Analysis: For some reason actual thread handle is not
returned on Windows instead lpThreadId was returned and
thread handle was closed after thread create. Later
CloseHandle was called for recv_writer_thread_handle
and psort_info->thread_hdl.
Fix: Return thread handle from os_thread_create()
also on Windows and store these thread handles also
in srv0start.cc so that they can be later closed.
Analysis: When database is migrated from 5.5 or earlier and
database needs crash recovery, there is possibility that
SYS_DATAFILES system table does not exists, but
crash recovery in function dict_check_tablespaces_and_store_max_id()
assumes that SYS_DATAFILES exists.
Fix: If SYS_DATAFILES does not exists, create it before
we end up to function dict_check_tablespaces_and_store_max_id()
on crash recovery.
