JTAG-Host and JTAG-Hub is improved. This is due to much less
calls to OS functions. An improvement of about x30 has been
measured with ftdi-based jtag adapters
For this to work the JTAG-Host server needs to know if flow control
is enabled on the JTAG-Hub ports. This is possible with newer
JTAG-Hub/JtagCDC. For old JTAG-Hubs the queuing is not enabled so
this change is backwards compatible.

Some bitbang interfaces have no speed regulation and work as fast as
they can. Only the sequence of execuded commands is guaranteed but
not the timing. It works most of time with one exception: when the
JTAG_SLEEP command is executed, we expect that all previous commands
already finished so that the sleep interval is guaranteed.
For now there may be situations when the sleep time has passed but
previous commands are not actually executed.
This patch adds a flush command to the bitbang interface, connects it
to the existing implementation for remote_bitbang, and runs it when
the JTAG_SLEEP command is executed.

The original code supported ADIv5 only, just one SELECT register
with some reserved bits - the pseudo value DP_SELECT_INVALID was
just fine to indicate the DP SELECT register is in an unknown state.
Added ADIv6 support required DP SELECT and SELECT1 registers
without reserved bits. Therefore DP_SELECT_INVALID value became
reachable as a (fortunately not really used) ADIv6 AP ADDR.
JTAG DPBANKSEL setting support introduced with ADIv6 does not
honor DP_SELECT_INVALID correctly: required select value
gets compared to DP_SELECT_INVALID value and the most common zero
bank does not trigger DP SELECT write.
DP banked registers need just to set DP SELECT. ADIv6 AP register
addressing scheme may use both DP SELECT and SELECT1. This further
complicates using a single invalid value.
Moreover the difference how the SWD line reset influences
DPBANKSEL field between ADIv5 and ADIv6 deserves better handling
than setting select cache to zero and then to DP_SELECT_INVALID
in a very specific code positions.
Introduce bool flags indicating the validity of each SELECT
register and one SWD specific for DPBANKSEL field.
Use the latter to prevent selecting DP BANK before taking
the connection out of reset by reading DPIDR.
Treat DP SELECT and SELECT1 individually in ADIv6 64-bit mode.
Update comments to reflect the difference between ADIv5 and ADIv6
in SWD line reset.

Currently all Atmel CMSIS-DAP interfaces are assumed to have 512 byte
reports except for the mEDBG (found on Xplained Mini boards) and the nEDBG
(found on Curiosity Nano boards). This check is far from exaustive and it
results in some Microchip programmers (like the MPLAB Snap and PICkit 4)
not working correctly with OpenOCD.
Instead of assuming that Atmel programmers have 512 byte reports unless we
know otherwise, this commit flips the logic around. Only the older "third
generation" EDBG based programmers have 512 byte report sizes, and that 64
bytes will be more common in Microchip tools going forward.
The list of PIDs for 3rd generation Microchip programmers comes from
toolinfo.py from Microchip's pyedbglib.
This commit adds a more generic "quirks" list that will allow programmers
with unusual report sizes to be added easily in the future.
