Reminder: committing changesets

[Kevin Rushforth]

As we near the end of the 8u20 release here are a few simple reminders 
of the rules for pushing changesets.

1) Generally all changesets should have a JIRA bug ID associated with 
them. Exceptions are documented on our Wiki [1].

2) The format of commit messages (also on the Wiki) is:

RT-nnnnn: bug title from JIRA
Summary: a description of what or how you fixed the problem  [optional]
Reviewed-by: list, of, reviewers [openjdk ID is preferred]
Contributed-by: Some One <some.one at foo.org>  [if applicable]

3) Avoid unrelated changes in the same changeset

Thanks.
