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

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.

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.
