Summary: Patch for more structured font writing

Initial Comment:
Now there are individual structures for font
dictionaries and font descriptors. Several font objects
can share the same descriptor structure. All structures
are registered in AVL trees and flushed at the end. The
fm_entry structure is cleaned up, now contains mostly
map related stuff. Font descriptors can be shared also
by embedded PDF files. tfm_of_fm() is gone. New
makesubsettag() based on md5sum() with collision
detection. Written encoding vectors are minimized in
size (try it out on pdftex-t.tex :-) Replacement of
Type1 fonts from embedded files seems to work.

TrueType writing not yet done, currently broken. Help
appreciated!

More see readme.pdf included in patch .tar file.

Regards, Hartmut
