clib2 Code

- Added a couple more program names to the list.

- Added the global variable __expand_wildcard_args which can be used
to disable wildcard pattern expansion of command line parameters when
linked against "libunix.a". Note that this has no effect on the "regular"
libc.a behaviour.

- Added the rand() test program.

This commit was manufactured by cvs2svn to create tag 'V1_200'.

- Preparations for new release.

- Replaced an inappropriate "ULONG" with "unsigned long".

- Changed wait_select() to waitselect().

- The default break signal mask (SIGBREAKF_CTRL_C) is no longer
hard-coded. You can override it at link time with a different
variable value for __break_signal_mask. This may have to be
augmented by an API for changing the value.

- Disabled the thread-safe build.

- Corrected the lock variable name.
