Ensure that parsing can't be subverted by requests larger than the
default line buffer maximum size. If a line fits in the stack, great.
If not, allocate additional memory for it instead of truncating.
Add google-proftools to debug builds.
Don't clean parser.c by default, so distributions don't require ragel to
build.
Add BSD licensing.
Move helper functions out to util.c. Rename files to match function
names.
Start playing with sqlite API.
