impl `FromMdbValue` for bool is unsound

The implementation of FromMdbValue has several unsoundness issues. First of all, it allows to reinterpret arbitrary bytes as a bool and could make undefined behavior happen with safe function. Secondly, it allows transmuting pointer without taking memory layout into consideration. The details of reproducing the bug are available here.
