can figure out what header files to include, and override stuff that comes
later. But applets shouldn't include platform.h directly, they should include
busybox.h or libbb.h. Since busybox.h already includes libbb.h, move libbb.h
to the top of busybox.h and platform.h near the top of libbb.h (right after
bbconfig.h, which is something platform.h also needs access to).
While we're at it, move some stuff from busybox.h to libbb.h so we have one
big file to audit/clean up/try to make sense of instead of many.
the following of which (from cat.c) belongs in svn history instead of the
source code:
/* Mar 16, 2003 Manuel Novoa III (mjn3@codepoet.org)
*
* This is a new implementation of 'cat' which aims to be SUSv3 compliant.
*
* Changes from the previous implementation include:
* 1) Multiple '-' args are accepted as required by SUSv3. The previous
* implementation would close stdin and segfault on a subsequent '-'.
* 2) The '-u' options is required by SUSv3. Note that the specified
* behavior for '-u' is done by default, so all we need do is accept
* the option.
*/
This needs a second pass to:
+ add bb_daemon(unsigned char no_chdir, unsigned char no_close, const char*flag)
+ eventually globally export argc and argv, so we don't need to pass it to
bb_daemon().
That says use 900k chunks when compressing, which needs about 4 megs of data
structures to undo the Burrows-Wheeler transform. Switching it down to
bzip -1 (100k chunks) should have no impact on the compression (since it
still all fits in one chunk) but should reduce runtime decompression memory
requirements to something like 500k. Still larger than gunzip, but not
egregiously so.
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. "

- 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.

bloatcheck is completely useless as it sees -79 for this, which is bogus.
files still using them. I didn't remove them from e2fsck.c to avoid stomping
pending cleanup patches from Garrett, and I didn't bother to remove them from
fdisk.c because that entire file needs to be rewritten from scratch.
