This was used to track which hart a given operation must apply to. But
we already have a target associated with each operation, and from there
we can find the desired hart id. dm013_info_t already tracks
current_hartid (meaning which hart ID is currently selected by the DM).
This makes the code simpler to understand. Also it turns out we don't
need to make sure the correct hart ID is currently selected because
there are only a few real entry points.

According to RISC-V External Debug Support Version 0.13.2 (paragraph
3.12.6), cmderr field contains a valid value only if busy is 0, so it is
incorrect to analize it on timeout.
Requested in https://review.openocd.org/c/openocd/+/6964.
I'm making the change here so I have a chance to test it properly before
pushing it upstream.
A nice effect of this change is that we avoid some unnecessary polling
early on when gdb is connecting and we would poll once every time we
send gdb a qXfer packet.

Otherwise OpenOCD simply doesn't work without giving any indication why.

* Don't read dmcontrol to set hartsel
We already know what dmcontrol should be. This addresses a long-standing
TODO. In a toy test, this reduced the number of scans by 10+%. (Most of
those are probably in poll(), so don't actually affect perceived
performance.)

If range's upper bound was equal to 2^64 or the range was wrapping around 0
(which is perfectly legal), writes were not performed due to riscv_addr_t
overflow.
This one doesn't have the license in there, which means now it's
acceptable to GPLv2 again.

The segfault could be triggered if:
- At least one target failed to get examined (therefore does not have the
register cache set up yet),
- and "reset" TCL command was issued, which internally tries to
invalidate the register cache.
Minor cleanup: "registers_initialized" member removed from riscv_info_t
because it is not used anywhere.

Commit 5ebb1bdea1 ("server/gdb: fix return of gdb remote monitor
command") replaces the call to command_run_line() with call to
Jim_EvalObj() but does not properly set the "context".
In multi-target environment, his can cause the erroneously
execution of the command on the wrong target.
Copy from the code in command_run_line() the proper setup before
executing Jim_EvalObj().
