Match the end-of-line after file extensions, so that *.[ch] files
with version numbers in their pathnames (e.g., libpcap-0.8.3/gencode.c)
do not match the manual-page regular expression.
size (via BIOCSBLEN). Obtained from FreeBSD 4.x; originally from
http://www.tcpdump.org's version of libpcap.
Taken verbatim from the FreeBSD 4.9 version, lint and all, other than
increasing the maximum size from 32Kibyte to an extremely generous
4Mibytes. We assume root will configure the in-kernel maximum value
sensibly on small-memory machines.
* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.
* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx
* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES
* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}
* Deprecate the (short lived) DEPENDSRCS
Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.
Tested with "make -j 8 distribution" and "make distribution".
* When opening a live pcap, obtain the list of supported DLTs from
the BPF.
* Add pcap_list_datalinks() to obtain a list of supported DLTs
supported by the interface associated with the pcap descriptor.
* Add pcap_set_datalink() to set the current DLT of the pcap.
* Bump shlib 1.2 -> 1.3; new functions added.

- icmptype (offset of ICMP type field)
- icmpcode (offset of ICMP code field)
- tcpflags (offset of TCP flags field)
and field values:
- icmp-echoreply, icmp-unreach, icmp-sourcequench,
icmp-redirect, icmp-echo, icmp-routeradvert,
icmp-routersolicit, icmp-timxceed, icmp-paramprob,
icmp-tstamp, icmp-tstampreply, icmp-ireq, icmp-ireqreply,
icmp-maskreq, icmp-maskreply
- tcp-fin, tcp-syn, tcp-rst, tcp-push, tcp-ack, tcp-urg
This allows expressions like the following:
icmp[0] = 3
(tcp[13] & 0x02) != 0
to be written as:
icmp[icmptype] = icmp-unreach
(tcp[tcpflags] & tcp-syn) != 0
which is a bit more user-friendly for e.g. writing packet filter rules.

Fix a hairy optimizer bug that causes the expression:
'ip and ((icmp and dst host 1.1.1.1 and not host 2.2.2.2) or (host 1.1.1.1 and src host 3.3.3.3))'
to compile incorrectly. Details about to be mailed to LBL.
from tcpdump.org, although with a slightly different signature.
The tcpdump.org version has no way to report an error string back
to the caller. This version takes an additional "errbuf" argument
(similar to pcap_open_*()).
