02e6c14e12 x86: add MSR API via reg API (#755)
Writing / reading to model specific registers should be as easy as
calling a function, it's a bit stupid to write shell code and run them
just to write/read to a MSR, and even worse, you need more than just a
shellcode to read...

So, add a special register ID called UC_X86_REG_MSR, which should be
passed to uc_reg_write()/uc_reg_read() as the register ID, and then a
data structure which is uc_x86_msr (12 bytes), as the value (always), where:
	Byte	Value		Size
	0	MSR ID		4
	4       MSR val		8

47150b6df3 reg_read and reg_write now work with registers W0 through W30 in Aarch64 (#716)
* reg_read and reg_write now work with registers W0 through W30 in Aarch64 emulaton

* Added a regress test for the ARM64 reg_read and reg_write on 32-bit registers (W0-W30)
Added a new macro in uc_priv.h (WRITE_DWORD_TO_QWORD), in order to write to the lower 32 bits of a 64 bit value without overwriting the whole value when using reg_write

* Fixed WRITE_DWORD macro

reg_write would zero out the high order bits when writing to 32 bit registers

e.g. uc.reg_write(UC_X86_REG_EAX, 0) would also set register RAX to zero

428cb83060 Support for MCLASS ARM cpu (Cortex-M3) (#700)
Support for Cortex-M ARM CPU already exists in Qemu. This patch just
exposes a "cortex-m3" CPU.

"uc_open(UC_ARCH_ARM, UC_MODE_THUMB | UC_MODE_MCLASS, &uc);"
Instantiates a CPU with this feature on.

036763d6ae Fix memory leaks as reported by DrMemory and Valgrind.
ARM and probably the rest of the arches have significant memory leaks as
they have no release interface.

Additionally, DrMemory does not have 64-bit support and thus I can't
test the 64-bit version under Windows. Under Linux valgrind supports
both 32-bit and 64-bit but there are different macros and code for Linux
and Windows.

- Allow to register handler separately for invalid memory access
- Add new memory events for hooking:
   - UC_MEM_READ_INVALID, UC_MEM_WRITE_INVALID, UC_MEM_FETCH_INVALID
   - UC_HOOK_MEM_READ_PROT, UC_HOOK_MEM_WRITE_PROT, UC_HOOK_MEM_FETCH_PROT
- Rename UC_ERR_EXEC_PROT to UC_ERR_FETCH_PROT
- Change API uc_hook_add() so event type @type can be combined from hooking types
