ddb: New `show all tstiles' command.

Shows who's waiting for which locks and what the owner is up to.

XXX pullup-10

Add DDB_DUMPSTACK to opt_ddbparam.h.
PR kern/56445

One option per-line for opt_ddbparam.h options. Sort.

defparam DB_MAX_WIDTH

branches: 1.12.16;
Add command to print device list.

- add ddb.panicstackframes to avoid scrolling the interesting parts of panic
stacktraces off.
- change valuep to void * to avoid casts
- sort and use c99 initializers in variables array

Define ddb module.

Hook the new ddb/db_panic.c to the build.

branches: 1.8.2;
Make DB_MAX_LINES a kernel option

branches: 1.7.2;
Define SYMTAB_SPACE in opt_ksyms.h, not opt_ddbparam.h. Ensure
that ddb(4) code is independent of SYMTAB_SPACE value.

obsolete DB_AOUT_SYMBOLS. however, we need to leave most of the code
in db_sym.[ch] as it is used by the elf version of crash(8).

i will be cleaning up the db_sym.c code in a follow up commit to avoid
having dead code compiled.

branches: 1.5.4; 1.5.6;
kgdb still needs db_{get,put}_value in ddb/db_access.c when SOFTWARE_SSTEP is defined in db_machdep.h.

KGDB does no longer refers to ddb/db_access. Fixes compilation problems of KGDB
kernels.

Make ddb compile and work in userspace. Mostly this is comprised of three
types of changes:

- Add a few new methods to replace stuff like p_find(), CPU_INFO_FOREACH.

- Use db_read_bytes() instead of accessing kernel structures directly,
and similar changes.

- Add ifdef _KERNEL where the above hasn't been done, and an XXX comment.

branches: 1.2.24; 1.2.32; 1.2.38;
Add a new option DDB_VERBOSE_HELP that adds online help to ddb.
From Adam Hamsik.
Minor modifications by me, all bugs are probably mine.

branches: 1.1.2; 1.1.4; 1.1.22; 1.1.36; 1.1.50; 1.1.52;
Move DDB files to files.ddb
XXX couple of kgdb references -- clean up later
