[PATCH] Kill unused/useless macros in panoramiX.h: BREAK_IF, IF_RETURN, FORCE_ROOT

[Jamey Sharp]

This header doesn't seem to be used outside the server tree, so I don't
think anything was depending on these except what I've fixed in this
patch.

FORCE_ROOT is not used anywhere, and never has been in all the history
that's in git. ajax removed its FORCE_WIN and FORCE_CMAP companions
three years ago, in 04b87d6dfae02e4ecdb5216d12c6cdafd1e8c2b4.

BREAK_IF and IF_RETURN expanded to exactly the keywords in their names,
which is silly. They were rarely used and served only to make callers
inconsistent with the idioms used elsewhere in the server.
