Other fixes:
 - cppcheck filter adjustment
 - (indirect) dependency on libbotan.  actually we should be able to make
   the link within libcryptolink, so I chose that approach.  hopefully
   it doesn't break autobuild.

they were actually not "SOURCES", and caused distcheck failures.
discussed on jabber.

use -L`botan-config --prefix`/lib and -I`botan-config --prefix`/include.

if nothing (or --with-botan) is specified it will be taken from $PATH, if --with-botan=dir is specified it will be taken from $withval/bin
If --without-botan is specified configure will print an error

(also made a minor editorial cleanup: removed a redundant space in .cc)

consists of the originally proposed patch with additional fixes to bin/stats
to make it testable

Also updated includes (because of the lib/util move)

added new test for that.
with some other cleanups.

noticed in previous review, but forgot to mention that.
very trivial, so decided to push it directly.

convert TSIG name to the generic crypto hash algorithm enum.

in the canonical form (i.e. downcased).

(with some non related cleanups)
