[PATCH v3 0/3] gdbstub: avoid untimely stop-reply msgs

[Matheus Tavares Bernardino <quic_mathbern@quicinc.com>]

This series limits gdbstub to send stop-reply packets only as a reply to
commands that accept them, following the RSP specification.

Changes since v2[1]:

- Replaced char buffer with boolean at struct GDBState.
- Covered other functions that might send stop-reply packets.
- Added test.

Note: I was able to run the added test previously I make sure it passes
after the change, but after rebasing onto master, `make check-tcg` is
giving me the following error (this also happens at the tip of master in
my machine):

	qemu: could not load PC BIOS 'bios-256k.bin'

Perhaps I'm doing something wrong at compilation/testing?
