[Acl-devel] [RFC] Add attribute visibility("default") to API functions

[Yury Usishchev]

Hello!

I am trying to make acl build with -fvisibility=hidden possible. For that API 
functions (that are used externally)
should be marked with __attribute__((visibility("default"))).
More info on visibility in gcc wiki - https://gcc.gnu.org/wiki/Visibility

I modified macro from above wiki page and added it to headers of acl.
Then I gathered all functions that are accessible externally (from public 
headers that are installed to /usr/include)
and marked them all with new macro. Resulting patch is attached.

Could you please review attached patch?

BR,
Yury Usishchev
