In a yaboot conf file, we may see a device= directive that actually
specifies a partition (eg, sda1) rather than the underlying block device
(sda). If we then encounter a partition= directive, we don't handle the

lib/process: Add process helpers
We've grown-out of pb_run_cmd a little, as we have a number of different
process types:
boot():
- kexec: short-running process, run synchronously
- boot hooks: short-running, run sync, need exit code & stdout
network init:
- interface configuration: short running, run sync
- udhcp processes are long running, we may want completion, but
doesn't block other actions
downloads:
- potentially long-running, block parse progress
config nvram:
- read: short running, can block, need stdout
- write: short running, can block
We'd like to introduce proper asynchronous processes, to allow config &
boot-option downloads without blocking the discover server.
This change introduces a new type for processes, 'struct process'. These
structures are created with process_create, and run with
process_run_sync or process_run_async. The latter reports completion
through a callback member of struct process.

lib/waiter: Ensure waiters are consistent during waiter_poll
We have a bug at the moment: if the waitset's->waiters array is updated
duing waiter_poll() (eg, a client connection is closed, and the client's
callback performs a waiter_remove()), then we may invoke callbacks for
incorrect waiters.
This change uses a consistent waiters array duing execution of
waiter_poll, so that any pollfds returned from poll() will result in
correct callback invocations.
This assumes that a waiter will only ever remove *itself* from the
waitset; otherwise, we may call a free()ed waiter.
