Add to the fundamental types passed between the scanner and the parser.
Besides "STRING", there is now "UNPARSED_STRING", where the distinction
is that "STRING" was a double-quoted string and "UNPARSED_STRING" is just
a sequence of characters that the scanner didn't know how to scan/parse,
so it's up to the Ftype to parse it.
This gives us more flexibility and prepares the dfilter parsing engine
for the upcoming addition of the "contains" operator.
In the process of doing this, I also re-did the double-quoted string
support in the scanner, so that instead of the naively-simple support we
used to have, double-quoted strings now can have embedded dobule-quotes,
embedded octal sequences, and embedded hexadecimal sequences:
"\"" embedded double-quote
"\110" embedded octal
"\x48" embedded hex
Enhance the dfilter unit test script to be able to run a single collection
of tests instead of having to run all of them all the time.
