MDEV-17124: mariadb 10.1.34, views and prepared statements: ERROR 1615 (HY000): Prepared statement needs to be re-preparedbb-10.1-MDEV-17124

The problem is that if table definition cache (TDC) is full of real tables which are in tables cache, view definition can not stay there so will me removed by its own underlying tables.
In situation above old mechanism of detection matching definition in PS and current version always require reprepare and so prevent executing the PS.
One work arount is to increase TDC, other - improve version check for views (which is done here).
Now in suspiciouse cases we check MD5 of the view to be sure that version really have chenged.
