Derive from prog-mode, use derived-mode-p, and fix up various

minor style issues in lisp/progmodes.

* lisp/progmodes/vhdl-mode.el (vhdl-write-file-hooks-init)
(vhdl-hs-minor-mode, vhdl-ps-print-init): Fix make-local-variable ->
make-local-hook.
* lisp/progmodes/sh-script.el (sh-require-final-newline): Remove.
(sh-set-shell): Don't set require-final-newline since it's already done
by prog-mode.
* lisp/progmodes/modula2.el (m2-mode): Don't make m2-end-comment-column
since we never set it.
* lisp/progmodes/ebrowse.el (ebrowse-set-tree-indentation):
Use read-string and standard prompt.
* lisp/progmodes/dcl-mode.el (dcl-mode-map): Move init into declaration.
* lisp/progmodes/meta-mode.el (meta-mode-abbrev-table): Merge init and decl.
(meta-common-mode-syntax-table): Rename from meta-mode-syntax-table.
(meta-common-mode-map): Rename from meta-mode-map.
Remove C-m binding, which is a user preference, not mode specific.
(meta-common-mode): New major mode; replace meta-common-initialization.
* lisp/progmodes/js.el (js-mode): Call syntax-propertize rather than messing
around with font-lock.
* lisp/progmodes/etags.el (select-tags-table-mode):
Derive from special-mode.
* lisp/progmodes/octave-mod.el (octave-mode):
* lisp/progmodes/gdb-mi.el (gdb-inferior-io-mode, gdb-threads-mode)
(gdb-memory-mode, gdb-disassembly-mode, gdb-breakpoints-mode)
(gdb-frames-mode, gdb-locals-mode, gdb-registers-mode):
Let define-derived-mode do its job.
* lisp/progmodes/cpp.el (cpp-edit-mode-map):
Move initialization into declaration.
(cpp-edit-mode): Use define-derived-mode.
(cpp-edit-load): Use derived-mode-p.
* lisp/progmodes/mixal-mode.el (mixal-mode):
* lisp/progmodes/f90.el (f90-mode):
* lisp/progmodes/cfengine.el (cfengine-mode): Don't bother setting
require-final-newline since prog-mode does it already.
* lisp/progmodes/cc-cmds.el (c-update-modeline): Use match-string.
* lisp/progmodes/asm-mode.el (asm-mode-map): Fix menu setup.
* lisp/progmodes/antlr-mode.el: Require cc-mode upfront.
(antlr-mode-syntax-table, antlr-action-syntax-table): Initialize in
the declaration.
(antlr-directory-dependencies, antlr-show-makefile-rules):
Use derived-mode-p.
(antlr-language-option): Don't assume point-min==1.
(antlr-mode): Use define-derived-mode.
* lisp/progmodes/ada-mode.el: Use derived-mode-p.
