  lib-index: Add macros to check if transaction log file version is new enough.

The version numbers are 8bit, so we can generate a single 16bit number out
of them.

  Log Message:
  -----------
  lib-index: Don't increase modseq for backend/dirty flag changes

These flags are used only for internal changes and they shouldn't be
triggering any modseq changes.

To avoid modseqs from unexpectedly shrinking, the new modseq counting
behavior is enabled only for newly rotated transaction log files that have
a new minor_version.
