We unfortunately handle the checking of packet acknowledgement
differently for user and softmmu modes. Abstract the user mode stuff
behind gdb_got_immediate_ack with a stub for softmmu.

We don't really need a table for mapping two symbols.

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

This is mostly code motion but a number of things needed to be done
for this minimal patch set:
- move shared structures to internals.h
- splitting some functions into user and softmmu versions
- fixing a few casting issues to keep softmmu common
More CONFIG_USER_ONLY stuff will be handled in a following patches.

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.

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.

This removes the final hard coding of kvm_enabled() in gdbstub and
moves the check to an AccelOps.

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.
