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

It is impossible to formulate sane ABI based on

Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

cba1b96735 Patch from Shaun Jackman to set environment variable RUNLEVEL equal to
init's argv[1], so if you append "single" to your kernel command line and
the kernel doesn't parse it, RUNLELEL=single.

Plus a few unrelated header cleanups while I was in the area...

c58dbf28e0 - remove useless variable "status" from init_main.
http://www.opengroup.org/onlinepubs/009695399/functions/waitpid.html suggests
that we need not specify a status if we don't want, and we don't.
"If wait() or waitpid() return because the status of a child process is available, these functions shall return a value equal to the process ID of the child process. In this case, if the value of the argument stat_loc is not a null pointer, information shall be stored in the location pointed to by stat_loc.  "

3ab3080bc2 - use config_buffer for message()
- add second argument to waitfor(*action,pid); if action==NULL then use pid tor
  wait for. If an action was given, we wait for the action to finish just as
  before. In run() remove second and third occurance of the same functionality
  the waitfor() call now provides.
  Adjust the former only caller of waitfor accordingly.

PS: Not using waitfor but creating a second function used a few bytes more than
simply extending and reusing waitfor.

b3ede5abe2 More from Jan Kiszka: this is a port of the latest sysv-init SELinux patch.
It makes busybox invoke the libselinux library function to load the binary
policy right at system start-up. It was successfully tested on a mini-SELinux
system.  Note: requires recent libselinux. I'm using 1.28.
