Let projection be done before sorting

When sorting, a row needs to be compared with other
rows quickly and multiple times. To facilitate this,
force projection to happen, so sorting doesn't have
to execute an expression for every comparison.

Store resolved ids for label, property names, and rel types in semantic table rather than ast
Sort files to make it easier to find the correct files in the log. Specifically, it should be easy to see what logical logs are available, and what sizes they have. Without this it's pretty darn hard.

Introduces handling of records that are not interesting for rolling upgrades

While nodes and relationships should be handled specially, the rest of the
 records that can be present in a transaction should be passed as is. This
 commit takes care of that, along with tests.
Fixes node record management to allow for changes in labels and properties
 without any other changes in the transaction. Tests for those, as well as
 some necessary test harness.
