made "test" an ash built-in.

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.

for use as a rescue shell, in the event that you screw up your system.
Note that this will *also* cause applets to take precedence
over shell builtins of the same name. So turning this on will
eliminate any performance gained by turning on the builtin "echo"
and "test" commands in ash.
Note that when using this option, the shell will attempt to directly
run '/bin/busybox'. If you do not have the busybox binary sitting in
that exact location with that exact name, this option will not work at
