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

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.

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 .

i386 call internal helper on special porpese register write
...
Some registers writes have side effects. i.e. write to cr3 flush the tlb,
if the PG bit is set.

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.
