The class `GzipRandomAccess` is used to parse heap dump file generated from
`jcmd`/`jmap` tools when testing.
It has the limitation that only gzip file which has "blocksize" header field
could be sucessfully parsed.
We think this class can be removed for 2 reasons:
1. The gzip heap dump file gene
Partition safepoint checking and nonchecking lock ranks. The nonchecking locks
are always lower ranked than the safepoint checking locks because they cannot
block.
This moves some leaf locks to 'nosafepoint' rank and corrects relative ranking.
Tested with tier1-6 and built and run tier1 tests w
This change removes the special ranking and folds it into nosafepoint. You
have to look at commit #3 to see this actual part of the change that doesn't
include JDK-8273915.
This passes tier1-6 also.

Fixing failing regression tests caused by the JEP 400: UTF-8 by Default.
`JcmdOutputEncodingTest` test case uses `file.encoding=UTF-8` in `C` locale.
The output from the agent library is in `UTF-8` so it succeeded before the JEP
has been implemented, as System.out used `UTF-8` converter. After t
The changes fixes discovered issues with getEventSetForThreadStartDeath method
and its callers:
- getEventSetForThreadStartDeath must resume suspended thread(s), otherwise it
can never get desired event;
- callers should not call addCountFilter;
also simplifies getEventSetForThreadStartDeath.

pass along my comments so far. Overall it looks good though.
