036763d6ae 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.

9e64cba6ec 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.

90eb8f2e72 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

dfb4a9d9ad 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.
