tedu bpf_mtap_pflog().
now that it is a trivial wrapper around the extended bpf_mtap_hdr, we can
use bpf_mtap_hdr directly. added benefit: pflog_bpfcopy doesn't need to
be exported any more and can stay private to if_pflog.c

Make use of this wonderful modern C construct known as a `switch', instead of
8-line if() tests.
remove unused, private version strings except SSL_version_str

Also remove unused des_ver.h, which exports some of these strings, but is not installed.

cast ASN1_STRING (unsigned char *) to match strlcat's argument (char *)

Resync _dl_opendir() with libc: use O_CLOEXEC and O_DIRECTORY instead
of post-open tests and fixups.  Also, reorder _dl_dirdesc to save
8 bytes on LP64.

Enable specifying the filesystem of interest by the duid.

Original diff from halex@ a while ago.

now that mclgeti doesnt do the rx ring accounting, cluster allocation
doesnt need to know which ifp an mbuf was allocated on so it can uncount
it on free.

while here, remove the ext_backend field which identifies the pool the
cluster came from and use ext_arg instead.

tedu the SSL export cipher handling - since we do not have enabled export
ciphers we no longer need the flags or code to support it.

ok beck@ miod@
delete forgotten, obsolete rew_warn() prototype
