Revision 403330

MFH: r402228 r403193

I did not originally intend to backport r402228, but the LibRaw CVE fixes
only apply on top of 0.17 releases (the API and the code in 0.16.x is too
different).

r402228:
  - Update  graphics/libraw to 0.17.0
  - While here, minor port cleanup, switch to options helpers
  - Bump PORTREVISIONs of consumers as soversion has changed
