drivers/cmsis-dap: speed up sending multiple HID requests

The performance of CMSIS-DAP in long data transfers was improved substantially in
ef02b69b14d133b061217a91add5a028a77e86bc. But it not as good as some
other USB/MCU based adapters. Using HID and therefore interrupt endpoint
is slower than USB bulk transfer.

CMSIS-DAP adapter implements multiple HID buffer handling and OpenOCD already
reads number of buffers from info command.

This change adds capability to sumbit more than one HID requests before
driver waits for a HID response. This scenario is used for long transfers only.
Results show about double speed on USB FS and ~140% speed on USB HS:

target/cortex_a: fix temporary breakpoint during step

Commit c8926d14579528bfcead1e179baf7cb846513db4 introduces the
context and hybrid breakpoint types beside existing SW and HW
types. The new field "asid" is non-zero only for these new types.

The commit above did not properly initialize "asid" to 0 for a
temporarily HW breakpoint used during single step. This causes
cortex_a_unset_breakpoint() to identify this breakpoint as of
type "hybrid".

Identified through valgrind error:
Conditional jump or move depends on uninitialised value(s)
Actually valgrind triggers a total of 10 messages about use of
uninitialized variables, but they are all caused by the first
conditional jump bases on "asid != 0".

Fixed by initializing "asid" to 0 in cortex_a_step().

target/arm_adi_v5: fix sync CSW cache on apreg write

Commit 0057c71ab6b81d0679b232318fc5f84b4becc471 updates the OpenOCD
cached values of CSW and TAR registers if these registers are modified
by an apreg command.
The condition to force the update of CSW cache is incorrect and it will
erase the default CSW value.
Moreover, calling mem_ap_setup_csw() does not honor the value requested
in the apreg command because such value is incorrectly bitwise or-ed
with csw_default.

Fix it by updating csw_value, instead of erasing csw_default, and writing
directly in CSW register the new value from the command line.

target/cortex_a: poll all targets in SMP node after halt

The periodic poll scans all the targets in the same order they
have been declared in the configuration file.
When one target in a SMP node halts, the transition is detected
in the following poll and this triggers a halt request to all the
other cores of the SMP node.
The targets that will be polled afterwards will be identified as
"halted", but the targets already scanned will remain as
"running" until the next periodic poll.
This creates a race condition with GDB; GDB sets the breakpoints
when runs the target and removes them as soon as the target is
halted. When it receives the halt event, it starts removing the
breakpoints and fails on the targets that are still reported as
"running".

Fixed by polling all the targets in the SMP node before informing
GDB about the halt event.
This implementation is almost copy/paste from the one in aarch64.

gdb_server: add per target option "-gdb-port"

The argument passed to global config command "gdb_port" is usually,
but not always, a TCP port number. In case of multiple targets, this
numeric value is used as the first port of a set of consecutive TCP
ports assigned one per target.
If the argument is not a numeric value (e.g. "pipe", "disabled", ...)
then incrementing it for the next target has no sense.

Add the option "-gdb-port number" to the commands "target create" and
"$target_name configure" to override, for the specific target, the
general global configuration.

This permits to use a per target "-gdb-port disabled", when no gdb
port is required for that specific target.

It also makes possible to choose a custom TCP port number for each
target, overriding the usual sequence of consecutive port numbers.

apid, making redundant printing it by apsel too.

server: explicitly call "shutdown" when catch CTRL-C or a signal

Every TCL command can be renamed (or deleted) and then replaced by
a TCL proc that has the same name of the original TCL command.
This can be used either to completely replace an existing command
or to wrap the original command to extend its functionality.
This applies also to the OpenOCD command "shutdown" and can be
useful, for example, to set back some default value to the target
before quitting OpenOCD.
E.g. (TCL code):
rename shutdown original_shutdown
proc shutdown {} {
puts "This is my implementation of shutdown"
# my own stuff before exit OpenOCD
original_shutdown
}

Unfortunately, sending a signal (or pressing CTRL-C) to terminate
OpenOCD doesn't trigger calling the original "shutdown" command
nor its (eventual) replacement.

Detect if the main loop is terminated by an external signal and
in such case execute explicitly the command "shutdown".
Replace with enum the magic numbers assumed by "shutdown_openocd".

Please notice that it's possible to write a custom "shutdown" TCL
proc that does not call the original "shutdown" command. This is
useful, for example, to prevent the user to quit OpenOCD by typing
"shutdown" in the telnet session.
Such case will not prevent OpenOCD to terminate when receiving a
signal; OpenOCD will quit after executing the custom "shutdown"
command.

arm_adi_v5: put SWJ-DP back to JTAG mode at exit

When SWD mode is used, current OpenOCD code left the SWJ-DP in
SWD mode at exit. Also, current code is unable to switch back the
SWJ-DP in JTAG at next run, thus a power cycle of both target and

Put the SWJ-DP back to JTAG mode before exit from OpenOCD.

Use switch_seq(SWD_TO_JTAG) instead of dap_to_jtag(), because the
latter is not implemented on some interfaces. This is aligned
with the use of switch_seq(JTAG_TO_SWD) in swd_connect().

armv7a: read ttbcr and ttb0/1 at every entry in debug state

Commit bfc5c764df145f68835543119865eabe462e19c2 avoids reading
ttbcr and ttb0/1 at every virt2phys translation by caching them,
and it updates the cached values in armv7a_arch_state().
But the purpose of any (*arch_state)() method, thus including
armv7a_arch_state(), is to only print out and inform the user
about some architecture specific status.
Moreover, to reduce the verbosity during a GDB session, the
method (*arch_state)() is not executed anymore at debug state
entry (check use of target->verbose_halt_msg in src/openocd.c),
thus the state of translation table gets out-of-sync triggering
Error: Address translation failure
or even using a wrong address in the memory R/W operation.

In addition, the commit above breaks the case of armv7r by
calling armv7a_read_ttbcr() unconditionally.

Fixed by moving in cortex_a_post_debug_entry() the call to
armv7a_read_ttbcr() on armv7a case only.
Remove the call to armv7a_read_ttbcr() in armv7a_identify_cache()
since it is (conditionally) called only in the same procedure
cortex_a_post_debug_entry().

server: Improve signal handling under Linux

Commit 5087a955 added custom signal handlers for the openocd
server process.

Before this commit, when openocd is run as a background process
having the same controlling terminal as gdb, Control-C would be
handled by gdb to stop target execution and return to the gdb prompt.

However, after commit 5087a955, the SIGINT caused by pressing
Control-C also terminates openocd, effectively crashing the
debugging session.  The only way to avoid this is run openocd in
a different controling terminal or to detach openocd from its
controlling terminal,
thus losing all job control for the openocd process.

This patch improves the server's handling of POSIX signals:
1) Keyboard generated signals (INT and QUIT) are ignored
   when server process has is no controlling terminal.
2) SIGHUP and SIGPIPE are handled to ensure that .quit functions
   for each interface are called if user's logs out of X
   session or there is a network failure.

SIG_INT & SIG_QUIT still stop openocd
when it is running in the foreground.
