PROT_NONE, PROT_READ, PROT_WRITE, and PROT_EXEC from mman.h.
PROT_MASK is introduced as the one true way of extracting those bits.
Remove UVM_ADV_* wrapper, using the standard names.

This allows ddb's "trace" command to include file and line numbers:
ddb{0}> trace
Debugger() at Debugger+0x9 [../../../../arch/amd64/amd64/db_interface.c:405]
ddb_sysctl() at ddb_sysctl+0x1b4 [../../../../ddb/db_usrreq.c:104]
sys___sysctl() at sys___sysctl+0x216 [../../../../kern/kern_sysctl.c:229]
syscall() at syscall+0x297 [../../../../sys/syscall_mi.h:84]

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 u_int for sizes and offsets when that happens.

- 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'.

so that the process-level stuff is to/from struct process and not
struct proc. This fixes a bunch of problem cases in rthreads.
Based on earlier work by blambert and myself, but mostly written
at c2k10.

a few arches where toolchain limitations apply) will embed some symbolic
information about the various structs used within the kernel, and have
new ddb commands allowing struct display and some useful information
gathering. Kernel rodata increase varies accross platforms from ~150KB to
~300KB.
This option is not enabled by default.

1) fix buffer cache low water mark to allow for extremely low memory machines
without dying
2) Add "show bcstats" to ddb to allow for looking at the buffer cache statistics in ddb

hit db_more(), except when it's cold and we run an automatic traceback;
aborting the traceback with `q' would then lead to undefined behaviour.

Writing to it, will bring the system into the kernel debugger.
ddb.console=1 is required and the sysctl command has to be executed
from the actual console tty.
If the securelevel is < 1, the tty check is ignored.
