Issue #364 - Move RIP/PC closer next to the offending self-modifying code

which modified the 2nd next instruction (imul) in which that escaped
our wonderful ability to invalidate the
instruction translation cache in which we badly need to pick up the
self-modification being made.

When attempting to set all flags except trap flag, the EFLAGS value
should be 0x00244ED7, I've tested this on Windows and here
https://ideone.com/WQAvk1 which is presumably Linux.
Unicorn however has the value 0x00000ED7, bits 11-21 are not set. Bit 21
is the ID bit indicating whether or not CPUID is available.

X86 zero-byte opcode causes Unicorn to crash.
...
The opcode 0x00 translates as `add byte ptr ds:[eax],al`, which leads to
a segfault in Unicorn.
Using a debugger, I believe the crash is located in
`qemu/translate-all.c` in function `page_flush_tb_1`, more specifically
this code `pd[i].first_tb = NULL;`

Rename some hook related enums:
...
- UC_ERR_READ_INVALID -> UC_ERR_READ_UNMAPPED
- UC_ERR_WRITE_INVALID -> UC_ERR_WRITE_UNMAPPED
- UC_ERR_FETCH_INVALID -> UC_ERR_FETCH_UNMAPPED
- UC_MEM_READ_INVALID -> UC_MEM_READ_UNMAPPED
- UC_MEM_WRITE_INVALID -> UC_MEM_WRITE_UNMAPPED
- UC_MEM_FETCH_INVALID -> UC_MEM_FETCH_UNMAPPED
- UC_HOOK_MEM_READ_INVALID -> UC_HOOK_MEM_READ_UNMAPPED
- UC_HOOK_MEM_WRITE_INVALID -> UC_HOOK_MEM_WRITE_UNMAPPED
- UC_HOOK_MEM_FETCH_INVALID -> UC_HOOK_MEM_FETCH_UNMAPPED
- UC_HOOK_MEM_INVALID -> UC_HOOK_MEM_UNMAPPED
This also renames some newly added macros to use _INVALID postfix:
- UC_HOOK_MEM_READ_ERR -> UC_HOOK_MEM_READ_INVALID
- UC_HOOK_MEM_WRITE_ERR -> UC_HOOK_MEM_WRITE_INVALID
- UC_HOOK_MEM_FETCH_ERR -> UC_HOOK_MEM_FETCH_INVALID
- UC_HOOK_MEM_ERR -> UC_HOOK_MEM_INVALID
Fixed all the bindings Java, Go & Python.

This commit continues the PR #111
...
- 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
