Link the subversion binaries against the Apache 2.X installed

version of APR if WITH_APACHE2_APR is defined.  This is also
implied by WITH_MOD_DAV_SVN.

I noticed some problems in testing WITH_APACHE2_APR in that
the subversion binaries would somehow be linked by the runtime
linker against APR from the devel/apr port if the latter was
installed.  Mention this potential problem at portbuild time,
although this should be handled better than it is.

PORTREVISION bump.

Based on part of the patch from the PR mentioned below.
