Andres Amaya Garcia 3d98b97442 Modify zeroize internal buffers in md modules 
Modify all the following functions to zeroize an internal buffer before
exiting the function. The buffer could potentially contain confidential
data read from a file.

* md2_file()
* md4_file()
* md5_file()
* ripemd160_file()
* sha1_file()
* sha256_file()
* sha512_file()
