Hello Mike!

I prepared 4 patches:

0001-Rework-config.h-usage.patch - move #include "config.h" from misc.h to 
every source file.
  Note that I had to change 'libacl/perm_copy.h' as it is included first in 
many sources by build command.
  Also I patched sources in 'test' directory, and I am not sure if it should be 
done:)

0002-Add-acl-libacl.h-include-where-needed.patch
  To address problem with undefined reference I added explicit #include 
<acl/libacl.h> to each source file with
  definitions of functions declared in 'include/libacl.h'.

0003-Add-sys-acl.h-include-where-needed.patch
  Same for 'sys/acl.h'.
  This patch is not required, in all cases it was included implicitly by 
#include "libacl.h" or #include <acl/libacl.h>
  Also this patch may look better if merged with previous one.

0004-Add-visibility-default-attribute-for-api-functions.patch
  Change of visibility, as discussed previously :)

Can you review them please?
