The applets with "<applet> [opts] PROG ARGS" API very quickly exec
another program, noexec is okay for them:
chpst/envdir/envuidgid/softlimit/setuidgid
chroot
chrt
ionice
nice
nohup
setarch/linux32/linux64
taskset
cttyhack
"reset" and "sulogin" applets don't have this form, but also exec
another program at once, thus made noexec too.

busybox's chpst first switches user/group and then tries to call nice().
Once the root priviledges are dropped, process priority can only be lowered.
So negative nice values don't work anymore.
Upstream version of chpst correctly calls nice() before switching user.

When using svlogd's processor functionality to run arbitrary commands
on log rotation, the line in the config is executed verbatim, i.e. the
exclamation mark is included.
For example, if the config file contains:
s100
!cat
then when it's time to rotate the log files after each 100 bytes, sh -c
"!cat" will be run, instead of sh -c "cat" as intended. The result is
svlogd logging
/bin/bash: !cat: command not found
svlogd: warning: processor failed, restart: /tmp/svlogd/
over and over again as it keeps attempting to execute the processor and
failing (unless you happen to have a "!cat" binary around :)).
Skipping the exclamation mark when performing the wstrdup() fixes the
issue.

We use functions from sys/resource.h in misc applets, but don't include
the header. This breaks building with newer glibc versions, so add the
include where needed.

This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).
