The following patches contain fixes for skipping to the next parititon
in multi_range_reader and completelty dissable support for fast
forwarding inside a single partition, which is not needed and would only
add unnecessary complexity.
* https://github.com/pdziepak/scylla.git fix-multi_range_reader/v1:
flat_multi_range_mutation_reader: disallow
streamed_mutation::forwarding
flat_multi_range_mutation_reader: clear buffer on next_partition()
tests/flat_multi_range_mutation_reader: test skipping to next
partition
Using Materialized Views, if the base table has static columns,
and the update in base table mutates static and non static rows,
the streamed_mutation is stopped before process non static row.
The patch avoids stopping the stream_mutation and adds a test case.

end_bound was not updated in one of the cases in which end and
end_kind was changed, as a result later merging decision using
end_bound were incorrect. end_bound was using the new key, but the old
end_kind.
Fixes#3083.

"Currently, compaction manager will serialize compaction of same size tier
(or weight) if they belong to the same column family. However, it fails to
do so if the compaction jobs belong to different column families.
That can lead to an ungodly amount of running compaction which gets worse
the higher the number of shards and active column families. The problem
is that it may affect overall system performance due to excessive resource
usage. It's easy to trigger it during bootstraping after loading node with
new sstables or repairing, or if lots of cfs are being actively written."
Fixes#1295.
* 'similar_sized_compaction_serialization_v4' of github.com:raphaelsc/scylla:
sstables: remove column_family from compaction_weight_registration
compaction_manager: serialize compaction of same size tier for different cfs
sstables: introduces deregister() and weight() to compaction_weight_registration
sstables: move compaction_weight_registration to its own header
sstables: improve compact_sstables() interface
Starting with commit fb0866ca20, tests
do not have to, and MUST NOT, define the disk error handlers. If they
do, we get a re-definition of variables already defined in
disk-error-handler.cc.
tests/hint_test.cc was apparently written before that commit, so we
need to remove the duplicate variables to get it to link.

Motivation is that a new field in the descriptor will be forwarded
to compaction procedure without extending parameter list even more.
Also beautifies the interface, making it concise and easier to
play with.

"Fixes #3057."
* 'summary_recreation_fixes_v2' of github.com:raphaelsc/scylla:
tests: sstable summary recreation sanity test
sstables: make loading of sstable without summary to work again
sstables: fix summary generation with dynamic index sampling
All users of the filtering reader need only the decorated key of a
partition, but currently the predicate is given a reference to
streamed_mutations which are obsolete now.
A user with DESCRIBE on the root role resource can list any roles of any
roles, and also the roles in the system.
Otherwise, a user can list all the roles it has been granted and can
list all roles granted to those roles.
A role can be dropped if the performer has DROP permission on the role.
A role that has superuser (either directly or through another role
it has been granted) cannot be dropped except by a superuser.
Only superusers can alter superuser status, but only to roles not
granted to them. You can always alter your own role. You can alter
another role if you have ALTER permission on the role.
CREATE ROLE requires CREATE on <ALL ROLES>. Creating a superuser role
requires that the performer is a superuser.
This change also forms the beginning of a test suite for the CQL
interface to roles. We start with verifying access-control properties of
CREATE ROLE as written in this patch.
The auth service will eventually add the default
superuser ("cassandra"), but the current code does so after a delay.
Using a dedicated superuser for unit tests side-steps the issue and
allows the user to be created immediately.
"The changes in this series fall into one of the following:
1) improve unit tests
2) improve code reuse in mvcc so that later cahnges will be easier
3) fix minor issues which were exposed by the above"
