It is a common requirement to automatically execute some command
after "init".
This can be achieved, either in scripts or through OpenOCD command
line, by explicitly calling "init" followed by the commands.
But this approach fails if the request for post-init commands is
spread across configuration files; only one of the files can split
pre-init and post-init status by calling "init".
The common workaround is to "rename" the command "init" and
replace it with a TCL proc that calls the original "init" and the
post-init commands. E.g. in Zephyr script [1].
To simplify and formalize the post-init execution, use a TCL list
that contains the list of commands to be executed. Every script
can contribute adding new commands, e.g. using "lappend".
In the same way, formalize the pre-shutdown execution with a TCL
list of user commands to be executed before OpenOCD exit.
Document them and add trivial examples.
Drop from documentation the suggestion to rename "shutdown".

Current implementation for gdb remote monitor command uses the
command_run_line() to execute the command.
While command_run_line() has several advantages, it unfortunately
hides the error codes and outputs the result of the command
through LOG_USER(), which is not what gdb requires. See 'qRcmd' in
https://sourceware.org/gdb/onlinedocs/gdb/General-Query-Packets.html
Replace command_run_line() with Jim_EvalObj() and parse the output
to provide the proper result to gdb.
Can be tested by defining in OpenOCD:
proc a {} {return hello}
proc b {} {return -code 4}
proc c {} {return -code 4 "This is an error!"}
then by executing in gdb console:
monitor a
monitor b
monitor c

GDB client cannot always display generic messages from OpenOCD.

OpenOCD output to GDB.
While this is a nice stress test for log_{add,remove}_callback(),
it is also a waste of computational resources that could impact
the speed of OpenOCD during GDB user interactions.
Add a connection-level flag to enable/disable the log callback and
simply change the flag instead of adding/removing the callback.
Use an enum for the flag instead of a bool. This improves code

that doesn't apply on current versions.
Remove the obsolete hacks to suppress the warnings.

The existing implementation blocks in select() for a fixed amount of
time. This change tracks when the next event (likely poll()) wants to be
run, and uses a shorter timeout in select() if necessary.
Also track all these timeouts using milliseconds as returned by
timeval_ms() instead of `struct timeval` to simplify the code.
This feature is helpful if poll() wants to do something like sample PCs
or memory values for basically the entire time that otherwise OpenOCD
would be hung in select(). See
https://github.com/riscv/riscv-openocd/pull/541 for an example of that.
The RISC-V code using this change will be upstreamed some day, too.
