* tests/test-ls.c: new test program reading and displaying the iPod

content
* tests/test-rebuild-db.cc: new test program which looks for mp3 files
on the iPod in the Music dir and rebuild an iPod database from that
(it uses taglib to parse the tags, so it's conditionnally built
depending on taglib's availability)
* configure.ac:
* tests/Makefile.am: build system changes to accomodate the 2 new test
programs
