vi: failure to open file is not an error when initialising bufferCommit 32afd3a introduced these regressions on the master branch:
Starting vi with no filename on the command line gives the status message
"'(null)' Bad address" instead of "- No file 1/1 100%".
Starting vi with a non-existent file on the command line gives the status
message "'new.txt' No such file or directory" instead of "- new.txt 1/1 100%"

ntpd: relicense ntpd applet to ISC-style licenseOpenNTPd is licensed under ISC-style license so it's good idea to keep
ntpd applet under same license to avoid mess, instead of having
our changes to be under GPL.
Names of original code's authors are added.

udhcpc: account for script run timeBased on the following user report:
I ran into an issue where I was seeing a long delay in the scripts called
in udhcp_run_script. I was using an old version of OpenWrt (kamikaze)
and a satellite modem. An NTP script was being called and the modem
would sometimes take a long time to respond to the DNS lookup when
it was offline.
This delay started affecting my lease time. The lease that I wou...

libarchive: add capability to unpack to mem.bufferThe performance and number of processes for a "depmod -a" with gzipped
modules was abysmal. This patch adds a code path without fork,
benefiting all users of xmalloc_open_zipped_read_close.
"modinfo radeon.ko.gz", a single-file reader, got 30% faster.
"depmod -a", which used to fork over 800 times, got 20% faster.
Heavily based on a patch by Lauri Kasanen <curaga@operamail.com>

libbb: use sendfile() to copy data between file descriptorsBusybox already uses sendfile in httpd. This patch proposes to use it

It speeds up the copying on slow systems a lot - below are the times needed

sendfile:

libbb: use ARG_MAX for bb_arg_max() only if it's 60k+Sometimes ARG_MAX is small (like 32k) yet sysconf(_SC_ARG_MAX)

sysconf(_SC_ARG_MAX) being bigger are exponentially smaller:
you can see 4 times fewer fork+execs when you run find, but
when each execed process already takes a thousand parameters
it's likely execution time is dominated by w...
