Currently the sstable reader code is scattered across several source
files as following (paths are relative to sstables/):
* partition.cc - generic reader code;
* row.hh - format specific code related to building mutation fragments
from cells;
* mp_row_consumer.hh - format specific code related to parsing the raw
byte stream;
This is a strange organization scheme given that the generic sstable
reader is a template and as such it doesn't itself depend on the other
headers where the consumer and context implementations live. Yet these
are all included in partition.cc just so the reader factory function can
instantiate the sstable reader template with the format specific
objects.
This patchset reorganizes this code such that the generic sstable reader
is exposed in a header. Furthermore, format specific code is moved to
the kl/ and mx/ directories respectively. Each directory has a
reader.hh with a single factory function which creates the reader, all
the format specific code is hidden from sight. The added benefit is that
now reader code specific to a format is centralized in the format
specific folder, just like the writer code.
This patchset only moves code around, no logical changes are made.
Tests: unit(dev)
