Hello,
this patch fixes __attribute__ ((hidden)) use.  The 
hidden_def(SYM)/hidden_proto(SYM) pair should be used for symbols that 
are a part of the public API; it creates hidden aliases (SYM_internal) 
for use within the shared library, which speeds up both dynamic linking 
and code execution.  Symbols that are not in the public API should use 
"hidden" in the function declaration.

This patch replaces all incorrect uses of hidden_def/hidden_proto by 
"hidden" (some uses in lib/private.h are left because these symbols used 
to be declared in libaudit.h).  It also adds hidden_def/hidden_proto 
macros to those public symbols that are referenced from within the 
libraries.
