Axel Dörfler 0ec4af2233 Improved AreaPool to have an initial size as well as well as a name that is
used for new area.
MemPool::AddToPool() now gracefully deals with NULL pointers (or a size of 0).
BitmapManager was deleting the area it transferred to AreaPool before - it
no longer needs an extra area, though.
Minor other cleanup.

\brief Handler for BBitmap allocation
Whenever a ServerBitmap associated with a client-side BBitmap needs to be
created or destroyed, the BitmapManager needs to handle it. It takes care of
all memory management related to them.
NOTE: The allocator used is not thread-safe, it is currently protected
by the BitmapManager lock.
