Alex Bennée b6fa2ec238 gdbstub: move chunk of softmmu functionality to own file
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.

Alex Bennée 36e067b2f2 gdbstub: make various helpers visible to the rest of the module
We will be needing to use these helpers between the user and softmmu
files so declare them in the headers, add a system prefix and remove
static from the implementations.

Alex Bennée 1678ea040e gdbstub: move fromhex/tohex routines to internals
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
now.

Alex Bennée 9f56787c12 gdbstub: move GDBState to shared internals header
We are about to split softmmu and user mode helpers into different
files. To facilitate this we will need to share access to the GDBState
between those files.

Philippe Mathieu-Daudé 55b5b8e928 gdbstub: Use vaddr type for generic insert/remove_breakpoint() API
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.

Alex Bennée ae7467b1ac gdbstub: move breakpoint logic to accel ops
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.
