flush committed buffer only
Read back all data from mmapd file in serdebug
No need for clear_committed(), but we need to re-write the last object we were writing before the buffer overflow
(de)serialize ways and relations, too (no nodes/members yet)
dump usernames, too
support for (de)serializing node lists in ways
Towards a better way to access objects in buffers...
simplified cast madness
More cast simplifications
Simplified node parsing code
make padded_length free function
more simplification parsing ways/relations
more refactoring
Cleanup internal ptr calc
buffer item cleanup
refactored Tag* stuff
finished tag stuff refactoring
Refactoring nodes in ways
use static_cast instead of reinterpret_cast where possible
