QMap: deprecate insertMulti, unite and friends

Browse Source 
insertMulti and unite will silently transform a QMap into a multi-map
which is not behavior we want to keep around anymore and as such is
being deprecated. QMap functions that only make sense in a multi-map
scenario are also deprecated and the implementation is moved to
QMultiMap where it makes sense.

Use QMultiMap if multiple keys are desired and insert(const QMap &)
if a non multi-map-converting unite is desired.

[ChangeLog][QtCore][QMap] insertMulti(), unite(), values(Key),
uniqueKeys(), count(Key) is now deprecated. Please use
QMultiMap instead.

QMultiMap\<Key, T\> is one of Qt's generic \l{container classes}.
It inherits QMap and extends it with a few convenience functions
that make it more suitable than QMap for storing multi-valued
maps. A multi-valued map is a map that allows multiple values
with the same key; QMap normally doesn't allow that, unless you
call QMap::insertMulti().
It inherits QMap and extends it with a few functions
that make it able to store multi-valued maps. A multi-valued map
is a map that allows multiple values with the same key; QMap
doesn't allow that.
Because QMultiMap inherits QMap, all of QMap's functionality also
applies to QMultiMap. For example, you can use isEmpty() to test
whether the map is empty, and you can traverse a QMultiMap using
QMap's iterator classes (for example, QMapIterator). But in
addition, it provides an insert() function that corresponds to
QMap::insertMulti(), and a replace() function that corresponds to
QMap::insert(). It also provides convenient operator+() and
operator+=().
addition, it provides an insert() function that inserts but does
not overwrite any previous value if the key already exists,
and a replace() function that corresponds which does overwite
an existing value if they key is already in the map.
It also provides convenient operator+() and operator+=().
