====================
ucc_geth improvements

This is a resend of some improvements to the ucc_geth driver that was
previously sent together with bug fixes, which have by now been
applied.

v2: rebase to net/master; address minor style issues; don't introduce
a use-after-free in patch "don't statically allocate eight
ucc_geth_info".
