This change adds a function valid_opt() which does the following
things:
1. Checks if the returned optchar is among the list of optstring
supported by the command.
2. Checks if the returned optchar is a valid non-ASCII
option. Currently, we do not maintain a list of non-ASCII options
supported by each command. So, this function returns true if the
optchar returned by getopt_long falls within the allowed range.

Currently cbfstool cherry-picks a few files from vboot and hopes these
files will work standalone without any dependencies. This is pretty
brittle (for example, CL:2084062 will break it), and could be improved
by building the whole vboot library and then linking against it.
Therefore, this patch creates a new target $(VBOOT_HOSTLIB) and includes
it as a dependency for cbfstool and ifittool.
To prevent building the vboot lib twice (one for cbfstool and the other
for futility) when building coreboot tools together, add the variable
'VBOOT_BUILD' in Makefile to define a shared build path among different
tools so that vboot files don't need to be recompiled.
Also ignore *.o.d and *.a for vboot library.

In glibc feature control macros, _DEFAULT_SOURCE is the shorthand to
tell glibc to enable "all the default stuff", meaning POSIX, BSD and
System V interfaces. However, this macro is somewhat recent and older
glibc versions (e.g. 2.12) are still occasionally in use that don't
recognize it yet. For the benefits of users with these versions, let's
also enable the deprecated _BSD_SOURCE and _SVID_SOURCE macros which
essentially achieve the same thing. We must continue to define
_DEFAULT_SOURCE so that newer glibc versions don't throw a deprecation
warning.
This patch should make BSD-style byteswap macros like le32toh()
available on these older glibc versions.

This patch creates a new commonlib/bsd subdirectory with a similar
purpose to the existing commonlib, with the difference that all files
under this subdirectory shall be licensed under the BSD-3-Clause license
(or compatible permissive license). The goal is to allow more code to be
shared with libpayload in the future.
Initially, I'm going to move a few files there that have already been
BSD-licensed in the existing commonlib. I am also exracting most
contents of the often-needed <commonlib/helpers.h> as long as they have
either been written by me (and are hereby relicensed) or have an
existing equivalent in BSD-licensed libpayload code. I am also
relicensing <commonlib/compression.h> (written by me) and
<commonlib/compiler.h> (same stuff exists in libpayload).
Finally, I am extracting the cb_err error code definitions from
<types.h> into a new BSD-licensed header so that future commonlib/bsd
code can build upon a common set of error values. I am making the
assumption here that the enum constants and the half-sentence fragments
of documentation next to them by themselves do not meet the threshold of
copyrightability.

This patch adds an optional pre-RAM cache for the FMAP which most
platforms should be able to use, complementing the recently added
post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP
about half a dozen times from flash in verstage, which will all be
coalesced into a single read with this patch. It will also help
future vboot improvements since when FMAP reads become "free" vboot
doesn't need to keep track of so much information separately.
In order to make sure we have a single, well-defined point where the new
cache is first initialized, eliminate the build-time hardcoding of the
CBFS section offsets, so that all CBFS accesses explicitly read the
FMAP.
Add FMAP_CACHEs to all platforms that can afford it (other than the
RISC-V things where I have no idea how they work), trying to take the
space from things that look like they were oversized anyway (pre-RAM
consoles and CBFS caches).

Considering the following integer multiplication:
u64 = u16 * u16
What on earth, one might wonder, is the problem with this? Well, due to
C's unfortunately abstruse integer semantics, both u16's are implicitly
converted to int before the multiplication, which cannot hold
all possible values of a u16 * u16. Even worse, after overflow the
intermediate result will be a negative number, which during the
conversion to a u64 will be sign-extended to a huge integer. Not good.
The solution is to manually cast one of the u16 to a u32 or u64, which
are large enough to not have any overflow and will prevent the implicit
conversion. The type of the u64 is preferred, though a u32 is used
instead of size_t, since that can change depending on the platform.

The Flashmap (FMAP) was not clearly documented. The new flashmap.md
explains where to find more details about that and how / why it was used
in coreboot. Also explained what is FMD and how to use it (based on
original README.fmaptool).

When updating firmware, it is very often that we may want to preserve
few sections, for example vital product data (VPD) including serial
number, calibration data and cache. A firmware updater has to hard-code
the section names that need to be preserved and is hard to maintain.
A better approach is to specify that in FMAP area flags (the `area_flag`
field) using FMAP_AREA_PRESERVE. With this patchset, a FMD parser flag
"PRESERVE" is introduced and will be converted to FMAP_AREA_PRESERVE
when generating FMAP data (by fmap_from_fmd.c).
For example, The FMD statement:
RO_VPD(PRESERVE)@0x0 16k
will generate an FMAP firmware section that:
area_name = "RO_VPD"
area_offset = 0
area_size = 16384
area_flags = FMAP_AREA_PRESERVE

Manually added 'PRESERVE' to some FMD files, and verify (by running
fmap.py) the output coreboot.rom has FMAP_AREA_PRESERVE set

The idea of "annotation" for firmware sections was pretty flexible, but
in future we will want multiple attributes applied to same area. For
example, indicate the section must be preserved when updating firmware
so serial number or MAC address can be preserved.
The solution here is to extend annotation so it can take multiple
identifiers (flags) in a row. For example, to declare a 64KB COREBOOT
section as CBFS using annotation:
COREBOOT(CBFS)@0x0 64k
If there's a new flag "PRESERVE" indicating the section must be
preserved before update, we can declare it following CBFS flag:
COREBOOT(CBFS PRESERVE)@0x0 64k
The flags are directly parsed in fmd_parser, and stored in an union
flashmap_flags. Output modules can choose to ignore or process the
flags.
Currently the only supported flag is "CBFS" (for backward compatible
with annotation). There will be more new flags in follow up patches.

When updating firmware, we may need to preserve some sections like VPD,
calibration data, ... etc. The logic can be hard-coded in updater as a
list of known names, but a better solution is to have that directly
declared inside FMAP area flags.
To do that, the first step is to apply the changes in flash map
(http://crosreview.com/1493767). A new FMAP_AREA_PRESERVE is now
defined and will be set in future with new syntax in FMD parser.

Put the FMAP FMAP region right above the coreboot CBFS region.
The other regions like RW_MRC_CACHE and CONSOLE often have alignment
requirements so it makes sense to put those on top. This also
simplifies the code the generate the default fmap a little.

There is already a function with the name buffer_size(). Adding a local
variable with the same name will lead to the following error on older
GCC versions (e.g. version 4.4.7):
declaration of 'buffer_size' shadows a global declaration
To fix this rename the local variable to buffer_len.
