2023-03-07gdbstub: define separate user/system structuresAlex Bennée1-41/+53
In preparation for moving user/softmmu specific bits from the main gdbstub file we need to separate the connection details into a user/softmmu state. As these will eventually be defined in their own files we move them out of the common GDBState structure.

Otherwise checkpatch will throw a hissy fit on the later patches that split this function up.

2023-03-07gdbstub: fix-up copyright and license filesAlex Bennée2-2/+4
When I started splitting gdbstub apart I was a little too boilerplate with my file headers. Fix up to carry over Fabrice's copyright and the LGPL license header.

2023-02-27replay: Extract core API to 'exec/replay-core.h'Philippe Mathieu-Daudé1-1/+1
replay API is used deeply within TCG common code (common to user and system emulation). Unfortunately "sysemu/replay.h" requires some QAPI headers for few system-specific declarations, example: void replay_input_event(QemuConsole *src, InputEvent *evt); Since commit c2651c0eaa ("qapi/meson: Restrict UI module to system emulation and tools") the QAPI header defining the InputEvent is not generated anymore. To keep it simple, extract the 'core' replay prototypes to a new "exec/replay-core.h" header which we include in the TCG code that doesn't need the rest of the replay API.

2023-02-27gdbstub: Use vaddr type for generic insert/remove_breakpoint() APIPhilippe Mathieu-Daudé4-9/+8
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.

2022-10-06gdbstub: move breakpoint logic to accel opsAlex Bennée5-118/+137
As HW virtualization requires specific support to handle breakpoints lets push out special casing out of the core gdbstub code and into AccelOpsClass. This will make it easier to add other accelerator support and reduces some of the stub shenanigans.

2022-10-06gdbstub: move sstep flags probing into AccelClassAlex Bennée1-18/+4
The support of single-stepping is very much dependent on support from the accelerator we are using. To avoid special casing in gdbstub move the probing out to an AccelClass function so future accelerators can put their code there.
