RFR(XL): 8199712: Flight Recorder

[Erik Gahlin]

Here is an updated webrev:

http://cr.openjdk.java.net/~egahlin/8199712.1/ [1]

that incorporates:

- build changes
- new event prefix, i.e. "com.oracle.jdk.CPULoad" becomes "jdk.CPULoad"
- obsolete command line options EnableTracing and UseLockedTracing
- fixed typos in the Javadoc
- simplified #include files

RFEs have been filed for other issues, CSR is approved and tests pass.
