* Removed the old AS_AREA_MESSAGE stuff - it's currently not used at all, and
even though we might need something similar, we can't use it (since it was based on BGet++). * Removed BGet++, it's not used anymore. * Removed ServerMemIO class, was never used. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16830 a95241bf-73f2-0310-859d-f6bbb57e9c96

BGET pool allocator

This class is based on the BGET pool allocator. Original code was in standard

ANSI C with a bunch of static variables. The original code was placed into the

MemPool class and the original allocation, release, and compacting functions
|
||||
were made into virtual members. MemPool also, unlike the original code, makes
|
||||
use of malloc() and free() to handle dynamic memory needs. AreaPool is a MemPool
|
||||
subclass which uses areas to handle memory management needs in large chunks.
