[PATCH libdrm 00/24] Annotate private symbols, drop drm_public macro

[Emil Velikov]

Hi all,

As mentioned by Alan, some compilers do not like it when the symbol 
declaration and definition differ wrt their visibility attribute.

Afaict there are three ways to handle this;
 - Add the drm_public macro into the public headers, and annotate the 
declarations.
 - Use version script to limit the exported symbols.
 - Remove the drm_public macro/VISIBILITY_CFLAGS and annotate the 
private symbols.

>From the above three I believe that 3) is the better one as:
 - it does not add drm_public to the library API,
 - does not rely on features that some platform may be missing (or 
require singling out every platform in the configure.ac script).

So I've went ahead with 3), added a few tests and wired them to
`make check' so that one can easily catch problems.

I have checked that the libraries do not export any new symbols and the 
scripts work as intended nearly a dozen times :-)

The whole series can be found in branch reannotate-symbols at
