Gsoc weekly status #2:capsicumizing base system

Hello,
Previous week,I uploaded my modification of wall(1) to the phabricator. The
code can be found
in (https://reviews.freebsd.org/D45567),last week I only test it in
straight forward use case,so it needs more testing on
nonblocking behavior.This week I will start capsicumizing tftpd and do more
modification on wall, fix the problem of it,and come up with how to test
wall() in nonblocking status.
complete work:
uploaded wall(1)
next work:
start capsicumizing tftpd(8)
Test wall(1)

Regards
Hans Lu
