Fixed bugs found by pushbuild

Added code to detect and give error when doing an insert into a view where we accessed fields in a not yet read table
Disabled test in subselect.test as the CHECK_OPTION for views doesn't work for insert.
This needs to be fixed properly later.

The problem with views are described in Bug #41760 Inserting into multiple-table views is not working

mysql-test/r/insert.result:
  Fixed wrong usage of insert into view.
mysql-test/r/subselect.result:
  Disabled wrong test (temporary)
mysql-test/suite/maria/r/maria.result:
  Added test of size of table
mysql-test/suite/maria/t/maria.test:
  Added test of size of table
mysql-test/t/insert.test:
  Fixed wrong usage of insert into view
  The bug is that during insert/update we currently don't read any of the referenced tables of the view.
  This means that we can't get a value from another table to use as part of the update.
mysql-test/t/subselect.test:
  Disabled not working test until someone has time to fix insert into view properly
  Here we where refering to last used value in t2, which is wrong.
sql/sql_insert.cc:
  Detect if we are trying to update one table in a view based on value in another, not yet read, table.
  This fixes the problem discovered in insert.test
storage/maria/ma_blockrec.c:
  Don't ignore not critical changes to the last page in the table.
  We need to write the last page as otherwise we can during aborting of a row with a duplicate key get
  state.data_file_length and the real length of file out of sync
storage/maria/ma_check.c:
  Flush the page cache even if we got an error during zerofill.
  (This fixes a call to assert() in case of a too short data file)
storage/maria/ma_pagecache.c:
  Mark page as read when we do a write of a full page.
  This fixes a bug when we got an error during read and then used direct write to page to update it
storage/maria/ma_state.c:
  Restore info->lock.type after call to maria_versioning.
  Fixed crash in maria_recover.test
storage/maria/maria_read_log.c:
  Don't write thread id in debug log. (Not needed as maria_read_log is a single treaded program)
