5ef5fd6e53 Ensure 'kvm' is always initialized. If "-M" was not specified and the
garbage value on the stack was not zero, then 'ddb capture' would try to
use the garbage value as a kvm_t pointer.

742765c971 When extracting the capture buffer from a crashdump, only read the valid
portion of the capture buffer (db_capture_bufoff vs db_capture_bufsize).
This could result in outputting garbage (e.g. lots of 'p' characters if
DIAGNOSTIC is enabled) after the end of the capture buffer.  While here,
fix a spelling nit.

0693424576 Add "ddb capture print" and "ddb capture status" commands do ddb(8),
alowing the DDB output capture buffer to be easily extracted from
user space.  Both of these commands include -M/-N arguments, allowing
them to be used with kernel crash dumps (or /dev/mem).

This makes it easier to use DDB scripting and output capture with
minidumps or full dumps rather than with text dumps, allowing DDB
output (scripted or otherwise) to be easily extracted from a crash
dump.

a1f25b0daa Add command-line tool ddb(8), which allows DDB(4) scripts to be
managed from userspace.  It is largely a wrapper for sysctl()
calls, but because the sysctls for adding and removing scripts
are awkward to use directly, this provides an easier-to-use
interface.
