a35712a85c server: shutdown command should lead to exit without evaluating the rest
Currently

openocd -c "echo a1; shutdown; echo a2"

outputs both "a1" and "a2" and only then shuts down. This patch fixes
it by making shutdown command throw an exception, so unless it's
caught the shutdown will behave as expected.

d99efc9076 gdb_server: do not copy feature names for tdesc generation
We always have feature names defined by string literals and the
standard guarantees static storage duration for them. Hence, there's
no need duplicating and then freeing them.

Valgrind-tested.

da0d1e374b gdb_server: fix memory leaks in users of get_reg_features_list()
v4:
- changed first line of commit message
v3:
- added extra LOG_ERROR() message
v2:
- Added missing "goto error"
- free also the on extra element of features[]

In contrast to target_get_gdb_reg_list(), the list returned by
get_reg_features_list() consists of items which are itself
malloc'ed.
--> Free the list items prior freeing the list itself.

Additionally:
- gdb_generate_target_description():
  o Do error handling similar as gdb_get_target_description_chunk() does.
- gdb_get_target_description_chunk()
  o **features must be initialised prior an "goto error" can happen

e4125d136c gdb_server: Fix confusing warning when entering noack mode
Comment in gdb_server code mistakenly attributed constant warnings
about unexpected acknowledgement to the ACK packet sent by GDB when
establishing connection. However that is not the case, OpenOCD
gdb_server is handling this packet correctly without an warnings. This
warning instead was caused by the ACK packet which GDB sends right after
going into noack mode. Because OpenOCD gdb_server is already in noack
mode at this state, it emits warning about it. This is a documented GDB
behaviour
(https://sourceware.org/gdb/onlinedocs/gdb/Packet-Acknowledgment.html)
so there is no reason to scare users with warnings in this case.

This patch basically introduces two-level noack mode: after receiving
QStartNoAckMode gdb_server will set noack_mode to 1, then it will
receive this last ACK packet, but instead of printing a warning,
noack_mode will be increased to 2. Should there be any other ACK packets
after that, they will be properly reported by warning. All other code
that relies on noack_mode checks it for "!= 0", so there will be no
difference if it is 1 or 2.

5175f8be33 fix flash bank auto_probe() fail with multiple targets
get_flash_bank_by_addr() iterates through all flash banks
trying to auto_probe() every bank, even if bank can belongs to
target other than requested, and this other target can be
in non-halted state, which leads to error message and
operation abort.
  Same situation in gdb_new_connection() and gdb_memory_map():
get_flash_bank_by_num() tries to auto_probe() requested bank,
so first get bank by get_flash_bank_by_num_noprobe(), check
if it belongs to current connection's target and skip
get_flash_bank_by_num() (actually autoprobing) if not.

517ba0690d Clean up const usage to avoid excessive casting
Don't use const on pointers that hold heap allocated data, because that

Do use const on pointer parameters or fields that needn't be modified.

Remove pointer casts that are no longer needed after fixing the constness.

b8a23f1c43 gdb_server: Do not set gdb_con->sync to true for new connections
In GDB connected to OpenOCD there is a command "monitor gdb_sync" which makes
next stepi command to be ignored while GDB still will get an updated target
state. This command sets gdb_connection->sync field to true to notify that stepi
should be ignored. This field is set to true for all new connection and is set
to false after first "continue" command. However if first resume command is
stepi/nexti then it will be ignored and result will confuse GDB client, it will
report that target received signal SIGINT. This patch sets this field to false
for new connections, thus stepi/nexti will work properly when it is a first
resume command.
