Several small improvements of the stack checking code:
- move the CPU0 stack check right before jumping to the payload
and out of hardwaremain (that file is too crowded anyways)
- fix prototype in lib.h
- print size of used stack
- use checkstack function both on CPU0 and CPU1-x
- print amount of stack used per core

In hardwaremain() we can't add timestamps before we actually
reinitialized the cbmem area. Hence we kept the timestamps in
an array and added them later. This is ugly and intrusive and
helped hiding a bug that prevented any timestamps to be logged
in hardwaremain() when coming out of an S3 resume.
The problem is solved by moving the logic to keep a few timestamps
around into the timestamp code. This also gets rid of a lot of ugly
ifdefs in hardwaremain.c

Previous patches implemented stack overflow checking for the APs.
This patch builds on the BSP stack poisoning patch to implement
stack overflow checking for the BSP, and also prints out maximum
stack usage. It reveals that our 32K stack is ridiculously oversized,
especially now that the lzma decoder doesn't use a giant 16K on-stack
array.
Break the stack checking out into a separate function, which
we will later use for the APs.
CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8
To test failure, change the DEADBEEF stack poison value in c_start.S
to something else. Then we should get an error like this:
Stack overrun on BSP.Increase stack from current 32768 bytes
CPU0: stack from 00180000 to 00188000:Lowest stack address 00180000
Separate the act of loading from the act of starting the payload. This
allows us better error management and reporting of stack use. Now we
see:
CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8

3 (with one of them way too much assembler code).
On the way, I had to make some changes to the way the code is built,
which is an effort I want to expand over time.
Right now, large portions of the in-ROM part of coreboot is compiled as
a single file, with lots of .c files including other .c files.
That has its justification for pre-raminit code, but it also affects
lots of post-raminit code (memcpy doesn't really make sense before
raminit, or at least CAR)
The coreboot_apc code (AMD boards) gained some .c includes because I
don't know that part of the code enough to really rework it and only
have limited possibilities to test it. The includes should give an
identical situation for this part of the code.
This change was posted as set of 6 patches to the list, but they
were mostly split for review purposes, hence commit them all at once.
They can still be backed up using the patch files, if necessary.

romfs.
Everything else to make a target romfs aware happens in the targets.
What the patch does:
1. missing romfs.h include
2. special handling while creating coreboot.rom
While the romfs code path in the makefile doesn't actually use the file,
it's possible that the build of coreboot.rom fails in a romfs setup,
because the individual buildrom image is too small to host both coreboot
and payloads (as the payloads aren't supposed to be there). Thus, a
special case to replace the payload with /dev/null in case of a romfs
build.
There would be cleaner ways, but they're not easily encoded in the
Config.lb format.
3. config.g is changed to create rules for a romfs build
Targets should still build (they do for me)
