amd64 sendsig(): explicitly copy registers from trapframe to ucontext
With the IDT event delivery, previously reserved fields in tf_cs and
tf_ss are guaranteed to be zero. With FRED, these fields are not zero,
which affects the values copied to userspace.

syslogd: Fix ereregex property filters and add test
This change fixes Bug 293879, where ereregex filters in syslogd
did not handle alternation correctly.
The issue appears to come from mixing up two different kinds of
flags: syslogd's internal serialized filter flags in
usr.sbin/syslogd/syslogd.h, and the regex compilation flags from
include/regex.h. ereregex was storing REG_EXTENDED in cmp_flags,
even though cmp_flags is meant to carry syslogd's own FILT_FLAG_*
values for configuration serialization and reconstruction.
REG_EXTENDED has the same bit value as FILT_FLAG_EXCLUDE, so the
filter could be reconstructed with the wrong semantics.
The fix stores FILT_FLAG_EXTENDED instead, allowing syslogd to
correctly REG_EXTENDED when compiling the regex.
A test was also added for both ereregex and !ereregex filters.
