MDEV-12600: crash during install_db with innodb_page_size=32K and ibdata1=3M;bb-10.1-MDEV-12113

Problem was that all doublewrite buffer pages must fit to first
system datafile.

    BUG#21551464 - SEGFAULT WHILE INITIALIZING DATABASE WHEN
    INNODB_DATA_FILE SIZE IS SMALL

To 10.1 (with extended error printout).

btr_create(): If ibuf header page allocation fails report error and
return FIL_NULL. Similarly if root page allocation fails return a error.

dict_build_table_def_step: If fsp_header_init fails return
error code.

fsp_header_init: returns true if header initialization succeeds
and false if not.

fseg_create_general: report error if segment or page allocation fails.

innobase_init: If first datafile is smaller than 3M and could not
contain all doublewrite buffer pages report error and fail to
initialize InnoDB plugin.

row_truncate_table_for_mysql: report error if fsp header init
fails.

srv_init_abort: New function to report database initialization errors.

srv_undo_tablespaces_init, innobase_start_or_create_for_mysql: If
database initialization fails report error and abort.

trx_rseg_create: If segment header creation fails return.
