Bug #266170: Use SOVERSION 1 for apr 1.x, because the apr 0.9.x -> 1.x
Bug #266170: Use SOVERSION 1 for apr 1.x, because the apr 0.9.x -> 1.x
ABI change leaks through the libsvn ABIs (because we use apr_off_t,
which is now 64 bits on all platforms).

Upstream refused this (http://svn.haxx.se/dev/archive-2006-03/0522.shtml
for thread), but fortunately when it came time to support apr 2.x in svn
1.7, they skipped SOVERSION 1 in consideration of Debian/Ubuntu, so we'll
be ABI-compatible again if and when we move to apr-2.x.
