[Trond Norbye (trond-norbye)]

New macros to detect sasl:

PANDORA_HAVE_SASL - detect libsasl or libsasl2. If you use this macro it will first search for libsasl, if it cannot find that it will search for libsasl2. If it finds libsasl2 it will populate the LIBSASL variables with the content of the LIBSASL2 variables so that the developer doesn't need to add double up of the logic in his code..

If you really want one of the two you can use one of the other macros:

PANDORA_HAVE_LIBSASL - detect libsasl
PANDORA_HAVE_LIBSASL2 - detect libsasl2
