* ssh: Fixed port leakage if a ssh:daemon call failed.

* erts: Fixed bug on big endian architectures when changing
file permissions or ownership with file:change_mode,
change_owner, change_group or write_file_info. Bug
exists since OTP-21.0.
* erts: Fixed bug in operator band of two negative operands
causing erroneous result if the absolute value of one
of the operands have the lowest N*W bits as zero and
the other absolute value is not larger than N*W bits. N
is an integer of 1 or larger and W is 32 or 64
depending on word size.
* ssl: Fixed renegotiation bug. Client did not handle server
initiated renegotiation correctly after rewrite to two
connection processes, due to ERL-622 commit
d87ac1c55188f5ba5cdf72384125d94d42118c18. This could
manifest it self as a " bad_record_mac" alert.
Also included are some optimizations

* HIGHLIGHTS
* erts, sasl: New counters and atomics modules supplies access to
highly efficient operations on mutable fixed word sized
variables.
* erts: There is a new module persistent_term that implements a
term storage suitable for terms that are frequently
used but never or infrequently updated. Lookups are
done in constant time without copying the terms.
* ssh: Requires OpenSSL 1.1.1 or higher as cryptolib under the
OTP application crypto.
* ssl: *** POTENTIAL INCOMPATIBILITY ***
ssl now uses active n internally to boost performance.
Old active once behavior can be restored by setting
application variable see manual page for ssl
application (man 6).
* erts: Add a new pollset that is made to handle sockets that
use {active, true} or {active, N}. The new pollset will
not be polled by a pollthread, but instead polled by a
normal scheduler.
This change was made because of the overhead associated
with constantly having to re-apply the ONESHOT
mechanism on fds that all input events were
interesting.
The new pollset is only active on platforms that
support concurrent kernel poll updates, i.e. Linux and
BSD.
* POTENTIAL INCOMPATIBILITIES:
kernel: A new function, logger:update_handler_config/3 is
added, and the handler callback changing_config now has
a new argument, SetOrUpdate, which indicates if the
configuration change comes from set_handler_config/2,3
or update_handler_config/2,3.
This allows the handler to consistently merge the new
configuration with the old (if the change comes from
update_handler_config/2,3) or with the default (if the
change comes from set_handler_config/2,3).
The built-in handlers logger_std_h and
logger_disk_log_h are updated accordingly. A bug which
could cause inconsistency between the handlers'
internal state and the stored configuration is also
corrected.
* ssl: ssl now uses active n internally to boost performance.
Old active once behavior can be restored by setting
application variable see manual page for ssl
application (man 6).
