ffeddd7579 use qemu_memalign for all cpu structs
Some structs, specically CPUARMState is 16-bytes aligned.

This causes segment fault because gcc tends to vectorize

the assignment of the struct with infamous movaps tricks.

Without this patch, we fail on manylinux with 2.17 glibc

in release mode in i686.

qemu_memalign will ensure the alignment across platforms.

30d202b89e Simplify reg_read/reg_write, obtaining a perf boost.
Single reg_read/reg_write is now about 25% faster.

074566cf69 Slight refactoring to reduce code duplication.
This also comes with a performance bump due to inlining of reg_read/reg_write
(as they're only called once now) and the unlikely() on CHECK_REG_TYPE.

4055a5ab10 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.

e96ac42b2e 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.

b7b1a4d6b4 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.
