Log message (13 lines):
common/stats.h,include/xapian/enquire.h,matcher/localmatch.cc,
matcher/weight.cc: Undo ABI change introduced in previous commit
with a nasty workaround; we can't initialise Weight::internal
reliably, because applications complied with earlier versions of
the library may have inlined the constructor of the Weight class.
Therefore, we can't delete Weight::internal in the destructor,
because we don't know if it was initialised.  Instead, we
add factory methods for making Weight::Internal objects to Stats,
register all the Weight::Internal objects made by these factory
methods in a list is the Stats object, and delete them when Stats
is deleted (which conveniently happens after the match has
finished).  Mark all this with FIXME:1.1: so that we can easily
convert it to nicer code once we branch for 1.1.
