mem-pool: add tracking of mem_pool that requested the allocation

This renames the current 'struct mem_pool' to 'struct mem_pool_shared'.
The mem_pool_shared is globally allocated and not specific for
particular objects.

A new 'struct mem_pool' gets allocated when mem_pool_new() is called. It
points to the mem_pool_shared that handles the actual allocation
requests. The 'struct mem_pool' is only used for accounting of the
objects that the caller requested and free'd.

All of these changes will be used to collect all the memory pools a
glusterfs_ctx_t is consuming, so that statedumps can be collected per
context.
