This changes (again...) our system md5 detection to cope with how OpenIndiana does md5. I'm becoming increasingly convinced this isn't worth our while (we should have just done samba_md5...), but for now this change seems to work on FreeBSD, OpenIndiana and Linux with libbsd. This needs us to rename struct MD5Context -> MD5_CTX, but we provide a config.h define to rename the type bad if MD5_CTX does not exist (it does however exist in the md5.h from libbsd).
