farmdve 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.

Spl3en 4c3ad139ea (Fix #341) SYSENTER instruction is not properly hooked with uc_hook_add in x86 emulation.
helper_sysenter in qemu/target-i386/seg_helper.c didn't check properly if a call interrupt callback was registred.
It has been fixed by copying the helper_syscall behavior.

farmdve 3e57615c76 Fix uc_mem_unmap memory leak and in uc_close.
It appears the problem is that we are not calling the memory region
destructor. After modifying memory_unmap to include the destructor call
for the memory region, the memory is freed.

Furthermore in uc_close we must explicitly free any blocks that were not
unmapped by the user to prevent leaks.

This should fix issue 305.

Nguyen Anh Quynh 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.

- Allow to register handler separately for invalid memory access
- Add new memory events for hooking:

   - 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

Sean Heelan 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.
