7bda966394 Add a dtrace provider for UDP-Lite.
The dtrace provider for UDP-Lite is modeled after the UDP provider.
This fixes the bug that UDP-Lite packets were triggering the UDP
provider.
Thanks to dteske@ for providing the dwatch module.

7575d3df5b The IP, TCP, and UDP provider report IP addresses as strings.
In some cases, the required information is not available and the
UDP provider reported an empty string in this case and the IP
and TCP provider reported a NULL pointer.

This patch changes the value provided in this case to the string
"<unknown>". This make the behaviour consistent and in-line with
the behaviour of Solaris.

4349a2145f Convert ipv4_flags and ipv4_offset fields into host byte order.
Also save only high bits in the ipv4_flags, because it is defined
as uint8_t. So now it will show DF and MF flags as 0x40 and 0x20.

c50c331896 Remove an unneeded typedef of ip6_t from the DTrace ip provider library.
It causes an error when ipfilter is enabled, since ipl.ko contains an
identical typedef.

7e518a6648 - Use an explicit "depends_on module kernel" guard in DTrace libraries that
reference types defined in the kernel. Otherwise dtrace(1) expects to find
  CTF definitions for all referenced types, which is not very reasonable
  when it is being used in a build environment. This was previously worked
  around by adding "-x nolibs" to dtrace -h or -G invocations, but as of
  r283025, dtrace(1) actually handles dependencies properly, so this is no
  longer necessary.
- Remove "pragma ident" directives from DTrace libraries, as they're being
  phased out upstream as well.

2f28ceeb34 Bind ip/tcp/udp provider translators and symbols to the same versions as in
illumos, rather than using "1.0" everywhere.

Some of the translators use D functions that are not present in version
1.0 (e.g. inet_ntoa()) which can result in libdtrace crashing when running
scripts that restrict themselves to version 1.0
(e.g. with "-x version=1.0").

57f6086735 Implement the ip, tcp, and udp DTrace providers. The probe definitions use
dynamic translation so that their arguments match the definitions for
these providers in Solaris and illumos. Thus, existing scripts for these
providers should work unmodified on FreeBSD.
