c89493522f - Make the ddb_init() interface consistent for a.out and ELF. 
- Allow DDB to run-time switch for a.out or ELF symbol table support.

3ac3cbcfb8 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.

c291189ae9 Have to fix the `(int)curproc' lossage now; kernel builds die here on alpha. 
BTW, KNF requires the additional, not-technically-need `!= NULL'.

the current 'bootblock' method, like the Shark, which preloads and preformats
the symbol table right in the boot code.

df2b26547d If `SOFTWARE_SSTEP' is defined then kgdb_stub.c needs the single-step 
emulation in db_run.c:

	- re-arrange `db_*_single_step()' and `db_*_temp_breakpoint()' -
	  which are only used in the `SOFTWARE_SSTEP' case - so these
	  are available to the KGDB code.
	- make other code in db_run.c conditional on `DDB'.

1a8c7604f4 initial import of the new virtual memory system, UVM, into -current. 
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

9d7d537acb Clean up usage of printf() vs db_printf(): The diagnostic messages 
when symbol tables are loaded don't belong to the user interaction,
their output lines should not be counted by ddb's builtin pager.

e0ced7363a fix printf formatting of "ps" (aka "show all proc") so that lines never 
overflow (always hated that).

replaced "/m" flag with:
	/a == show process address info
	/n == show normal process info [currently the default]
	/w == show process wait/emul info

d9f8d88a35 Fixup the software single-step code (used on architectures where there 
is no hardware support for single-stepping):
- Fix branch prediction and delay slot computation (for the MIPS).
- Correctly deal with branch taken vs. branch not taken cases, and
  self-branches.
- General cleanup, including types botches.
Partially from Mach 3, with a bunch of cleanup work by me.

76fbbf772d 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.
