[gpsd-dev] cfmakeraw part 2

[Greg Troxel]

An explanation of the cfmakeraw issue is at:

  https://perkin.org.uk/posts/solaris-portability-cfmakeraw.html

The short story is that cfmakeraw is a nonportable extension, but
apparently the same everywhere it exists, which I think includes linux,
*bsd, mac.

Perhaps gpsd.h should add __sun to the cfmakeraw decl, making the
implementation in serial.c visible, and not patch gpspipe.c.  I am
inclined to just do this and let the solaris people deal on the slight
chance that's wrong.

Is that ok?
