grammar: Speed-up quoted string parsing
On the sysmoBTS (ARM7TDMI) the parsing of a simple response
with quoted string takes up to 200ms. Parsing the single
digest line takes 40ms itself. Create a custom parser to
speed things up to avoid the backtracking between three
optional parsers that are combined in a choice.
