kill: fix coding style

The kill was deprecated at the time lot of other tools got style
unification.  Now when deprecation is lifted it is time to get kill
cleaner.  This commit does not modify code, only various spacing issues,
removal of unecessary braces, and such are dealt.

kill: make usage() not to return

And change the function argument to be an output stream.  Earlier the
--help option made kill exit with none-zero value, that is now corrected.

kill: deprecat invocation as 'pid' command name

Enabling options by renaming command is both unexpected and undocumented.
This magic is now deprecated and with remark of removal of this
functionality in future.

kill: use control structure to pass user input to functions

This should make it easier to understand how the program works.

kill: tell what is wrong rather than output usage()

Getting usage as error message is not specific enough.  As a user I want
to know what is wrong, and if it is unclear after error message how to
recover then I run command with --help.

kill: add parse_arguments() function

Long main() is difficult to read, so moving argument parsing to separate
function should make sense.

kill: move sigqueue inputs to control struct

Use of global variables is messy.  The earlier implementation also
assumed queue argument never to be textual, such as 'HUP', which now
works as one might expect.

switch_root: verify initramfs by f_type, not devno

As of linux 3.14, the initramfs device will have both major and
minor 0, causing our paranoia check to fail. Make this version agnostic
by checking the filesystem type, rather than a device number.

libfdisk: make qsort_r() optional

The function is no critical for fdisk functionality. The SUN label
verification will check for less issues. All the verification code is
optional ('v' fdisk command).
