Updates to the bitmap flush/pin logic to prepare for when we support
multiple writers.


storage/maria/ma_bitmap.c:
  Read lock is less bad than write lock.
  Changing bitmap->flushable to a counter, to prepare for when multiple
  writers are allowed on a table.
  Using bitmap->flush_all_requested instead of share->in_checkpoint; the
  latter can be true for the time of a whole checkpoint even though
  the checkpoint is not yet handling our table, or has already handled it,
  so to decrease the number of broadcasts we use a dedicated my_bool
  which is true only when checkpoint is handling this table's bitmap.
  _ma_bitmap_flushable(share,+1) waits for a concurrent _ma_bitmap_flush_all()
  to finish before incrementing non_flushable; without this, with multiple
  writers there may always be one thread making the bitmap unflushable
  and thus checkpoint would stall.
storage/maria/ma_blockrec.c:
  update to new prototype: "flushable is FALSE|TRUE" becomes "add 1|-1 to
  non_flushable".
storage/maria/ma_blockrec.h:
  new prototype
storage/maria/maria_def.h:
  MARIA_FILE_BITMAP::flushable becomes a counter.
  New MARIA_FILE_BITMAP::flush_all_requested.

* fix for bitmap vs checkpoint bug which could lead to corrupted
tables in case of crashes at certain moments: a bitmap could be flushed
to disk even though it was inconsistent with the log (it could be
flushed before REDO-UNDO are written to the log). One bug remains, need
code from others. Tests added. Fix is to pin unflushable bitmap pages,
and let checkpoint wait for them to be flushable.
* fix for long_trid!=0 assertion failure at Recovery.
* less useless wakeups in the background flush|checkpoint thread.
* store global_trid_generator in checkpoint record.


mysql-test/r/maria-recovery.result:

mysql-test/t/maria-recovery.test:

storage/maria/ma_bitmap.c:
  When we send a bitmap to the pagecache, if this bitmap is not in a
  flushable state we keep it pinned and add it to a list, it will be
  unpinned when the bitmap is flushable again.
  A new function _ma_bitmap_flush_all() used by checkpoint.
  A new function _ma_bitmap_flushable() used by block format to signal
  when it starts modifying a bitmap and when it is done with it.
storage/maria/ma_blockrec.c:
  When starting a row operation (insert/update/delete), mark that
  the bitmap is not flushable (because for example INSERT is going
  to over-allocate in the bitmap to prevent other threads from using
  our data pages). If a checkpoint comes at this moment it will wait
  for the bitmap to be flushable before flushing it.
  When the operation ends, bitmap becomes flushable again; that
  transition is done under the bitmap's mutex (needed for correct
  synchro with a concurrent checkpoint); but for INSERT/UPDATE this
  happens inside _ma_bitmap_release_unused() at a place where it already
  has the mutex, so the only penalty (mutex adding) is in DELETE and UNDO
  of INSERT. In case of errors after setting the bitmap unflushable,
  we must always set it back to flushable or checkpoint would block.
  Debug possibilities to force a sleep while the bitmap is over-allocated.
  In case of error in get_head_or_tail() in allocate_and_write_block_record(),
  we still need to unpin all pages.
  Bugfix: _ma_apply_redo_insert_row_blobs() produced wrong
  data_file_length.
storage/maria/ma_blockrec.h:
  new bitmap calls.
storage/maria/ma_checkpoint.c:
  filter_flush_indirect not needed anymore (flushing bitmap
  pages happens in _ma_bitmap_flush_all() now). So
  st_filter_param::is_data_file|pages_covered_by_bitmap not needed.
  Other filter_flush* don't need to flush bitmap anymore.
  Add debug possibility to flush all bitmap pages outside of a checkpoint,
  to simulate pagecache LRU eviction.
  When the background flush/checkpoint thread notices it has nothing
  to flush, it now sleeps directly until the next potential checkpoint
  moment instead of waking up every second.
  When in checkpoint we decide to not store a table in the checkpoint record
  (because it has logged no writes for example), we can also skip flushing
  this table.

  When we forget about an old transaction we must really forget
  about it with bzero() (fixes the "long_trid!=0 assertion" recovery
  bug). When we delete a row with maria_delete() we turn on
  STATE_NOT_OPTIMIZED_ROWS so we do the same when we see a CLR_END
  for an UNDO_ROW_INSERT or when we execute an UNDO_ROW_INSERT (in both
  cases a row was deleted). Pick up max_long_trid from the checkpoint record.

When we log UNDO_KEY_INSERT for an auto_inc key, we update
state.auto_increment (not anymore at the end of maria_write() except
if this is a non-transactional table). When Recovery sees UNDO_KEY_INSERT
in the REDO phase, it reads the auto_inc value from it and updates
state.auto_increment.


mysql-test/r/maria-recovery.result:
  Without the code fix, there would be in CHECK TABLE:
  "Auto-increment value: 0 is smaller than max used value: 3"
  and no AUTO_INCREMENT= clause in SHOW CREATE TABLE.

  Such hook needs a new member st_msg_write_hook_for_undo_key::auto_increment,

storage/maria/ma_loghandler.c:
  UNDO_KEY_INSERT gets a dedicated write_hook, to set auto_increment.
storage/maria/ma_recovery.c:
  When in the REDO phase we see UNDO_KEY_INSERT: if the state is older
  than this record, and the key is the auto_increment one, read
  the key's value from the log record and update state.auto_increment.
storage/maria/ma_test_all.sh:

storage/maria/ma_update.c:

  If table is transactional, state.auto_increment is already updated
  in write_hook_for_undo_key_insert().
storage/maria/ma_write.c:
  If table is transactional, state.auto_increment is not updated at
  the end of maria_write() but rather in write_hook_for_undo_key_insert()
  (under log's mutex, so that a concurrent checkpoint does not read
  state.auto_increment while it is changing - corrupted).
  _ma_ck_write_btree_with_log() extracts the auto_increment value
  from the key, puts it into msg.auto_increment, and this is passed
  to write_hook_for_undo_key_insert().
storage/maria/maria_def.h:

fix for bug: if a crash happened right after writing a REDO like this:
REDO - UNDO - REDO*, then recovery would ignore the last REDO* (ok),
rollback: REDO - UNDO - REDO* - REDO - CLR, and a next recovery would
thus execute REDO* instead of skipping it again. Recovery now logs
LOGREC_INCOMPLETE_GROUP when it meets REDO* for the first time,
to draw a boundary and ensure it is always skipped. Tested by hand.
Note: ma_test_all fails "maria_chk: error: Key 1 - Found too many records"
not due to this patch (failed before).

  upcoming UNDO phase can write more records for such transaction,
  a future recovery won't pair the incomplete group with the
  CLR_END (as there is LOGREC_INCOMPLETE_GROUP to draw a boundary).
