fixes #19

this is needed to make sure it always compiles with PIC

amalgamated build concatenates all files into a single .c file to
allow compiler see all symbols and produce possibly smaller code.
for binary distributions this is what you want, as it's faster but
may consume more memory during compilation.
it however cannot do incremental builds.

also some cleanup and version bump to Q2

this hooks into query resolution and collects counters on answers, queries and iterator
