Fix UAF when deleting hook while in hook callback #1127 (#1130)
* Handle the cpu context save in a more pythonic way, so the context can be serialized and reuse in an other process using the same emulator architecture and modes

* Fix type error ; mistakes a size_t uint64_t ; breaks in 32bit...

* Fix the UAF situation when deleting a hook while being in a hook callback. Added an attribute 'to_delete' to hooks, and a list hooks_to_del to delay the free of the hooks

* Minor fixes ; forgot return type of clear_deleted_hooks ; do not declare variable in for predicate

626d72d6df Two fixes to get unicorn build better with MSVC. (#1136)
* Change MSVC keywords.

typename, class, and class are all keywords for MSVC. Adding a suffix for
all of them allows a successful compilation under VC 2017 (15.9).

* Switch from /ZI to /Zi to avoid crashes at longjmp in debug builds.

1bef32fff6 Fix huge memory leak on uc_mem_protect() (#787)
A memory region is allocated inside split_region() that was only freed in error case but not on success case, leading to huge memory leak if the region size was significant.

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
