Replace the FSF boilerplate with the SPDX tag.
The SPDX tag on files *.c is incorrect, as it should use the C99
single line comment using '//'. But current checkpatch doesn't
allow C99 comments, so keep using standard C comments, by now.

The array is partially initialized with buf_set_u32(,5,32,), then
the rest of the array is read from SWD.
But scan-build report the array to have garbage content after the
initialization, due to the offset of 5 bit that only inits part of
the first byte.
Silence the false positive from scan-build by initializing the
array.

Ignore ack received after DP_TARGETSEL write to prevent false error.
This change also fixes a bug:
Received ACK FAULT or JUNK value were incorrectly stored to queued_retval
and later used as bitbang_swd_run_queue() error return.
Use LOG_ERROR for parity mismatch.

The split in OpenOCD between SWD and JTAG has been already fully
implemented. The bitbang driver still keeps a single API write()
to drive the output lines.
Introduce a new SWD specific API swd_write().
Move the existing SWD bitbang drivers to the new API by extracting
the available conditional implementation.
Cleanup some function prototype.
Remove the now unused global swd_mode, handled implicitly.
Rename bitbang_exchange() as bitbang_swd_exchange() to track its
scope for SWD only.

Previously for every bit scanned OpenOCD would write the bit, wait for
that bit to be scanned, and then read the result. This involves at least
2 context switches. Most of the time the next bit scanned does not
depend on the last bit we read, so with a buffer we now write a bunch of
bits to be scanned all at once, and then we wait for them all to be
scanned and have a result.
This reduces the time for one testcase where OpenOCD connects to a
simulator from 12.30s to 5.35s!
Running all our tests went from 13m13s to 3m55s.

Making the SWD driver aware of the DAP that controls it is a layering
violation.
The only usage for the DAP pointer is to store the number of idle cycles
the AP may need to avoid WAITs. Replace the DAP pointer with a cycle
count hint instead to avoid future misuse.
