RFR: JDK-8268241: deprecate JVMTI Heap functions 1.0

[Serguei Spitsyn]

The JVM TI Heap functions 1.0 were superseded by newer functions in JVM TI 1.2 (Java 6) and should be deprecated so they can be removed in a future release.

We need to replace this sentence:
"These functions and data types were introduced in the original JVM TI
version 1.0 and have been superseded by more powerful and flexible
versions which:"
with:
"These functions and data types were introduced in the original JVM TI
version 1.0. They are deprecated and will be changed to return an error
in a future release. They were superseded in JVM TI version 1.2 (Java 6) by more powerful and flexible versions which:" 

The CSR has been approved:
