This reverts commit 36a86e50.

Turns out this needs more work than expected.  hash_part_inx is used
afterwards and HASH_FCN no longer uses/sets it.

For future reference it looks like in the new code you would just
call HASH_TO_BKT after calling HASH_FCN.  I didn't want to spend
time testing it, so just rolled back the code.  As this is the only
place in the entirity of Slurm we currently use it I am not super
concerned.

NOTE: the macro HASH_FCN (which is really HASH_JEN) is identical in
both places outside the already explained differences.

When set, do not flush the Lustre cache through the alpsc_flush_lustre()
call, and do not drop caches through /proc/sys/vm/drop_caches either.

This avoids a potential source of SIGBUG errors for other jobs sharing
the node.

Move "burst_buffer" from individual command data structures (srun_opt
  and salloc_opt) to common slurm_options. This is desired to have
  sbatch command support --bb option.

This patch fix commit b31bb7 for big-endian machines inverting the
__builtin_clzll and __builtin_cltll calls depending on the architecture.
This caused to get the incorrect first and last bit set on the bitmap in
bit_ffs bit_fls.

upon random errno value.
