9f94191a64 Remove double-free 
This was previously released at uc_close ../uc.c:286

    if (uc->release)
        uc->release(uc->tcg_ctx);

Which effectively does:

    object_unref(uc, OBJECT(uc->root));

1087ba9dea [query] add UC_QUERY_PAGE_SIZE uc_query helper 
Return the current page size used by the current arch.
Useful to call uc_mem_map() with memory/size aligned.

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.

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.
