Revert introduction of db_alloc.h.

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.

g/c now unneded stuff, like db_machine_commands_install(), db_machine_init()

Patch written by enami.

constify a little

add ddb commands "show uvmexp" and "show ncache".
the former used to be "call uvm_dump", the latter is new.

Rename the machine-specific stack trace printing functions
from db_stack_trace_cmd() to db_stack_trace_print(),
and add an additional argument, a function pointer for an
output routine (i.e. printf() or db_printf()).

Add db_stack_trace_cmd() in db_command.[ch], calling
db_stack_trace_print() with db_printf() as the printer.

Move count==-1 special handling from db_stack_trace_print() [nee
db_stack_trace_cmd()] to db_stack_trace_cmd() [nascent here].

Again, I'm unable to test compilation on all affected platforms,
so advance apologies for potential brokenness.

Add a "sifting" command to ddb (named from the Sun OpenPROM command of
the same name); it searches the symbol table(s) for all symbols matching
a given substring, and prints.

Extremely useful for when you forget that critical symbol name.

Also, with /F support (cf. "ls -F") to print a char indicating the
symbol type.

add ddb commands for printing vnodes and bufs.

- 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
