Redundant help texts (one which only repeats the description)
are deleted.
Descriptions and help texts are trimmed.
Some config options are moved, even across menus.
No config option _names_ are changed.

With the new "select PLATFORM_LINUX" mechanism
(commit e3b1a1fd28), the PLATFORM_LINUX
option alone no longer has any purpose of changing program behavior or
affecting compiled code. So there is no longer need to prompt user of
this config question.

Building & running with ASAN is super helpful, so add a dedicated config
knob for it. This way people don't have to guess at the right compiler
settings in order to get a good build. We can just tell people to enable
this one option.

Man entry for sendfile:
Not specified in POSIX.1-2001, or other standards.
Other UNIX systems implement sendfile() with different semantics and
prototypes. It should not be used in portable programs.
Select PLATFORM_LINUX if enabling FEATURE_USE_SENDFILE.

Busybox already uses sendfile in httpd. This patch proposes to use it
globally to copy data between file descriptors.
It speeds up the copying on slow systems a lot - below are the times needed
to copy a 450Mb file with and without this option enabled on a BeagleBone
Black:
sendfile:
user 0m0.000s
sys 0m8.170s
read/write 4k:
user 0m0.470s
sys 0m16.300s

This set of patches adds a simple unit-testing framework to Busybox
unit-tests: add some helper macros for unit-test framework implementation
unit-tests: implement the unit-testing framework
unit-tests: add basic documentation on writing the unit test cases
unit-tests: modify the Makefile 'test' target to run unit-tests too
unit-tests: add two example test cases
unit-tests: modify the existing strrstr test code to use the unit-test framework

Currently CONFIG_PAM depends on CONFIG_LOGIN, but is used by the httpd applet too.
This patch moves said option to general configuration, thus allowing to
compile httpd with PAM support independently from login.

We set a default path for the directory where pidfiles are create
when FEATURE_PIDFILE is selected. The default has no effect on
applets which must specify a pidfile path on the command line to
run, and it can be overridden by applets which optionally allow
the user to specify the pidfile path.
We also add pidfile write/remove support for klogd, ntpd and watchdog.
For syslogd, we add a missing remove_pidfile() for better cleanup
on daemon exit.

First, I _again_ violated it - two xz-related applets are in wrong positions.
Second, planned in-applet help text thing will be so much easier without
this requirement...
