Proposal: Add #define to show new API element is available

I've just been adding code to deal with detecting new API functions.
I've ended up with code like this:

#if (SVN_VER_MAJOR == 1 && SVN_VER_MINOR >= 1) || SVN_VER_MAJOR > 1
#define PYSVN_HAS_CLIENT_ADD2
#define PYSVN_HAS_CLIENT_EXPORT2
#endif

#if (SVN_VER_MAJOR == 1 && SVN_VER_MINOR >= 2) || SVN_VER_MAJOR > 1
#define PYSVN_HAS_CLIENT_INFO
#endif

What would have made this all a lot easier is if the feature test
macros where
defined in the SVN headers.

In svn_client.h how about having

#define SVN_HAS_CLIENT_ADD2

Then code that builds on top of svn can test for features and avoid the
version testing code.
