Add options DDB_FROMCONSOLE and sysctl ddb.fromconsole, analagous to
...
DDB_ONPANIC. Lets user ignore breaks but enter DDB on panic. Intended
for machines where debug on panic is useful, but DDB entry is not,
(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
...
formats in DDB:
- Reverse the sense of the symbol format #ifdef... i.e. instead of
"#ifndef DB_NO_AOUT", use "#ifdef DB_AOUT_SYMBOLS". This is pulled
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.
