Globally replace u_int*_t from (non-contributed) man pages.

The reasoning behind this, is that if we are consistent in our
documentation about the uint*_t stuff, people will be less tempted to
write new code that uses the non-standard types.

I am not going to bump the man page dates, as these changes can be
considered style nits. The meaning of the man pages is unaffected.

Now that lnc(4) is removed from the source tree, replace lnc0 in an example
with fxp0 (fxp(4) was chosen as it's also used in a couple of examples in
other man pages and as it has good grep(1)'ability).

Verify that SYNOPSIS section compiles.

(fast) ethernet -> (Fast) Ethernet

Replace all uses of the old netgraph constants NG_*LEN by the new
constants NG_*SIZ that include the trailing NUL byte. This change
is mostly mechanical except for the replacement of a couple of snprintf()
and sprintf() calls with strlcpy.

Slight correction to ng_etf man page and add it to the list
of man pages to install.

mdoc(7) police: cleanup.

Fix typos.

A node that allows ethernet type packets to be filtered to different
hooks depending on ethertype. Great for prototyping protocols.
connects to the lower and upper hooks of an ethernet type of node.
