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.

on some hook events, uc_hook_add() should not allow more than 1 handler. this add UC_ERR_HOOK_EXIST error type

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
.
