9f07af6156 init: don't srop unterminated processes' entries during inittab reload
This feature was removed in 72c99af

It is useful when process is removed from inittab and later added
back, but never terminated. It prevents init from spawning duplicate.

d2e07bc16c init: don't use fixed size buffer for command
We store init actions forever. 256 bytes per action means that
a typical inittab of ~10 commands uses 2.5k just to remember
command strings - which are usually _much_ shorter than 256 bytes.

At a cost of a bit more code, it's possible to allocate
only actually needed amount.
