Tests for bug 2686

[Ann and Jason Edmeades]

Here's some tests which show the problem reported as bug 2686. I tried to
find a way to fix it but its not simple. (Note I can only confirm that XP
behaves as described). 

I'd call this problem a challenge for anyone which understands the heap
management code! Its 'simple' to fix inefficiently (ie add the original size
requested to the allocation header) but this is a real waste of memory since
we store the size rounded up. The problem is we make use of the lower 3
bytes of the size for flags, and ensure the block is of at least a certain
size.

Changelog

Add tests for querying the size of a smaller allocation block.
