We currently fail the transfer when issuing more than 255 transactions
at once, e.g.
> read_memory 0x10000000 32 256
CMSIS-DAP transfer count mismatch: expected 257, got 1
This is because the protocol only supports 255 transactions per packet
(65535 for block transactions), and as a result we truncate the
transaction count when assembling the packet. Fix it by running the
queue when we hit the limit.

The OpenOCD commands produce their TCL text result through the
pair command_print() and command_print_sameline().
The latter is used to concatenate output in a single line.
At the end of a sequence of command_print(), the last LF is taken
as part of the command result, while it is not always needed, and
it is even annoying when the output of two commands needs to be
concatenate in a single line.
Using command_print_sameline() in place of the last call to
command_print() would solve the problem but it's quite expensive
in term of coding to fix all the existing commands.
Drop the last LF, if present.
Commands that would specifically need a LF as last char, can add
an extra LF at the end of the output.
Document this behavior in command.h.

A bunch of new SPI flash (Adesto, Cypress, XTX Tech, mainly octal)
IDs and SPI FRAM (Infineon) IDs added. Backward compatible change
of ID interpretation: The previously unused 4th byte now acts
as continuation code (0x7F) count for manufacturer id, cf.
JEDEC JEP106BC. Currently this affects only some recent octal flash
and FRAM devices, which are only supported by stmqspi and cmspi
flash drivers.

Long ago jim_nvp was part of jimtcl. When jimtcl dropped it,
OpenOCD kept copy of it in its code base. Current code of jim_nvp
is still related with jimtcl data types and functions.
With the target of better isolating OpenOCD code from jimtcl,
create a new file nvp.c that re-proposes only the core of the old
jim_nvp, dropping any link with jimtcl and removing the string
'jim' either from the filename and from the code.
Keep the same license from the old code, as the new files are
clearly derived from it.

After setting adapter speed to some values, the driver
shows the real speed little bit higher.
Although it does not impose a problem from technical point
of view because the difference is smaller than usual speed error,
it looks at least strange to the user. The documentation reads
that real frequency should be same or lower than requested.
Use proper rounding in speed -> delay and delay -> speed
conversions.

bitbang_swd_exchange(rnw=true,...) calls bitbang_interface->swd_write()
with swdio clamped to 0.
bitbang_swd_write_reg() reads 1 turnaround bit, 3 ack bits
and 1 turnaround by one call to bitbang_swd_exchange()
and then switches SWDIO to output.
AFAIK all bitbang interfaces switch SWDIO GPIO direction immediately
in bitbang_interface->swdio_drive().
The GPIO now drives SWDIO line to the value stored in the output register
which is always zero from previous bitbang_swd_exchange(rnw=true,...).
In case the following data bit (bit 0) is 1 we can observe a glitch
on SWDIO:
_____ out 1 ____
HiZ/pull-up ----\ /
\ /
\______ out 0 ______/
swdio_drive(true) swd_write(0,1)
The glitch fortunately takes place far enough from SWCLK rising edge
where SWDIO is sampled by the target, so I believe it is harmless
except some corner cases where the reflected wave is delayed on long
line.
Anyway keeping electrical signals glitch free is a good practice.
To keep performance penalty minimal, pre-write the first data
bit to SWDIO GPIO output buffer while clocking the turnaround bit.
Following swdio_drive(true) outputs the pre-written value
and the same value is rewritten by the next swd_write()
instead of glitching SWDIO.
