This patchset fixes a bug in SSTables 3.x reading when fast-forwarding
is enabled. It is possible that a mutation fragment, row or RT marker,
is read and then stored because it falls outside the current
fast-forwarding range.
If the reader is further fast-forwarded but the
row still falls outside of it, the reader would still continue reading
and get the next fragment, if any, that would clobber the currently
stored one. With this fix, the reader does not attempt to read on
after storing the current fragment.
Tests: unit {release}

* 'projects/sstables-30/row-skipped-on-double-ff/v2' of https://github.com/argenet/scylla:
tests: Add test for reading rows after multiple fast-forwarding with SSTables 3.x.
sstables: mp_row_consumer_m to notify reader on end of stream when storing a mutation fragment.
sstables: In mp_row_consumer_m::push_mutation_fragments(), return the called helper's value.

./build/release/scylla --help
Building Fedora RPM
As a pre-requisite, you need to install Mock on your machine:
# Install mock:
sudo yum install mock
# Add user to the "mock" group:
usermod -a -G mock $USER && newgrp mock
Then, to build an RPM, run:
./dist/redhat/build_rpm.sh
The built RPM is stored in /var/lib/mock/<configuration>/result directory.
For example, on Fedora 21 mock reports the following:
INFO: Done(scylla-server-0.00-1.fc21.src.rpm) Config(default) 20 minutes 7 seconds
INFO: Results and/or logs in: /var/lib/mock/fedora-21-x86_64/result
Building Fedora-based Docker image
Build a Docker image with:
cd dist/docker
docker build -t <image-name> .
Run the image with:
docker run -p $(hostname -i):9042:9042 -i -t <image name>
