Log Message:

Added three new requests `schar', `fschar', and `rfschar'.  `schar'
defines a glyph which is searched after the check for fonts declared
with `.special' (and before the check for all mounted special
fonts).  `fschar' defines a glyph for a particular font which is
searched after the check for fonts declared with `.fspecial' (and
before the check for fonts declared with `.special').  `rfschar'
removes glyphs defined with `fschar'.

* src/roff/troff/token.h (char_mode): New enum.
Declare do_define_character.
* src/roff/troff/charinfo.h (charinfo): Replace `fallback' with
`mode'.
