Change hprof to use streaming
Previously, we compute the whole hprof dump in memory resulting in
> 50MB of memory usage for some apps (such as maps). This could
cause the app to get killed by the low memory killer.
The solution works by doing the dump in 2 passes.
The first pass calculates the size of the dump.
The second pass starts by sending the DDMS header with the correct
size, then does the rest of the hprof dump by streaming and sending
data one HprofRecord at a time.
