Check for TLB invalidation after read callback(s). ( #1122 )
...
* Adding regression test for issue where writing memory into a read only segment during a access callback fails.
* Check for TLB invalidation when calling read callbacks; Writes to read-only memory by the callback cause a TLB flush which requires a re-read of the TLB.

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

Revert "Remove uc_cb_eventmem_t as it is identical to uc_cb_hookmem_t"
...
As pointed out by aquynh the return types are actually different. A
uc_cb_eventmem_t callback returns a bool, while uc_cb_hookmem_t has a
void return type.
This reverts commit cb2b97f26c
