Preliminary test case updates
Add rule for test beam'es
Test case cleanup
Minor test case rework
Calculation of term_spec size (initial and next) changed

There seem to be some problem with realloc (core dump)
so the calculation of the term_spec size needs to be
"corrected".
Add new messages
Uncommented test cases
Ensure of incorrect number of terms when scanning property groups

At the end of the mfs_load_property_groups function, the
final property group list and property groups list is
"terminated". A call to mfs_ensure_term_spec with (incorrect)
size 4 was made prior to this to ensure enough data was available.
The correct size was 6!
Repeat flush loop at timeout intervals
erts: Refactor in new struct ErtsAllctrFixDDBlock_t

to replace macro constant ERTS_ALCU_DD_FIX_TYPE_OFFS.
erts: Fix benign size-bug for fix-allocators MONITOR_SH and NLINK_SH

Bug will (as it seems) only result in faulty statistics.
erts: Fix unabused bug in fixed allocation

Make sure each fix allocator type always allocate the right fixed size.
Removed comments
Merge branch 'bmk/megaco/flex_scanner_core/seq12263' into bmk/megaco/flex_buffer_overrun_while_scanning_prop_parms/OTP-10998/r13

Conflicts:
	lib/megaco/src/flex/megaco_flex_scanner_drv.flex.src
Assign correct version and updated release notes accordingly.

Also added (and cleaned up) appup.
Changed name of test case functions (from seq12263 to otp10998)
mnesia: Fixed bad data in table

If mnesia:cleartable/1 was called during a table_load an schema event
with delete and write of that table is sent, which caused the table
to contain the schema record instead of clearing the table.
erts: Adjust sizes for fix allocator
erts: Change locking order for "port_table" and "port_sched_lock"

Keep order between the two but move them before all the allocation locks.

Old order violated for "port_table" lock in ptab_list_bif_engine().
fix srp_anon ciphers suites requiring certificates to work.

This problem was not caught by the test suites since all PSK and SRP
suites where always tested with certificates. Split those tests into
test with and without certificates.
