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

* Remove glib from samples makefile
* changes to 16 bit segment registers needs to update segment base as well as segment selector
* change how x86 segment registers are set in 16-bit mode
* more appropriate solution to initial state of x86 segment registers in 16-bit mode
* remove commented lines
