Mmm.. alignment issues.

If you're thinking the auth calculation fails, start by adding some 
ast_log() here and there.

My suggestion would be to put some in utils.c first, in ast_md5_hash() 
(*). Print input and output and compare it to md5sum(1). If the md5 util 
is absolved, add some in the chan_sip auth handling and try to pinpoint 
why the results are off.

datatype in MD5Update.)
