sent in the rhsys handler, made it work for both redhat and debian

otherwise when you run a test run it will print: debug su $user -c "$execstr"

were necessary :)

 mysql handler: removed over-enthusiastic quote-escaping, related to su ;
 previous versions broke the mysql handler both on sarge and sid.

somewhere along the chain you will only backup the symlink, and
not the data, this is fixed here in rdiff with this change

since Makefile.in is generated through autogen.sh or autoreconf, it shouldn't be
put in the repo itself (except on release)

configure.in modified to be more selective about finding bash
configure.in modified for 0.9.3 release
autogen.sh modified to create config.guess and config.sub for release
changelog updated about autoconf changes
Removed /bin/bash TODO line
