I tried to take into account all that have been discussed, but I have
to admit that I'm absolutely not sure of what was actually decided
here.  I went with those changes:

- rename wal_num_fpw to wal_fpw for consistency, both in pgss view
fiel name but also everywhere in the code
- change comments to consistently mention "full page writes generated"
- changed pgss and explain documentation to mention "full page images
generated", from Justin's patch on another thread
- kept "amount" of WAL bytes
- no change to the explain output as I have no idea what is the
consensus (one or two spaces, use semicolon or equal, show unit or
not)
