d9d2c4e581 fix uc_mem write with cow when using upper half of the address 
uc->target_page_align is a uint32_t. When the binary not will only
invert the 32 bit of the value. Used this in a binary and operator with
a uint64_t will case the upper 32bit of the address to be 0. Therefor
the bug only appears when the upper 32bit of the address are used.

Now a local uint64_t variable is used for the alignemend and the test
uses a not page alligned address which does not fit in 32bit.

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.

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

8b2c477578 clear the TLB cache in uc_ctl_flush_tlb 
uc_ctl_flush_tlb implies that the tlb is flushed. This change adds
UC_CTL_TLB_FLUSH which clears the TLB and set the uc_ctl_flush_tlb
alias to UC_CTL_TLB_FLUSH. Also adds a uc_ctl_flush_tb alias for
UC_CTL_TB_FLUSH.

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.

The MemoryRegion already contains a pointer to the RAMBlock. So it is
not necesary to search for it.
