[RFA]: Remove unused header files.

[jtc@redback.com (J.T. Conklin)]

The enclosed patch removes some more unused header files from *.c
files.  Unlike the last time, this list was generated from a lint
program that ensures that no macro, typedef, struct, union, enum, or
declaration was used from the header.  This was run on one config, so
there are many files that haven't been processed yet.  First things
first.

In several instances it identified two header files, <errno.h> and
<linespec.h>, as unnecessary because <errno.h> is unconditionally
included in defs.h; and the only declaration in linespec.h
(decode_line_1) is also defined in symtab.h.

I'm unsure about the correct way to handle those are.  As long as
errno.h is included in defs.h, I see no reason to include it in any
*.c file.  One could argue that errno.h should be remove from defs.h,
but since errno (or the E* macros) is used in almost every file, I 
suspect we'd have to #include it in many files.

The decode_line_1() declaration (IMO) indicates a unclear separation
of interface and implementation.  (Again, IMO) a function declaration
should only be in one header.  Please share your thoughts, on this 
specific case, and in general.  decode_line_1() is the first of many
functions that have multiple declarations.
