Improve documentation of pdumper; minor code cleanup
* src/emacs.c (usage_message): Add the --dump-file option. (string_starts_with_p, find_argument): Functions removed; use 'argmatch' instead. (PDUMP_FILE_ARG): Macro removed; use literal strings instead, as with other command-line options. Use HAVE_PDUMPER for cpp conditionals which used PDUMP_FILE_ARG. (load_pdump, main): Use 'argmatch' for "--dump-file" and "--temacs" arguments, thus supporting the "-dump-file" and "-temacs" variants, for consistency with other options. (main): Remove the extra fatal error for using --dump-file in unexec'ed Emacs: load_pdump does that anyway. (standard_args): Add --dump-file and --temacs, with appropriate priorities. * etc/NEWS: Expand on the pdumper support. * doc/emacs/cmdargs.texi (Initial Options): Document the '--dump-file' command-line option.
