mysql-test/suite/handler/innodb.result:
  Added test case
mysql-test/suite/handler/innodb.test:
  Added test case

  Settting of active_index is not needed anymore
storage/maria/ma_pagecache.c:
  Added error message if we have too little memory for Maria page cache

  - Added some new safety asserts.

Don't allow too low value of pagecache_buffer_size for mysqld

storage/maria/ha_maria.cc:
  Don't allow too low value of pagecache_buffer_size (as it will stop mysqld from starting)
storage/maria/maria_read_log.c:
  Allow one to decrease page-buffer-size down to 1M (from 128M)

  not take into account that MariaDB's table elimination could eliminate tables
  from join plan (and so, from join nest).
  Fixed the check in the function to compare post-table-elimination numbers.

- Set lastinx= ~0 when last_key.keyinfo is set.


storage/maria/ma_check.c:
  Set lastinx= ~0 when last_key.keyinfo is set
storage/maria/ma_ft_boolean_search.c:

LP#619731: Aria recovery corruption "Page 1: Row: 1 has an extent with wrong information in bitmap

storage/maria/ma_bitmap.c:
  Don't send broadcast if no one is waiting for it
storage/maria/ma_blockrec.c:
  Don't update bitmap if the page is not in the dirty_page list (or LSN is after checkpoint start)
  Fixes the case where we have in the log redo_free_block followed by another redo entry for the same page which is ignored.

  Updated prototype
storage/maria/ma_check.c:
  Added printing of bitmap information if used with maria_chk -vvv (for debugging)

  Updated call parameters to _ma_apply_redo_free_blocks().

The patch also fixes a race in rpl_stop_slave.test.

On machines with lots of CPU and memory, something like `mtr --parallel=10`
can speed up the test suite enormously. However, we have a few test cases
that run for long (several minutes), and if we are unlucky and happen to
schedule those towards the end of the test suite, we end up with most
workers idle while waiting for the last slow test to end, significantly
delaying the finish of the entire suite.

Improve this by marking the offending tests as taking "long", and trying
to schedule those tests early. This reduces the time towards the end of
the test suite run where some workers are waiting with nothing to do for
the remaining workers each to finish their last test.

Also, the rpl_stop_slave test had a race which could cause it to take
a 300 seconds debug_sync timeout; this is fixed.

Testing on a 4-core 8GB machine, this patch speeds up the test suite with
around 30% for --parallel=10 (debug build), allowing to run the entire
suite in 5 minutes.
