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.

Add 64bit statistic counters to the ng_ppp node.
64bit counters are needed to simplify traffic accounting and

Mechanically kill hard sentence breaks and double whitespaces.

Hiten's patchset for section four manpages, slightly edited by me.

mdoc(7) police: Use the new .In macro for #include statements.

Removed whitespace at end-of-line; no content changes. I simply did
cd src/share; find man[1-9] -type f|xargs perl -pi -e 's/[ \t]+$//'

BTW, what editors are the culprits? I'm using vim and it shows
me whitespace at EOL in troff files with a thick blue block...

mdoc(7) police: removed HISTORY info from the .Os call.

mdoc(7) police: remove extraneous .Pp before and/or after .Sh.

mdoc(7) police: in mdocNG, -offset and -width values without scaling
indicator are treated as strings, so "-offset 0" will set the offset
to the width of the string "0", as opposed to "no offset".

TIP: if offset is not needed, the -offset clause may be omitted.
