Octal escape sequences \NNN can have between 1 and 3 digits. If
the sequence had less than 3 digits the parser got out of sync
with an incorrect double increment of the pointer and errors out
parsing sequences like \0, \2 or \33.
Before:
Filter: ip.proto == '\33'
dftest: "'\33'" is too long to be a valid character constant.
After:
Filter: ip.proto == '\33'

Create a set_value union and move the FvalueSetByteArrayFunc pointer
into the union. Update fvalue_set_byte_array() accordingly. Check
