commit da60b8c117002067e98d0e96e81e671b00fbaeef
Author: Brett Wilson <brettw@chromium.org>

Write allocation context to memlog traces.

The context information is set by PartitionAlloc to save some extra
context for the allocation. This is written to the "types" field of
the trace.

Since the number of parameters to the Export functions was getting
high, this moves most of them into a struct where they can be named.

Currently, no grouping by allocator is done, this will be done in a
followup.
