MFC 284913:

dconschat(8): Use NULL instead of 0 for the last argument in execl(3)

Found while experimenting with the gcc sentinel attribute.

Fix the following warning from clang trunk:

2012-03-19T19:17:55+00:00

usr.sbin/dconschat/dconschat.c:163:65: error: format specifies type 'size_t' (aka 'unsigned int') but the argument has type 'off_t' (aka 'long long') [-Werror,-Wformat]
        snprintf(buf, PAGE_SIZE, "\r\n[dconschat reset target(addr=0x%zx)...]\r\n", dc->reset);
                                                                     ~~^            ~~~~~~~~~
                                                                     %llx

Silence this by casting dc->reset to intmax_t, and using the appropriate
length modifier.  While here, wrap the line to a 80 character margin.

mdoc: drop redundant .Pp and .LP calls

2010-10-08T12:40:16+00:00

They have no effect when coming in pairs, or before .Bl/.Bd

mdoc: .Ud has attitude, it takes no argument!

- Use CTRL macro.
- Make target reset work on telnet port.
- Add a key bind to invoke kgdb on the terminal. (experimental)

Reset dc->paddr and dc->reset if we cannot read configuration ROM.
