Add the IntelFirmwareInterfaceTable-tool to modify the FIT.
As cbfstool is overloaded with arguments, introduce a new tool
to only modify FIT, which brings it's own command line syntax.
Provide clean interface to:
* Clear FIT
* Add entry to CBFS file
* Add entry to REGION
* Delete entries
* Add support for types other than 1
* Add support to dump current table
* Add support for top-swap
* Sort entries by type
Most code is reused from existing cbfstool and functionality of cbfstool
is kept. It will be removed once the make system uses only ifittool.

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
BUG=chromium:936768

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,

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.

The endian conversion function be32toh() is defined in
src/include/endian.h, however this file is not used for cbfstool
compilation. Currently the one provided by the host is used and if the
host does not provide this endian.h file, the build will fail.
However, we do have endian conversion functions in commonlib/endian.h
which is available for cbfstool compilation.
Switch from be32toh() to read_be32() in order to avoid relying on a
host provided include file.
We use functions from commonlib/endian.h already in cbfstool.

In order to support booting a GNU/Linux payload on non x86, the FIT format
should be used, as it is the defacto standard on ARM.
Due to greater complexity of FIT it is not converted to simple ELF format.
Add support for autodecting FIT payloads and add them as new CBFS_TYPE 'fit'.
The payload is included as is, with no special header.
The code can determine the type at runtime using the CBFS_TYPE field.
Support for parsing FIT payloads in coreboot is added in a follow on
commit.
Compression of FIT payloads is not supported, as the FIT sections might be
compressed itself.
Starting at this point a CBFS payload/ can be either of type FIT or SELF.
Tested on Cavium SoC.

This patch adds a new "rawcompress" command to cbfs-compression-tool,
that works exactly the same as "compress" except that it doesn't add the
custom 8-byte header to the file. This can be useful if you need to
compress something into a format that coreboot's decompression routines
can work with, but it's not supposed to go into CBFS.

This patch adds two minor improvements to the way cbfs-compression-tool
parses the compression algorithm type that is passed through the -t
option of the 'compress' subcommand. These improvements are intended
to prevent accidents and unexpected behavior when using the
cbfs-compression-tool, in particular in automated contexts such as a
Makefile rule.
In the first part of this patch, a return statement is inserted after
the 'if (algo->name == NULL)' check of the compress() function. This
causes the function to exit immediately and subsequently abort the
program when the algorithm type was not detected correctly. Previously,
execution would continue with the 'algo' pointer pointing to the zeroed
out stopper entry of the types_cbfs_compression[] array. The ultimate
effect of this would be to pass 0 as 'algo->type' to the
compression_function() function, which happens to be the same
enumeration value as is used for CBFS_COMPRESS_NONE, leading to a valid
compression function result that matches the behavior of no compression.
Thus, if a script calling cbfs-compression-tool compress contained a
typo in the -t parameter, it would continue running with an unintended
compression result rather than immediately exiting cleanly.
In the second part of this patch, the strcmp() function is replaced with
strcasecmp() when comparing 'algo->name' with the 'algoname' parameter
that was passed to the compress() function. strcasecmp() uses an
identical function signature as strcmp() and is thus suitable as a
drop-in replacement, but it differs in behavior: rather than only
returning a result of 0 when the two NULL-terminated input strings are
character by character identical, the strcasecmp() function applies a
weaker concept of identity where characters of the latin alphabet
(hexadecimal ranges 0x41 through 0x5a and 0x61 through 0x7a) are also
considered identical to other characters that differ from them only in
their case. This causes the -t parameter of cbfs-compression-tool
compress to also accept lowercase spellings of the available compression
algorithms, such as "lz4" instead of "LZ4" and "lzma" instead of "LZMA".
As an unintended but harmless side-effect, mixed-case spellings such as
"lZ4" or "LZmA" will also be recognized as valid compression algorithms.
(Note that since the character "4" (hexadecimal 0x34) of the "LZ4"
compression type name is not part of the above-mentioned ranges of latin
alphabet characters, no new substitutions become valid for that part of
the "LZ4" string with this patch.)
