[MINOR] add the splice_len member to the buffer struct in preparation of splice support

In preparation of splice support, let's add the splice_len member
to the buffer struct. An earlier implementation made it conditional,
which made the whole logics very complex due to a large number of
ifdefs.

Now BF_EMPTY is only set once both buf->l and buf->splice_len are
null. Splice_len is initialized to zero during buffer creation and
is currently not changed, so the whole logics remains unaffected.

When splice gets merged, splice_len will reflect the number of bytes
in flight out of the buffer but not yet sent, typically in a pipe for
the Linux case.
