clib2 Code

- Added HUGE_VALF to <math.h>.

- The printf() family now supports the %hh, %j, %t and %z modifiers and the
%a/%A conversions for C99. The %j is treated like %ll, %t and %z are treated
like %l.

- Plugged in the proper ISO 8601 week number calculation function.

- strftime() now ignores the E and O modifiers.

- Added strtof(), llabs(), lldiv(), vsscanf() and vscanf() for C99.

- strftime() now supports %C, %n, %r, %R, %t, %T, %u, %V, and %z for C99.

- The libunix.a flavour of system() no longer attempts to translate the name
of a command unless it contains path separator characters.

- Fixed a typo in the semaphore creation code. Ouch.

- If fread()/fwrite() fail to read/write any data because either the number
of records or the size of each record is zero, both now call clearerr() to
avoid giving the caller the wrong impression that an EOF or error occured.

- Fixed two linker errors which were caused by duplicate symbol definitions.

- Added code to the startup routine which allows you to monitor where command
was started from and which parameters it was invoked with.
