Add a method of running pre-boot hooks. Executable files in
/etc/petitboot/boot.d/ are run (in order) before we start the boot
process.

Add a library for (name, value) configuration.
Different storage backends are allowed (although currently hardcoded to
powerpc nvram), and config is read-only at present.

change is in follow up to inverting the order that the server

so do the getch() once in cui_process_key, and pass the result to the
callback.

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.

Since we reallocate set->waiters, we can't hand out pointers to within
that array.
Instead, this change allocates the 'struct waiter's separately from the
set->waiters array.

When a client disconnects, the read from the client's fd will return
EOF. We should destroy the client in this situation.

We should talloc_free the parser list once we're done, enabling
valgrind's leak check. Before:
[jk@pablo parser]$ valgrind ./test-null
...
==9330== HEAP SUMMARY:
==9330== in use at exit: 288 bytes in 3 blocks
==9330== total heap usage: 11 allocs, 8 frees, 1,177 bytes allocated
After:
[jk@pablo parser]$ valgrind ./test-null
...
==9940== HEAP SUMMARY:
==9940== in use at exit: 0 bytes in 0 blocks
==9940== total heap usage: 11 allocs, 11 frees, 1,177 bytes allocated
==9940==
==9940== All heap blocks were freed -- no leaks are possible

Add a new routine check_not_present_resource() to check
that a resource is not present. This is typically used
to check that an initrd entry has not been found.
Also add any needed checks for no initrd to the existing
tests.
