Hi all,

As part of an attempt to make it easier for G1 to contain multiple collector policies I suggest that the collection set code should be moved out of the current G1 collector policy class into a class of its own.

I've tried to hold back on doing further cleanups in this patch in order to make it easier to review the changes.

I do have some ideas on how the collection set code could be further cleaned up but I'm not sure if I will have time to test them properly before FC.

Webrev: http://cr.openjdk.java.net/~mgerdin/8151178/version1/webrev_full

I've also split the change into three webrevs in the version1 directory: webrev_1 consists of moving the code and changing code accessing collection set related methods webrev_2 consists of renaming almost all methods in the new class to not contain redundant collection set naming webrev_3 restores the functionality for collector policy extensions to hook into collection set selection.

Bug: https://bugs.openjdk.java.net/browse/JDK-8151178

Testing: JPRT, RBT GC testing.

Thanks6 /Mikael
