[PULL,004/123] gdbstub: Use vaddr type for generic insert/remove_breakpoint() API

Commit Message

Philippe Mathieu-Daudé Feb. 27, 2023, 12:36 p.m. UTC

Both insert/remove_breakpoint() handlers are used in system and
user emulation. We can not use the 'hwaddr' type on user emulation,
we have to use 'vaddr' which is defined as "wide enough to contain
any #target_ulong virtual address".

gdbstub.c doesn't require to include "exec/hwaddr.h" anymore.
