Initial import of picoc-2.1 into the Packages Collection

	PicoC is a very small C interpreter for scripting.  It was originally
	written as the script language for a UAV's on-board flight system.
	It's also very suitable for other robotic, embedded and non-embedded
	applications.

	The core C source code is around 4000 lines of code.  It's not
	intended to be a complete implementation of ISO C but it has all the
	essentials.  When compiled it only takes a few k of code space and is
	also very sparing of data space.  This means it can work well in small
	embedded devices.  It's also a fun example of how to create a very
	small language implementation while still keeping the code readable.

	picoc has been tested on x86-32, x86-64, powerpc, arm, ultrasparc,
	HP-PA and blackfin processors and is easy to port to new targets.

To show it working on the old DECUS grep program (included as one of its
tests):

	% time picoc work/picoc/tests/46_grep.c - case work/picoc/tests/46_grep.c
	File work/picoc/tests/46_grep.c:
	"lower-case are always ignored.  Blank lines never match.  The expression",

	      case '^':

	      case '$':

	      case '.':

	      case '[':

	      case ':':
	...
