HprofRecordReader

[jvm]\ class HprofRecordReader

Reads hprof content from an Okio BufferedSource.

Binary Dump Format reference: http://hg.openjdk.java.net/jdk6/jdk6/jdk/raw-file/tip/src/share /demo/jvmti/hprof/manual.html#mozTocId848088

The Android Hprof format differs in some ways from that reference. This parser implementation is largely adapted from https://android.googlesource.com/platform/tools/base/+/studio-master-dev /perflib/src/main/java/com/android/tools/perflib

Not thread safe, should be used from a single thread.
