Provide DLLEXPORT markers for C functions via PG_FUNCTION_INFO_V1 macro.

Second try at the change originally made in commit 8518583cd;
this time with contrib updates so that manual extern declarations
are also marked with PGDLLEXPORT.  The release notes should point
this out as a significant source-code change for extension authors,
since they'll have to make similar additions to avoid trouble on Windows.

Laurenz Albe, doc change by me
