Subject: [RFC] cleanup bcache bio handling v2

Hi all,

this series cleans up various places where bcache is way too intimate
with bio internals.  This is intended as a baseline for the multi-page
biovec work, which requires some nasty workarounds for the existing
code.

Note that I do not have a bcache test setup, so this will require
some careful actual testing with whatever test cases are used for
bcache.

Also the new bio_reused helper should be useful at least for MD raid,
but that work is left for later.

Changes since v1:
 - restore bi_size properly
