clib2 Code

- Modified the GetProcSegList() call to match what the current SDK
expects.

- Moved an allocation size roundup operation in realloc().

- Added lockf() support, as supplied by Henning Nielsen Lund.
Thank you very much!

- symlink() now also works for absolute and relative links, and is
part of "libunix.a". This patch was supplied by Henning Nielsen Lund.
Thank you very much!

- More corrections and clarifications.

- Updated the copyright text.

- The printf() family stripped trailing zeroes from the integer part
of %g output. Fixed.

- Added "factorial" test program for "%g" testing.

- The __main() stub function expected by the 68k GCC build is no
longer part of "stdlib_main.c". This helps the C++ support, since the
__main symbol definition no longer clashes with the definition in
"libgcc.a".

- Preparations for release.

- Forgot to check in a file.
