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
interface is required in order to run OpenOCD in JTAG mode again.
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()

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.

Fix Semihosting FileIO for targets using vcont packet

We need to update target last run control information to decide resumption. This
was not being done for vcont packets.

flash_bank structure of 'virtual' flash driver is a full copy of
the master flash_bank structure including bank->sectors and
bank->prot_blocks pointers. These pointers point to memory
locations allocated by the master driver and thus master driver
is responsible for deallocating them.
Do not free bank->sectors and bank->prot_blocks of 'virtual'

Rework/update ARM semihosting
In 2016, ARM released the second edition of the semihosting specs
("Semihosting for AArch32 and AArch64"), adding support for 64-bits.
To ease the reuse of the semihosting logic for other platforms
(like RISC-V), the semihosting code was isolated from the ARM
target and updated to the latest specs.
The new code is already in use since January (in GNU MCU Eclipse
OpenOCD) and no problems were reported, neither for ARM nor for
RISC-V targets, after more than 7K downloads.

target/cortex_m: allow setting the type of a breakpoint
Cortex-M target used 'auto_bp_type' mode. The requested type

vice versa. External flash (parallel or QSPI) is usually mapped above
code memory area. Cortex-M7 ITCM RAM is mapped at 0. Kinetis

flash/nor: handle flash write alignment/padding in the infrastructure
Most of flash drivers have to ensure proper flash write block alignment
and padding. As there was no support for it in the flash infrastructure,
each driver does it its own way. Sometimes this part of code is not properly
tested and contains bugs.
flash_write(_unlock) joins all image sections targeted to one flash bank
using padded areas as a glue. This solves alignment problems on section
boundaries but imposes other problems.
Introduce new flash bank parameters write_start_alignment,
write_end_alignment and minimal_write_gap.
New flash drivers can just properly set these values instead of handling
alignment by its own.
Adapt infrastructure (namely flash_write_unlock(), handle_flash_fill_command()
and handle_flash_write_bank_command()) to prepare write data padded
to an alignment required by the flash bank.
Rework flash_write_unlock() to discontinue write block when the gap
between sections is bigger than minimum specified in minimal_write_gap.
minimal_write_gap is set to one sector by default.

target, flash: prepare infrastructure for multi-block blank check
'flash erase_check' command runs a check algorithm on a target
if possible. The algorithm is run repeatedly for each flash sector.
Unfortunately every start and stop of the algorithm impose not negligible
overhead.
In practice it means checking is faster than plain read only for
sectors of size approx 4 kByte or bigger. And checking sectors
as short as 512 bytes runs approx 4 times slower than plain read.
The patch changes API call target_blank_check_memory() and related
to take an array of sectors (or arbitrary memory blocks).
Changes in target-specific checking routines are kept minimal.
They use only the first block from the array and process it by
the unchanged algorithm.
default_flash_blank_check() routine repeats target_blank_check_memory()
until all blocks are checked, so it works with both multi-block
and single-block based checkers.
