adjust SEL_TREE::keys_map appropriately.

- Added more comments.
- Added a RANGE_OPT_PARAM::remove_jump_scans flag that disables construction of index_merge
  SEL_TREEs that represent unusable conditions like "key1part1<c1 OR key2part2<c2"
- make prune_partitions() function handle the case where range analysis produces a list of 
  index_merge trees (it turned out that this is possible, appropriate test case added).
- Other small fixes.

Restore "make dist" for the header files in "storage/innobase/include".


storage/innobase/Makefile.am:
  A recent change (coming from the "innobase" team, pushed by alexi) broke "make dist"
  which is needed for release builds (deletion of "storage/innobase/include/Makefile.am").
  The effect was that files "storage/innobase/include/*.h" were missing in the source.tgz
  
  Restore "make dist" without fully reverting the change by listing the files in a (new)
  "EXTRA_DIST" target in the parent level directory.
