security/suricata: Update to 2.0.3, Modernize

Now that libprelude is safe from EXPIRE and has been staged [1], and devel/libhtp
now *actually* links against libiconv even though autoconf detection was fine
[2] ... Have fun!

- Update to 2.0.3
- Switch libhtp to the upstream version port (devel/libhtp)
- Use USES=libtool
- Use OPTIONS helpers and other OPTIONS_* goodies
- Sort USE(S)* section
- Deprecate USE_AUTOTOOLS (USES instead)
- Deprecate AUTOMAKE_ARGS, ACLOCAL_ARGS (no longer necessary)
- Update COMMENT
- Add m4 macro for checking compiler flags and add relevent
  check to configure.ac. Our GCC doesn't like
  -Wno-error=unused-result and upstreams configure bits arent as
  portable as they could be.
