- change db_cmd_list() to list commands vertically rather than horizontally
...
- sort entries in the various command tables, so that the `help' lists
are easier to use. this included hacking db_machine_commands_install()
to search for the "machine" entry to change the `more cmds' pointer,
rather than assuming it was the first entry
- add a `sync' command, which is effectively `reboot 0x100'.
- remove db_help_cmd(); it was unused (and was almost a duplicate of
db_cmd_list()).
- move some extern decls to db_output.h, since they're used in more than one
place now
- rename NEXT_TAB to DB_NEXT_TAB and move to db_output.h

Add options DDB_FROMCONSOLE and sysctl ddb.fromconsole, analagous to

(public-access console, or terminal-servers which send spurious breaks)
Add new ddb hook, console_debugger(), which decides whether or not to
ignore console ddb requests. Console drivers should be updated to call
console_debugger(), not Debugger(), in response to serial-console
break or ddb keyboard sequence.

A few small changes to make it easier to support non-a.out symbol table

- Reverse the sense of the symbol format #ifdef... i.e. instead of

in from <machine/db_machdep.h>.
- Change the signature of X_db_sym_init(). Instead of int * and char *,
it now takes void *'s for the start and end of the symbol table.
- In X_db_sym_init(), check that the pointer to the beginning of
the symbol table is aligned.
- X_db_symbol_values() now takes a "db_symtab_t *symtab" argument.
