This patch fixes the handling of errno by setting the sys_errn
only if error has actually occurred during the semihosting call.
It also fixes few issues where error was not set in the first place.

The current cJTAG to JTAG switching commands for TI chips are not
particularly reliable, especially on chips with accurate timing.
On a Raspberry Pi the existing sequence has (depending on cabling and
chip) a ~50% chance of working, on a much better-behaved FT2232H
it doesn't manage to enable full JTAG at all.
This change runs a bunch of test-idle cycles before actually attempting
to switch to full JTAG. This makes the switch reliable even at high
clock speeds (>100kHz) and from precise sources like the FT2232H.

The old implementation of gdb socket error handling
in the gdb_get_char_inner() differs between Windows and *nix
platforms. This patch simplifies it by using an existing
function log_socket_error() which handles most of the platform
specific things. It also provides better error messages.

This patch adds support for the NXP QN908x family of Bluetooth
microcontrollers, such as the QN9080. This chip features a Cortex-M4F
with 512 KiB of flash on all the available versions, although the
documentation suggests that there might be 256 kB versions as well.
The initial support allows to read, erase and write the whole user flash
area. Three new sub-commands under the new "qn908x" command are added
in this patch as well: disable_wdog to disabled the watchdog,
mass_erase to perform a mass erase and allow_brick to allow programming
images that disable the SWD interface.
Disabling the watchdog is required after a "reset halt" in order to run
the CRC algorithm from RAM when verifying the chip. However, this is not
done automatically on probing or other initialization since disabling
the watchdog might interfere with debugging real applications.
The "mass_erase" command allows to erase the whole flash without
probing it, since in some scenarios the chip can be locked such that no
flash or ram can be accessed from the SWD interface, allowing only to
run a mass_erase to be able to flash the program.
The flashing process allows to compute a checksum, similar to the
lpc2000 driver "calc_checksum" but done over a different region of the
memory. This checksum is required to be present for the QN908x
bootloader ROM to boot, and otherwise is useless. As with the lpc2000
design, verification when using "calc_checksum" is expected to fail if
the checksum was not valid in the image being verified.
This was manually tested on a QN9080, including the scan-view,
AddressSanitizer/UBSan and test coverage configurations.

Clang is unable to fully track the content of the array
write_buffer[] and incorrectly complains that it could contain
some uninitialized value.
To help clang to track the execution flow, rewrite the handling of
the buffer by using simpler indexing and by moving away cmd_byte
from the first buffer's element to the variable cmd_byte.
While there:
- fix the error codes returned while parsing the command line and
- use directly command_print_sameline() instead of passing through
intermediate buffers.
