Windows vulnerability fix : finally make bootloader decompressor more robust and secure by adding multiple checks and validation code. This solves the issue found by the Open Crypt Audit project. Note that we had to switch to the slow implementation of the function decode in order to keep the size of the decompressor code under 2K.
