Signal handlers currently violate both C language and POSIX requirements:
1. To avoid undefined behavior (UB), variables accessed or modified by
signal handlers be of atomic lock-free type.
2. The respected variables should be marked as volatile.
3. Signal handlers may only call a very limited subset of standard
library functions.
4. Additionally, POSIX restricts signal handlers to signal-safe
functions.
This patch addresses the first two issues by changing the type of global
variables that are accessed inside signal handler to `sig_atomic_t` and
adding `volatile` qualifiers.
Items 3 and 4 must be handled separately but are outside the scope of
this change.

JimTcl has been so far quite comfortable with new commands that
return error codes not supported by JimTcl itself.
This has been exploited by OpenOCD, allowing the OpenOCD commands
to return OpenOCD error codes mixed with JimTcl error code.
With the change [1] merged in JimTcl branch 'master' for 0.84, any
negative value returned by a command gets interpreted as a syntax
error detected at runtime by the command itself; JimTcl dumps the
correct syntax and returns a valid JimTcl error code that replaces
the negative value.
Since all OpenOCD error codes are negative values, they are all
taken as syntax errors by the new JimTcl. E.g.:
openocd -c exit
dumps
wrong # args: should be "exit ..."
Actually OpenOCD does not need the OpenOCD error code from the
commands, with the exception of the codes:
[a] ERROR_COMMAND_SYNTAX_ERROR, used internally by the command
dispatcher, before returning to JimTcl;
[b] ERROR_COMMAND_CLOSE_CONNECTION, to alert the telnet server
that the current connection should be closed.
With [a] already used internally, only [b] needs to be propagated
through JimTcl and back to the OpenOCD caller.
Map the OpenOCD error code ERROR_COMMAND_CLOSE_CONNECTION to the
existing JimTcl error code JIM_EXIT, originally used only by
JimTcl 'exit' command.
Detect JIM_EXIT in command_run_line() and return to the caller the
original ERROR_COMMAND_CLOSE_CONNECTION.
Let exec_command(), and also its caller jim_command_dispatch(),
to only return JimTcl error codes. Rename it to report the change.
Modify the test suite as now a syntax error does not returns -601
anymore.
While there, drop the association key "retval" as it's not used.
Note: after this change there is no real need to replace the
JimTcl command 'exit' with the OpenOCD version as both produce the
same result. But I prefer keeping the code as is to mask any
future change in the related JimTcl code.

CH347 chip firmware probably does not service USB poll/requests
from the host during processing of SWD packet. If the processing
takes longer than approx 8 ms, USB host disconnects the adapter
from the bus as if it were dead.
To avoid disconnect, compute approximate processing time
of SWD transactions and flush the queue if the total time
gets over the limit (use 7 ms to keep some safety margin).
Allow ch347_swd_send_idle() to split the requested delay
to more partial sequences. It prevents USB disconnect at beginning
of target examine, when memaccess 255 clk is used.
Also memaccess > 255 clk is now possible.
Set the maximal divisor to fit the longest ADI sequence
into 7 ms processing time.
