just build relevant source and use xxx_main functions.
build system: add a special case when we have exactly one applet enabled
(makes "true", "false", "basename" REALLY tiny).
getopt32: do not use stdio.

moved the contents of libbb/bb_echo.c back into coreutils/echo.c,
which is a more reasonable place for them than libbb. this
forces anyone who wants echo and test to be builtin to ash to
also have them available as applets. their cost is very small,
and the number of people who wouldn't want them as applets is
also very small.
added warning about shell builtins vs. CONFIG_FEATURE_SH_STANDALONE_SHELL,
which conflicts with their use.
thanks to nathanael copa for debugging help.
some string size optimization in test.c may have been lost with
this commit, but this is a good new baseline.

definitions. (That should only be on prototypes.)

echo applet into libbb, and now call bb_echo() from both echo.c
and ash.c

This is a bulk spelling fix patch against busybox-1.00-pre10.
If anyone gets a corrupted copy (and cares), let me know and
I will make alternate arrangements.
Erik - please apply.
Authors - please check that I didn't corrupt any meaning.
Package importers - see if any of these changes should be
passed to the upstream authors.
I glossed over lots of sloppy capitalizations, missing apostrophes,
mixed American/British spellings, and German-style compound words.
What is "pretect redefined for test" in cmdedit.c?
Good luck on the 1.00 release!

cleans up most of the now-revealed problems.

header file usage before the 0.49 release. To fix it, I had to move
the '#include "busybox.h"' to the end of the list of #include files.

busybox.h which slowed compiles. I left only what was needed and then fixed up
all the apps to include their own header files. I also fixed naming for pwd.h
and grp.h functions. Tested to compile and run with libc5, glibc, and uClibc.

escape seq. code from tr and echo into utility.c. Fix thanks to
Matt Kraai <kraai@alumni.carnegiemellon.edu>.
* This should close Bug #1015. Please test.

Tested under both libc5 and libc6 and all seems well with these fixes.

* zcat works again (wasn't working since option parsing was broken)
