Fix syslog defines

config.h defines HAVE_SYSLOG_H whereas the sources are looking for
NO_SYSLOG to be undefined. As the logic of "if feature is available"
makes more sense than "if feature is not unavailable", I opted for the
config.h define.
Define LOG_ERR for systems without syslog.h

erts: Add the +sfwi system flag

+sfwi Interval
    Set scheduler forced wakeup interval. All run queues will be scanned
    each Interval milliseconds. While there are sleeping schedulers in
    the system, one scheduler will be woken for each non-empty run queue
    found. An Interval of zero disables this feature, which also is the
    default.

    This feature has been introduced as a temporary workaround for lengthy
    executing native code, and native code that do not bump reductions
    properly in OTP. When these bugs have be fixed the +sfwi flag will
    be removed.

asn1_SUITE: Remove useless test_driver_load/1 test case

The PER back-end no longer use a driver (or even a NIF),
and the test case would not fail if it didn't work because the
spawned processed were not linked.
asn1_SUITE: Remove unused function case_dir/2
asn_SUITE: Fold per_GeneralString/1 into h323test

The per_GeneralString/1 test case compiles MULTIMEDIA-SYSTEM-CONTROL
and then does a single decoding. Save some compilation time by folding
the test into the h323test/1 test case.
