Include guards for libraries should use a prefix that is meaningful for
the library to avoid conflicts with other user code. For Suricata, use
SURICATA.
Additionally, remove the pattern of leading and trailing underscores as
these are reserved for the language implementation per the C and C++
standards.

This commit allows the byte_test keyword to accept an existing
variable name for a value (the value may still be specified directly as
an integer).
All nbytes values are subject to the same value constraints as before
- 23 if included with string
- 8 otherwise
The Match functions don't need a pointer to the SigMatch object, just the
context pointer contained inside, so pass the Context to the Match function
rather than the SigMatch object. This allows for further optimization.
Change SigMatch->ctx to have type SigMatchCtx* rather than void* for better
type checking. This requires adding type casts when using or assigning it.
The SigMatch contex should not be changed by the Match() funciton, so pass it
as a const SigMatchCtx*.
