Page allocator moved from pools to IO loops.
...
The resource pool system is highly hierarchical and keeping spare pages
in pools leads to unnecessarily complex memory management.
Loops have a flat hiearchy, at least for now, and it is therefore much
easier to keep care of pages, especially in cases of excessive virtual memory
fragmentation.

For safer memory allocations, resources are bound to loops.
...
Also all loops have their basic resource pool for allocations which are
auto-freed when the loop is stopping.

Memory statistics split into Effective and Overhead
...
This feature is intended mostly for checking that BIRD's allocation
strategies don't consume much memory space. There are some cases where
withdrawing routes in a specific order lead to memory fragmentation and
this output should give the user at least a notion of how much memory is
actually used for data storage and how much memory is "just allocated"
or used for overhead.
Also raising the "system allocator overhead estimation" from 8 to 16
bytes; it is probably even more. I've found 16 as a local minimum in
best scenarios among reachable machines. I couldn't find any reasonable
method to estimate this value when BIRD starts up.
This commit also fixes the inaccurate computation of memory overhead for
slabs where the "system allocater overhead estimation" was improperly
added to the size of mmap-ed memory.
