Fix (pdfwrite) : Compress charproc streams.
DETAILS:
This patch mixes 3 changes :
1. Applying a compression to vector charprocs. Bitmap charprocs are
left uncompresed. The written PDF should have same contents as before.
2. A preparation to Type 1 pattern accumulation with implementing
a pdf_substream_save stack. Moved accum_char_proc_* fields to there.
This change should be equivalent.
3. Renamed cos_write_stream_from_pipeline to cos_stream_from_pipeline,
because the old name appears confusable.
A new function with the old name is defined for another purpose.
No regression changes expected.
