Implement uc_reg_{read,write}{,_batch}2 APIs.
...
These APIs take size parameters, which can be used to properly bounds-check the
inputs and outputs for various registers. Additionally, all backends now throw
UC_ERR_ARG if the input register numbers are invalid.
Completes #1831 .

Add uc_ctl_get/set_tcg_buffer_size
...
We still need this API because the virtual memory address space of
32 bits os is only 4GB and we default need 1G per instance

Remove MMU hacks
...
Unicorn has included some ugly hacks to provide a envirement where vaddr == paddr.
These hacks where to use the full 64 bit mappings on x86 without init the mmu
and some memory redirect for MIPS.
The UC_TLB_CPU mode defaults to vaddr == paddr, therfor these hacks aren't
required anymore.

difference between stop_request and quit_request
...
quit_request is for internal use. This means the IP register was updated and
qemu needs to rebuild the translation blocks.
stop_request is set by the user (uc_emu_stop) to indecate that unicorn sould
stop emulating.
