Monty 0b7b5cc1b3 MDEV-24 Segmented key cache for Aria
Added option 'aria-pagecache-segments', default 1.

For values > 1, this split the aria-pagecache-buffer into the given
number of segments, each independent from each other.  Having multiple
pagecaches improve performance when multiple connections runs queries
concurrently using different tables.

Each pagecache will use aria-pageache-buffer/segments amount of
memory, however at least 128K.

Each opened table has its index and data file use the segments in a
a round-robin fashion.

Internal changes:
- All programs allocating the maria pagecache themselves should now
  call multi_init_pagecache() instead of init_pagecache().
- pagecache statistics is now stored in 'pagecache_stats' instead of
  maria_pagecache. One must call multi_update_pagecache_stats() to
  update the statistics.
- Added into PAGECACHE_FILE a pointer to files pagecache. This was
  done to ensure that index and data file are using the same
  pagecache and simplified the checkpoint code.
  I kept pagecache in TABLE_SHARE to minimize the changes.
- really_execute_checkpoint() was update to handle a dynamic number of
  pagecaches.
- pagecache_collect_changed_blocks_with_lsn() was slight changed to
  allow it to be called for each pagecache.
- undefined not used functions maria_assign_pagecache() and
  maria_change_pagecache()
- ma_pagecaches.c is totally rewritten. It now contains all
  multi_pagecache functions.

Errors found be QA that are fixed:

           multiple segments is not very user-friendly
