Add qemu_ prefix to bitmap_set and bitmap_clear to avoid conflicts. (#1326) 
When unicorn and systemd are combined into a single binary the 2
libraries conflict on bitmap_set and bitmap_clear functions which breaks
unicorn.

Fix UAF when deleting hook while in hook callback #1127 (#1130) 
* Handle the cpu context save in a more pythonic way, so the context can be serialized and reuse in an other process using the same emulator architecture and modes

* Fix type error ; mistakes a size_t uint64_t ; breaks in 32bit...

* Fix the UAF situation when deleting a hook while being in a hook callback. Added an attribute 'to_delete' to hooks, and a list hooks_to_del to delay the free of the hooks

* Minor fixes ; forgot return type of clear_deleted_hooks ; do not declare variable in for predicate

X64 base regs (#1166) 
* x86: setup FS & GS base

* Fixed base register writes for x64, removed then for x16/x32 (the don't exist there?)

* FS reg comes before GS so the base regs do so, too

* added shebang to const_generator.py

* Added base regs to and added 'all' support to const_generator

Fix block hooks being called twice after an early exit from execution. (#1194) 
Ensure the TCG exit flag is cleared at the end of cpu_exec. This ensures
that subsequent calls are not polluted by the prior call to request an
early exit. The symptoms of the problem being addressed here are that
after a cpu_exit call triggered within a hook there may still be a
pending tcg_exit_req flag set. This then causes a block to start its
execution and then be aborted (from which point it'll continue because
there's no other condition to service). The start of the execution
causes the block hook to be called, no actual code to be run, and then
the block started again with another block hook call.

This change is discussed in ticket 1193:
