012db8222e pidof: Fix separator option
Short separator option used 's' instead of 'S' which
meant it pidof would use the single-shot option when you
meant separator.

Added alias for -S using -d to give some sysvinit pidof
compatibility.

fb44ecf12f docs: Note limitation of pidof find scripts (catch up)
--------------- Original Master Branch Commit Message:
pidof will miss scripts that are run a certain way due to how
they appear in procfs. This is just a note to say it might miss
them.

7f5971058a pidof: allow to change a separator put between pids
I frequency use pidof command with strace system call tracer.
strace can trace MULTIPLE processes specified with "-p $PID"
arguments like:

	  strace -p 1 -p 1030 -p 3043

Sometimes I want to do as following

	  strace -p $(pidof httpd)

However, above command line doesn't work because -p option
is needed for specifying a pid. pidof uses a whitespace as
a separator. For passing the output to strace, the separator
should be replaced with ' -p '.

This maybe not a special to my use case.

This commit introduces -S option that allows a user to specify a
separator the one wants.

    $ ./pidof bash
    ./pidof bash
    24624 18790 12786 11898 11546 10766 7654 5095
    $ ./pidof -S ',' bash
    ./pidof -S ',' bash
    24624,18790,12786,11898,11546,10766,7654,5095
    $ ./pidof -S '-p ' bash
    ./pidof -S '-p ' bash
    24624-p 18790-p 12786-p 11898-p 11546-p 10766-p 7654-p 5095
    $ ./pidof -S ' -p ' bash
    ./pidof -S ' -p ' bash
    24624 -p 18790 -p 12786 -p 11898 -p 11546 -p 10766 -p 7654 -p 5095
    $ strace -p $(./pidof -S ' -p ' bash)
    strace -p $(./pidof -S ' -p ' bash)
    strace: Process 24624 attached
    strace: Process 18790 attached
    strace: Process 12786 attached

f5d15f4718 pidof: support for omitted %PPID and additional separators
This commit introduces support for special %PPID value that
can be passed to the -o option as a substitution for parent
PID. It also allows users to use two additional separators
for omitted PIDs - colon and semicolon.

afe862ebe4 pidof: reimplemented from scratch (replacing sysvinit pidof)
As the sysvinit becomes obsolete, some of the bundled tools
need to find a new home. The procps-ng project seems to be
the most suitable project for adopting the pidof tool.
This commit introduces a redesigned version of pidof
that satisfies the LSB requirements.
In corner cases the behaviour might differ from the former
one as the new version doesn't use any stat(2) calls.
