[PATCH] rev svn_wc_status2_t to svn_wc_status3_t

Hi!

This is a _big_ patch but it does very little. I've just replaced every
occurence of svn_wc_status2_t with the new svn_wc_status3_t. It's
needed, in the cause of removing the entry field which I intend to do in
a follow-up. There's a WIP on the list, that handles most of the chores of the
status->entry.

Hopefully someone will not be put of by this gigantic blob. If we hadn't
already revved svn_wc_status3() for 1.7 I could have done the compat
wrappers and declarations in one patch and update the callers in a
follow-up. But since it was already revved, here you go! :)

make check passed.

[[[
As part of replacing the entries field in svn_wc_status2_t for WC-NG, we
rev it to svn_wc_status3_t. No semantic changes, except for adjusting some
compat wrappers, else just revving.

As for now, the compat wrappers just casts to the previous type. Some more
magic will be needed when we're ready to throw away that pescious entry field.
