New syntax for mt print symbols,msymbols,psymbols.

gdb/ChangeLog:

	* NEWS: Document new syntax for "mt print symbols", "mt print psymbols"
	and "mt print msymbols" commands.
	* psymtab.c (DEV_TTY): Delete.
	(dump_psymtab_addrmap): Don't dump if psymtabs_addrmap is NULL.
	(maintenance_print_psymbols): Rewrite for new syntax:
	mt print psymbols [-objfile objfile] [-pc address] [outfile]
	mt print psymbols [-objfile objfile] [-source source] [outfile]
	(_initialize_psymtab): Update help text.
	* symmisc.c (maintenance_print_symbols): Rewrite for new syntax:
	mt print symbols [-pc address] [outfile]
	mt print symbols [-objfile objfile] [-source source] [outfile]
	(maintenance_print_msymbols): Rewrite for new syntax:
	mt print msymbols [-objfile objfile] [outfile]
	Only print symbols for the current progspace.
	(_initialize_symmisc): Update help text.

gdb/doc/ChangeLog:

	* gdb.texinfo (Symbols): Update docs for symbol printing maintenance
	commands.

gdb/testsuite/ChangeLog:

	* gdb.base/maint.exp: Update tests for maint print symbols, psymbols
	and msymbols.

+If @code{-objfile @var{objfile}} is specified, only dump symbols for
+that objfile.
+If @code{-pc @var{address}} is specified, only dump symbols for the file

+@code{main}.

+These commands are used to debug the @value{GDBN} symbol-reading code.
+These commands do not modify internal @value{GDBN} state, therefore
+@samp{maint print symbols} will only print symbols for already expanded symbol
+tables.
+You can use the command @code{info sources} to find out which files these are.
+If you use @samp{maint print psymbols} instead, the dump shows information
+about symbols that @value{GDBN} only knows partially---that is, symbols
+defined in files that @value{GDBN} has skimmed, but not yet read completely.
+Finally, @samp{maint print msymbols} just dumps ``minimal symbols'', e.g.,
+``ELF symbols''.
