Introduce a macro retry(attempts, condition, expr) for retrying a
condition, which is extensively used in coreboot.
Example usage:
if (!retry(3, read32(REG) == 0, mdelay(1))
printk(BIOS_ERR, "Error waiting for REG to be 0\n");

We had the addrspace_32bit rdev in prog_loaders.c for a while to help
represent memory ranges as an rdev, and we've found it useful for a
couple of things that have nothing to do with program loading. This
patch moves the concept straight into commonlib/region.c so it is no
longer anchored in such a weird place, and easier to use in unit tests.
Also expand the concept to the whole address space (there's no real need
to restrict it to 32 bits in 64-bit environments) and introduce an
rdev_chain_mem() helper function to make it a bit easier to use. Replace
some direct uses of struct mem_region_device with this new API where it
seems to make sense.

The current test framework builds the test code without any warnings at
all, which isn't great -- we have already slipped in some cases of
non-void functions not returning a defined value, for example. It would
likely be overkill to try to use all the same warnings we use for normal
coreboot code (e.g. some stuff like -Wmissing-prototypes makes cmocka's
__wrap_xxx() mock functions unnecessarily cumbersome to work with, and
other things like -Wvla may be appropriate for firmware but is probably
too aggressive for some simple test code). Therefore, let's just add
some of the stuff that points out the most obvious errors.

This patch adds a basic test for the common region and region_device
APIs, sanity checking the basic functions and things like
overflow-handling. There is certainly more that could be added here, but
it's a start.
