ConfigEngine - when deprecated option for this command is in config,
there should not be warning about it's deprecated, because everything
is in config is optional + unit/integration tests + tests with real config

Fixed possible deadlock in select

seems there was a race condition/deadlock (observed only in ubuntu perl 5.14.2) in select

===
sudo strace -p 22187
Process 22187 attached - interrupt to quit
wait4(-1,

sudo strace -p 22188
Process 22188 attached - interrupt to quit
select(8, [5], NULL, NULL, NULL
===

possible reason is https://rt.perl.org/Ticket/Display.html?id=93428
(seems sometimes select() isn't interruptable)

fixes:

1. before terminating child processes with signal USR2, close all pipes to children.
2. don't use select() in children at all. use blocking read (sysread()) which is interruptible
chnagelog updated
whitespace fixes
wrong comment fixed
fixed meta_decode warnings

meta_decode was issuing warnings (not initialized values) when input was empty string,
string with spaces-only, string with correct marker but without real data
