Robert Xiao 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

Takacs, Philipp 073c4b74ca load_helper only call cpu_loop_exit() when emulation is running 
The load_helper is sometimes called from register writes. When the load
fails check if emulation is running before jump out of the emulated code.

Commit 640251e1aa added a size parameter to uc_hook_tcg_op_2, but this was not
reflected in the Python bindings.

reflected in sample_ctl.py.

Takacs, Philipp 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.

Takacs, Philipp 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.

Takacs, Philipp f2eb1f4711 i386 mmu hack: Allow emulate usermode without mmu 
This basicaly mappes virtual addresses to physical addresses 1:1 when
the mmu is disabled in the cpu. So you can use the full 64 bit addressspace
without required to configure the mmu.

This allows to emulate code witch fully uses the MMU. This is necesary
to allow full system emulation.
