I have gotten the B'1001'-style syntax to work, but the zpbit_in function
rejects the input. You need to change the *_in functions to accept input
in the form of a string of only 1's and 0's. Also, the output functions
should print 1's and 0's.
I'm somewhat confused about the <hex string>s; according to the standard
they might also be a BLOB literal. I'd say we get the binary version
working first, and then wonder about this.

The parser converted 'position(a in b)' into 'strpos(b, a)'. I changed it
so it converts it into 'position(b, a)' and aliased the other functions
appropriately. I changed the order of your arguments for that.

Similar issue as above. Should work now.
