Integrate head.S directly into libc and remove all instances of head.o.
* Drop 'separate class' entry for head.S.
* Drop special treament for head.o inside lpgcc.
* Change the .text in `x86/head.S` to `.section .text._entry`.
* Drop arch/mock/head.c, initially added as a dummy file.

This moves the multiboot header into its own include file, simplifying
head.S and making it easier to include/exclude the multiboot header
based on config options.

When CONFIG_LP_MULTIBOOT is enabled, save the values of EAX and EBX
passed from the bootloader. This information can be useful for
multiboot payloads feature alone.

We should make sure _stack/_estack and the other labels are consistent.
And _data & _edata is also useful to clean up the sensitive data on the
data section.

The payload API of coreboot described in
https://www.coreboot.org/Payload_API does not reflect the current
handoff mechanism to hand the coreboot tables off. Therefore the
arguments supplied by coreboot (cbtable) will currently never be parsed
correctly and libpayload has to search for the coreboot tables by
iterating through memory.
This patch removes the old payload API implementation and just takes the
coreboot table pointer from the first argument on the stack.
Tested: started prodrive/atlas with coreinfo payload

Stefan thinks they don't add value.
Command used:
sed -i -e '/file is part of /d' $(git grep "file is part of " |egrep ":( */\*.*\*/\$|#|;#|-- | *\* )" | cut -d: -f1 |grep -v crossgcc |grep -v gcov | grep -v /elf.h |grep -v nvramtool)
The exceptions are for:
- crossgcc (patch file)
- gcov (imported from gcc)
- elf.h (imported from GNU's libc)
- nvramtool (more complicated header)

The coreboot sites support HTTPS, and requests over HTTP with SSL are
also redirected. So use the more secure URLs, which also saves a
request most of the times, as nothing needs to be redirected.
Run the command below to replace all occurences.
```
$ git grep -l -E 'http://(www.|review.|)coreboot.org'
| xargs sed -i 's,http://\(.*\)coreboot.org,https://\1coreboot.org,g'

Allows to use SSE and floating point in payloads without digging to
much into x86 assembly code.
Tested on Lenovo T500 (Intel Core2Duo).
Both floating point operation and SSE is properly working.

Implement the argc/argv passing as described in coreboot’s payload API:

While at it, give the code some love by not needlessly trashing register
values.

3 out of 4 architectures currently zero out the payload BSS in early
assembly code, which is pointless since the code loading the payload has
already done that (with a more efficient memset). ARM64 has never had
any code like this and can run just fine without it. This also defeats
the new optimization of moving the heap out of the BSS, since all three
implementations assume that everything between _edata and _end is BSS.
We should just take this out.
