Add a -i option to sed(1) to do inplace editing, to give us an alternative to
Perl for such things.  The key difference to Perl is that a backup extension
*MUST* be specified, because on one hand it isn't recommended to have options
which optionally take a parameter, and on the other hand, it'd be slightly
unpleasent to implement proper handling for that.

The difference between this and the version posted to developers@ is that it
does handle multiple files in argv after the getopt(3) handling "correctly",
in that the inplace editing-specific code has been moved out to a function,
and that function is used beyond the first file in our linked list.

This option has been documented as FreeBSD-specific in the manpage.
