RFR (S/T): 8231737: Cleanup JvmtiRawMonitor code

[David Holmes]

Bug: https://bugs.openjdk.java.net/browse/JDK-8231737
webrev: http://cr.openjdk.java.net/~dholmes/8231737/webrev/

Stylistic code cleanup of JvmtiRawMonitor code as previously promised:
- Self -> self
- SimpleX -> simpleX
- Contended -> contended
- Node -> node
- TState -> tState (variable name)
- _WaitSet -> _waitSet
- _EntryList -> _entryList;
- All -> all
- remove extra space before ( in function calls
- remove extra space before ;
- remove extra space before ++ and --
- add spaces around binary operators
- use { } on all blocks
- use one statement per line.
- fix indent and alignment (ie remove artificial alignment)

Probably simplest to look at new code and see if it looks okay rather 
than trying to spot each individual change. :)

Thanks,
David
