enable pcap_debug

Don't build with OpenSSL by default because we install in /lib and there
is no libcrypto there.

merge conflicts between libpcap 1.9.1 and 1.10.4

adapt to ${CC_WNO_IMPLICIT_FALLTHROUGH}

Use ${CC_WNO_IMPLICIT_FALLTHROUGH} instead of
the older style more complex expressions.

bsd.own.mk: rename GCC_NO_* to CC_WNO_*

Rename compiler-warning-disable variables from
	GCC_NO_warning
to
	CC_WNO_warning
where warning is the full warning name as used by the compiler.

GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

Mostly merge changes from HEAD upto 20200411

rpcap://<host>/interface support.

need bsd.init.mk to grab Makefile.inc

ENABLE_REMOTE and add rpcapd(8)

introduce some common variables for use in GCC warning disables:

GCC_NO_FORMAT_TRUNCATION    -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION  -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW    -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE   -Wno-cast-function-type (GCC 8)

use these to turn off warnings for most GCC-8 complaints.  many
of these are false positives, most of the real bugs are already
commited, or are yet to come.


we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."

merge conflicts

convert HAVE_GCC == 7 to HAVE_GCC >= 7.

Sync with HEAD

ignore a format truncation issue.

- use -Wno-error=implicit-fallthrough with GCC7.

Sync with HEAD

Resolve a couple of conflicts (result of the uimin/uimax changes)

search first for the kernel bpf_filter.c

Yet another pcap include.

fix includes

pcap/export-defs.h no longer exists, so don't attempt to install it.

Allows builds after libpcap update to get further, if there is fallout
from the file being missing elsewhere, that can be fixed later.

make 'clean' and/or 'cleandir' actually clean all the things.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

resync from head

add the rest of the man pages.

install in /lib per rmind's request

new libpcap

sync with head

Don't use libpcap's bpf file, but use our own:
1. include <net/dlt.h> where needed since we have the information in a separate
   file.
2. #error in pcap/bpf.h to make sure it is not being used.
3. If we don't include <pcap/bpf.h> include <net/bpf.h> instead.
4. Install symlinks instead of copies of files.

max WARNS is 4

revert v1.31 (when this was lib/libpcap/Makefile), the HAVE_PCC
is not any longer required since pcc understands gcc attributes
now

avoid/document non-literal format strings

Remove spurious trailing slash; PR 45067 from Henning Petersen.

Default to -Wno-sign-compare -Wno-pointer-sign for clang.
Push -Wno-array-bounds down to the cases that depend on it.
Selectively disable warnings for 3rd party software or non-trivial
issues to be reviewed later to get clang -Werror to build most of the
tree.

we need some more files here.

- add our fixes
- make compile with WARNS=5
- add glue
