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

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.

Fix uc_mem_unmap memory leak and in uc_close.
...
It appears the problem is that we are not calling the memory region
destructor. After modifying memory_unmap to include the destructor call
for the memory region, the memory is freed.
Furthermore in uc_close we must explicitly free any blocks that were not
unmapped by the user to prevent leaks.
This should fix issue 305.
