[svn-r16698] Purpose: Fix bug 503
Description:
Changed Skip list package to use a deterministic skip list. This allows the
skip list package to avoid calling rand() and srand(), even on machines without
rand_r(). There is no longer a p-value or maximum level for skip lists.
Tested: jam, smirom, linew (h5committest)
