Paulius Zaleckas 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.

Denys Vlasenko 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.

Denis Vlasenko 084266ed52 fix several problems with config parser:
a bug where it underflows the string
 a bug where it never frees parser_t struct
make read_config() return 0 if parser is NULL,
 make config_close() accept and ignore NULL parser -
 eliminates many if() blocks
reverse the sense of parser bit flags - negative flags
 are harder to grok.
hexdump: revert the change to use config parser, it is BIGGER
 and also requires additional quirks in parser
*: explicitly use PARSER_NORMAL instead of 0

Bernhard Reutner-Fischer 54d50a0b47 - fix "noreduce" flag of config_read (didn't work at all, at least for me).
- convert init's inittab parsing to the new config parser:
