Fix the other typo, so setting CPPFLAGS in the environment works correctly.

Discuss buffering when describing the -w flag.

Mention that the output of tcpdump -w is buffered, and note that this
means packets won't necessarily show up in the output as soon as they're
received, so programs reading that output won't see them immediately,
and note that the -U flag forces "packet buffering" so that a reader
will see the packets as soon as they're received.
Give more information on -l, and note that -U works without -w.

Note that -l, on Windows (i.e., in WinDump), is unbuffered, not
line-buffered, and describe -U as an alternative (that doesn't have that
problem on Windows).

Note that -U does packet-buffering without -w.

Fix up the formatting of the example command lines with -l.

add DNSSL (RFC6106) support

The most notable difference between RFC5006 and RFC6106 is the addition
of DNSSL RA option. This commit adds DNSSL handling code to make tcpdump
fully RFC6106-aware. This code has been tested against RA packets
generated by Quagga and radvd.
