Initial PDF shim over PS. This produces working PDF output with -Tpdf.

It's currently missing the xref table, so you'll get a warning in most
PDF viewers).  It also produces lots of redundant output, which will go
away once I get a better handle on the PDF spec.  The code doesn't
really touch any existing functionality; it's a bunch of conditionals
atop the -Tps (term_ps.c) implementation.  I'm checking it in now to
have it exist and be auditable.  It needs clean-up, polish, and general
care (and xref!).
