We don't have to keep a helper function just for the sake of a PBUF_RAW
constant. Inline ppp_singlebuf function.

pbuf_coalesce() creates a single pbuf out of a chain of pbufs, which is
exactly what ppp_singlebuf() need.

Current code fails to allocate zero length pbuf (e.g. for PBUF_RAW PBUF_POOL),
fix it.
Fixes: eb269e61b5d3 ("First step to clean up pbuf implementation: add pbuf_alloc_reference() to allocate pbufs referencing external payload; move member initialization to common function; simplify PBUF_POOL chain allocator")

This changes the CMSG alignment macros to ensure struct cmsghdr and data
are on a word (double word on 16-bit arch) aligned boundary
We need to ensure at least 32-bit alignment for 16-bit systems because
socklen_t could be 32-bit due to our definition
