Various Win32 API additions/fixes (#616)

Various Win32 API additions/fixes

* add a get_size method to Miasm heap object, which allows the
implementation of mscvrt_realloc
* add the concept of "current directory", with the default value being
arbitrary set to "c:\tmp", which allows the implementation of
{Get,Set}CurrentDirecrtory
* various other methods implemented:

 - advapi32_RegCloseKey
 - advapi32_RegCreateKeyW
 - advapi32_RegSetValueExA
 - advapi32_RegSetValueExW
 - kernel32_GetProcessHeap
 - msvcrt_delete
 - msvcrt_fprintf
 - msvcrt_fwrite
 - msvcrt__mbscpy
 - msvcrt_new
 - msvcrt_realloc
 - msvcrt_sprintf
 - msvcrt_srand
 - msvcrt_strrchr
 - msvcrt_swprintf
 - msvcrt_wcscat
 - msvcrt_wcscmp
 - msvcrt_wcscpy
 - msvcrt__wcsicmp
 - msvcrt_wcslen
 - msvcrt_wcsncpy
 - msvcrt__wcsnicmp
 - msvcrt_wcsrchr
