Merge 10.1 into 10.2

Disable the test encryption.innodb_encryption-page-compression
because the wait_condition would seem to time out deterministically.
MDEV-14814 has to be addressed in 10.2 separately.

Datafile::validate_first_page(): Do not invoke
page_size_t::page_size_t(flags) before validating the tablespace flags.
This avoids a crash in MDEV-15333 innodb.restart test case.
FIXME: Reduce the number of error messages. The first one is enough.
