Valgrind fixes.

* src/devices/grohtml/html-table.cc (html_table::~html_table):
Deallocate `columns' list.
* src/devices/grohtml/post-html.cc (char_block::~char_block):
New destructor.
(text_glob::text_glob_html, text_glob::text_glob_special,
text_glob::text_glob_line, text_glob::text_glob_auto_image,
text_glob::text_glob_tag): Avoid memory leaks.
(text_glob::remember_table): Free memory before reassigning.

Add glyph `+e', greek lunate epsilon symbol, and `-h' (with the
alias `hbar'), the Planck constant over two pi.

* font/devdvi/generate/texmi.map: Use `*e' for position 15 and
`+e' for position 34.
* font/devdvi/generate/texsy.map: Replace `DI' and `HE' with
`u2662' and `u2661'.
* font/devdvi/{MI,S}: Regenerated.
* font/devhtml/R.proto, font/devutf8/R.proto: Add `+e', `-h', `hbar'.
* font/devlbp/*: Add `hbar' alias.
* font/devlj4/generate/special.map: Ditto.
* font/devlj4/S: Regenerated.
* font/devps/generate/symbolchars: Add `+e'.
* font/devps/generate/textmap: Fix PS name for `-h'.
Add `hbar' alias.
* font/devps/symbolmap: Regenerated.

* src/devices/grops/ps.cc (transform_fill): Removed since unused.

* src/roff/troff/glyphuni.cc (glyph_to_unicode_list): Add `+e',
`-h', `hbar'.
* src/roff/troff/uniglyph.cc (unicode_to_glyph_list): Add `+e',
`-h'.

* tmac/X.tmac, tmac/ps.tmac: Provide definitions for `-h' and
`hbar'.
* tmac/tty-char.tmac: Add `+e'.
