ad7ae63e92 Remove unmapped/freed memory regions from the object property list. 
This commit fixes the following issues:
- Any unmapped/free'd memory regions (MemoryRegion instances) are not
  removed from the object property linked list of its owner (which is
  always qdev_get_machine(uc)). This issue makes adding new memory
  mapping by calling mem_map() or mem_map_ptr() slower as more and more
  memory pages are mapped and unmapped - yes, even if those memory pages
  are unmapped, they still impact the speed of future memory page
  mappings due to this issue.
- FlatView is not reconstructed after a memory region is freed during
  unmapping, which leads to a use-after-free the next time a new memory
  region is mapped in address_space_update_topology().

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.

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.

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.

 - UC_HOOK_MEM_WRITE_ERR -> UC_HOOK_MEM_WRITE_INVALID
 - UC_HOOK_MEM_FETCH_ERR -> UC_HOOK_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

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.
