- Introduced val_int_endpoint() function which converts between func
argument intervals and func value intervals for monotonic functions.
- Made partition interval analyzer use part_expr->val_int_endpoint()
to check if the edge values should be included.

Final patch
-----------
This WL is about using this bitmap in all parts of the partition handler.
Thus for:
rnd_init/rnd_next
index_init/index_next and all other variants of index scans
read_range_... the various range scans implemented in the partition handler.
Also use those bitmaps in the various other calls that currently loop over all
partitions.
mysql-test/r/partition_pruning.result:
WL# 2986
New results reflecting bitmap being used to determine if a partition is to be
included
mysql-test/t/partition_pruning.test:
WL# 2986
New tests to show bitmap being used in ha_partition
sql/ha_partition.cc:
WL# 2986
Used work from 2682 and removed the partition select code.
Added do {} while loop to any iteration over partitions to now utilise
m_part_info->used_partitions bitmap to determine if a partition should be
used.

Changed < to <=, which fixes the problem with edge cases going awry.
- post-...-post review fixes

by finding used partitions for a, a+1, a+2, ..., b-1, b.
