clib2 Code

- Moved the Workbench console stream initialization into the
initialization code for the stdin/stdout/stderr streams and
out of the program parameter setup.

- The current program name is now set up in the stdlib
initialization function.

- Simplified the machine test code; moved the FPU check into
the math initialization code.

- Added more safety checks to verify that file descriptor
file handles are valid.

- Corrected the names of macros.

- DoTimer() now calls AllocSysObject() rather than making up
a MsgPort locally.

- The record locking semaphore code now builds a semaphore to add
before it tries to find the public one in memory. That way, the
code can spend less time in Forbid() state and, heaven forbid,
refrain from allocating memory while in that state.

- Replaced the plain text documentation with HTML versions.

- Fixed a compiler problem in the socket setup.

- Feature freeze!

- In the thread-safe variant, the library now tries to allow
multiple concurrent callers to use the socket functions. Note
that this works only with the Roadshow TCP/IP stack, and the
results with other TCP/IP stacks are rather unpredictable.

- Rewrote the code that allocates the file descriptor and file
buffer tables so that all the memory allocations are in one
place and it's possible to specify exactly how many table
entries are required at a time.

- Creation and initialization of semaphores now uses the AmigaOS4
specific functions for this purpose, if available.

- Added a very simple test program, just to see how much of the library
it will pull in when linked.

- Added uname command, as contributed by Peter Bengtsson. Thank you very much!
