pdfwrite - regenerate gs_c_pdf_glyph_type array after Encoding changes

Commit 4d91c6ad3e76e19f36d23a50dce253fbbc7d0560 manually altered the
'known encoding' to add a number of missing strings. However this did
not update an array which pdfwrite depends upon leading to incorrect
ToUnicode entries being emitted.

This commit regenerates the files gscedata.c, gscedata.h, gdevpdtv.c
and gdevpdtv.h using the program toolbin/encs2c.ps which is the correct
method for updating these files (from the stored encodings).

In addition commit 87eed438b0cffba111371c25e1d169163f310465 updated
the encs2c.ps program by adding some information to the comments
regarding using the program, specifically to include gs_css_e.ps.

This commit also updates the program still further to emit the current
boilerplate for the copyright comments, stop writing the old CVS ID
and adds a sterner warning to the comments in the .c and .h files about
using the program to regenerate these files rather than manually
modifying them.
