202d9a6464 Config: select PLATFORM_LINUX if using sendfile() 
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.

8d75d794ea libbb: use sendfile() to copy data between file descriptors 
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

265a74b983 Kbuild: move CONFIG_PAM to general configuration 
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.

12677acf0a CONFIG_PID_FILE_PATH: new configuration option for pidfile paths 
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.
