[PATCH] Much simpler fix to commit failure via out of date proxy

Hi All

Mike has suggestion at [1] to make use 'DAV:apply-to-version' to avoid
the problematic PROPFIND altogether.

This suggestion works very well.

It is just the ra_neon fix i.e no mod_dav_svn fix

Attached patch implements this fix.

All tests pass with this test(except the known mergeinfo test 8 failure.)

In next few hours I will commit this as it looks fairly obvious unless
there are some objections.

Thanks Mike,

With regards
Kamesh Jayachandran
