Regarding issue with auxprop plugin

Hello,
sasl installs the plugins in $prefix/lib/sasl2, which defaults to /usr/
local/lib/sasl2, but looks for them in $plugindir, which defaults to
/usr/lib/sasl2 . So "./configure && make install" does not work.
To check if this is related to you, find the directory containing the
plugins are installed, e.g. /usr/local/lib/sasl2 and the
directory checked by pluginviewer, e.g. by running it behind strace.
It could be something completely different, however, I don't recall the
details now.
This patch:
- ensures a usable system after "./configure && make install", in
particular
it abolishes the possibility to install plugins in one directory
and load
them from another;
- installs the plugins by default in $(libdir)/sasl2;
- looks for configuration files by default in the directory, where
plugins are
installed, as de jure it has always been, and in
${sysconfdir}/sasl2 instead
of /etc/sasl2;
- updates ./configure --help accordingly;
