We unfortunately handle the checking of packet acknowledgement

behind gdb_got_immediate_ack with a stub for softmmu.

The process was pretty similar to the softmmu move except we take the
time to split stuff between user.c and user-target.c to avoid as much
target specific compilation as possible. We also start to make use of
our shiny new header scheme so the user-only helpers can be included
without the rest of the exec/gsbstub.h cruft.
As before we split some functions into user and softmmu versions

- move shared structures to internals.h
- splitting some functions into user and softmmu versions
- fixing a few casting issues to keep softmmu common

These will be needed from multiple places in the code. They are
declared as inline so move to the header and fix up to modern coding
style.
The only other place that messes with hex stuff at the moment is the
URI handling in utils but that would be more code churn so leave for

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.
