> Allow empty blob literals in CQL3

> The current grammar don't allow empty blob literals (so '0x'). The goal here
> is to allow the following syntax for that:
> {noformat}
> INSERT INTO test(k, b) VALUES (0, 0x)
> {noformat}
> I'll admit that '0x' is not the most beautiful syntax ever, but I think
> that's the only thing that make sense.
> I'll note that currently there is 2 workaround to insert empty blobs: you can
> either use prepared statement (not a bad idea when using blobs anyway) or,
> because we've deprecated but still support until 2.0 using strings as blob
> (to allow upgrade from 1.2.0 to 1.2.1), you can use an empty string. I'll
> note that this latter workaround will trigger a deprecation warning in the
> log however and will stop working in 2.0.
