PAGE_SIZE boundaries. This is required to enforce proper separation of
sections when adding page protections (coming shortly).
This was in snaps before release with no reported side effects.

We run the DWARF line table program to generate each row of the table
until we find a row after the one we wanted, and then take the
previous row's entries. The code correctly took the previous row's
line number entry, but incorrectly took the current row's file name
entry. Notably, this caused DDB to report the wrong file names for
inlined calls to functions defined in header files.

delete coredump_trad(), uvm_coredump(), cpu_coredump(), struct md_coredump,
and various #includes that are superfluous.
This leaves compat_linux processes without a coredump callback. If that
ability is desired, someone should update it to use coredump_elf32() and
verify the results...

the end of the kernel area to 2MB, so that the direct map pages can then
have the W permission removed (X permission was already removed in a previous
diff). This creates a VA hole at the end of bss, so adjust for that since
that's where symbols get loaded by the bootloader (for now, map that region
RO until the boot loader can be updated to place the symbols at "end" instead
of "end of bss").

This allows ddb's "trace" command to include file and line numbers:

For this to work, it requires using a new version of boot(8), and
booting a kernel with the .debug_line section present (e.g., building
with ``makeoptions DEBUG="-g"'' and then booting the bsd.gdb kernel
instead of the stripped bsd kernel).
Still a WIP, but no failure reports yet. Committing so further
development and testing can happen in tree.

Now, for kernel to "reboot" (reboot, halt, or shutdown), MD boot(9) is called
in some places. This change introduces a new MI function reboot(9) which is
simply a wrapper to call MD boot(9).

Includes a stand-alone addr2line clone for userspace testing.
Tested extensively on amd64 and expected to eventually support other
architectures too. Importing now so further development/testing can
happen in-tree. Followup commits will add to the kernel build and
integrate into ddb.

- switch to perl for better data structures and (thus) speed
- fix a couple glitches in the interpretation of the stabs output
- compress the strings by putting them in one big array and overlaying
suffixes
- all sizes and offsets are <64k, so use u_short for them
This results in ~60% reduction in the resulting text size and it now
takes less than a second to create on fast platforms.

message "value is not available" was misleading. Use the ENODEV
error to generate the more appropriate message "Operation not
supported by device". Note that ddb.console must be set to 1 to
see that error at all.

not advance the address until the last modifier has been processed. This
allows sequences like `x/xi address,count' to yield meaningful results.
As a bonus, handle `i' and `I' modifiers last, so that I don't have to
fight my habit of using `x/ix' instead of `x/xi'.
