Remove the recently added USE_SEGMENTED_FILES option, and indeed remove all
support for a nonsegmented mode from md.c. Per recent discussions, there
doesn't seem to be much value in a "never segment" option as opposed to
segmenting with a suitably large segment size. So instead provide a
configure-time switch to set the desired segment size in units of gigabytes.
While at it, expose a configure switch for BLCKSZ as well.
