Rename BlackBerry arm mkspecs to be aligned with NDK structure

The current NDK uses CPUVARDIR variable to define whether x86 or armle-v7 is used.
Therefore, the whole structure uses these two definitions to separate simulator
and device builds. Renaming blackberry-armv7le-qcc to blackberry-armle-v7-qcc
allows to directly use CPUVARDIR during Qt5 builds.
For compatibility reasons the old folder is kept and includes the new qmake.conf.

BlackBerry: improve BPS event lifetime management

In QEventDispatcherBlackberry::select(), if an event handler called
through filterEvent() starts a nested event loop by creating a new
QEventLoop, we will recursively enter the select() method again.
However, each time bps_get_event() is called, it destroys the last
event it handed out before returning the next event.  We don't want it
to destroy the event that triggered the nested event loop, since there
may still be more handlers that need to get that event, once the
nested event loop is done and control returns to the outer event loop.

So we move an event to a holding channel, which takes ownership of the
event.  Putting the event on our own channel allows us to manage when
it is destroyed, keeping it alive until we know we are done with it.
Each recursive call of this function needs to have it's own holding
channel, since a channel is a queue, not a stack.

However, a recursive call into the select() method happens very rarely
compared to the many times this method is called.  We don't want to
create a holding channel for each time this method is called, only
when it is called recursively.  Thus we have the instance variable
d->holding_channel to use in the common case.  We keep track of
recursive calls with d->loop_level.  If we are in a recursive call,
then we create a new holding channel for this run.
