Added doxygen-style comments to several functions.

Added doxygen-style comments to several functions.

Also, in oilsAuthInit():

1. Moved the declarations of several variables closer to their first uses.

2. Instead of using va_list_to_string() to build a seed, exploit the fact that
md5sum() builds its input using printf-style formatting.  This change eliminates
a malloc(), a free(), and two calls to vsprintf().
