Current code assumes all the GPIO signals are manipulated via a single

Fix the check instead of trying to handle additional GPIOs (available on
Raspberry Pi Compute Modules) as that would slow the driver down.

The main purpose of TCP server is to allow multiple clients to
connect and share the same physical stlink.
The commands RW MISC don't lock the communication between command
and answer, thus cannot prevent another client to break this
sequence. The commands are not supposed to be used in shared mode.
Prevent the use of RW MISC commands on a (possibly) shared TCP
backend.
This degrades the overall performance, but the shared mode already
adds its own overhead, so this is not really an issue.

The stlink commands for buffer read/write carry the associated CSW
value that has to be used. We can dequeue any CSW write request
and add the CSW in the following buffer read/write.
In preparation to next patch that uses stlink commands misc-rw
(commands that don't handle CSW value), let's dequeue only those
CSW write that don't change csw_default.
Keep a local cache of last csw_default.
Tag the queued CSW writes that change csw_default.
Dequeue only the un-tagged CSW writes.
On buffer read/write commands, limiting the dequeued CSW write
surely adds a performance penalty. But csw_default is not changed
often so the penalty is not significant.

By using the stlink commands for memory read write we can gain
some performance, but only when TAR and/or CSW are changed.
During long transfers with constant CSW and TAR auto-incremented
there is no gain, since the same amount of USB/TCP packet is used.
Plus, by dropping ADIv5 packed transfers the performance is lower
on 8 and 16 bits transfers.
This changes opens the opportunity for collapsing memory burst
accesses in a single stlink USB/TCP packet.
Initialize the values of enum queue_cmd to easily extract the word
size through a macro, even if this is not used here.

At low clock speeds, no issue is observed when the poll

The status polls are done on the target for efficiency,

an error after the reset command.
Ignore the error detected by 'dap init' and proceed executing the
handler. The error in 'dap init' will force a reconnect during the
following 'dap apid', restoring the SWD functionality.
