Fix MD5 detection in the autoconf build

Browse Source 
This is a front port of patches made in 3.6.x branch for bugs:
* 9037
* 9086
* 9094
* 9418

It checks if there is a library for md5 related functions (libmd or
libmd5) and if so it checks for the presence of md5.h headers it also
respect the need for osX build to not use samba's md5 implementation as
it's already present in the system libs.
