Let configure automatically infer path to installed Dovecot and don't rely on installed libtool .la files anymore (patch by Timo Sirainen).

Made deprecated notify extension implementation compatible with cmusieve, except for the denotify command.

Fixed bug in configure script that emitted Dovecot version in config header in stead of Sieve version.

Enabled (optional) support for Valgrind in the testsuite and fixed a few intricate bugs in the process.

Removed code duplication between testsuite and commandline tools. Also restructured source code of the tools.

Merged mail-raw implementations of sieve commandline tools and the testsuite, thus removing duplicate code.
