The cbfs_locate_entry() function had a hack in there which
assumed a struct cbfs_stage data was being added in addition
to the struct cbfs_file and name. Move that logic out to the
callers while still maintaining the logic for consistency.
The only impacted commands cbfs_add and cbfs_locate, but
those are using the default 'always adding struct cbfs_stage'
in addition to cbfs_file + name. Eventually those should be
removed when cbfs_locate is removed as cbfs_add has no smarts
related to the cbfs file type provided.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

The cbfstool handling of new-style FMAP-driven "partitioned" images
originally disallowed the use of x86-style top-aligned addresses with
the add.* and layout actions because it wasn't obvious how they should
work, especially since the normal addressing is done relative to each
individual region for these types of images. Not surprisingly,
however, the x86 portions of the build system make copious use of
top-aligned addresses, so this allows their use with new images and
specifies their behavior as being relative to the *image* end---not
the region end---just as it is for legacy images.

These new-style firmware images use the FMAP of the root of knowledge
about their layout, which allows them to have sections containing raw
data whose offset and size can easily be determined at runtime or when
modifying or flashing the image. Furthermore, they can even have
multiple CBFSes, each of which occupies a different FMAP region. It is
assumed that the first entry of each CBFS, including the primary one,
will be located right at the start of its region. This means that the
bootblock needs to be moved into its own FMAP region, but makes the
CBFS master header obsolete because, with the exception of the version
and alignment, all its fields are redundant once its CBFS has an entry
in the FMAP. The version code will be addressed in a future commit
before the new format comes into use, while the alignment will just be
defined to 64 bytes in both cbfstool and coreboot itself, since
there's almost no reason to ever change it in practice. The version
code field and all necessary coreboot changes will come separately.

The buffer API that cbfstool uses to read and write files only directly supports
one-shot operations on whole files. This adds an intermediate partitioned_file
module that sits on top of the buffer system and has an awareness of FMAP
entries. It provides an easy way to get a buffer for an individual region of a
larger image file based on FMAP section name, as well as incrementally write
those smaller buffers back to the backing file at the appropriate offset. The
module has two distinct modes of operation:
- For new images whose layout is described exclusively by an FMAP section, all
the aforementioned functionality will be available.
- For images in the current format, where the CBFS master header serves as the
root of knowledge of the image's size and layout, the module falls back to a
legacy operation mode, where it only allows manipulation of the entire image
as one unit, but exposes this support through the same interface by mapping
the region named SECTION_NAME_PRIMARY_CBFS ("COREBOOT") to the whole file.
The tool is presently only ported onto the new module running in legacy mode:
higher-level support for true "partitioned" images will be forthcoming. However,
as part of this change, the crusty cbfs_image_from_file() and
cbfs_image_write_file() abstractions are removed and replaced with a single
cbfs_image function, cbfs_image_from_buffer(), as well as centralized image
reading/writing directly in cbfstool's main() function. This reduces the
boilerplate required to implement each new action, makes the create action much
more similar to the others, and will make implementing additional actions and
adding in support for the new format much easier.

This patches a memory leak on every struct cbfs_image creation that
was introduced by c1d1fd850ee7b8e52bd2ea5064fab68ac0c27098. Since that
commit, the CBFS master header has been copied to a separate buffer so
that its endianness could be fixed all at once; unfortunately, this
buffer was malloc()'d but never free()'d. To address the issue, we
replace the structure's struct cbfs_header * with a struct cbfs_header
to eliminate the additional allocation.

This enables more warnings on the cbfstool codebase and fixes the
issues that surface as a result. A memory leak that used to occur
when compressing files with lzma is also found and fixed.
Finally, there are several fixes for the Makefile:
- Its autodependencies used to be broken because the target for
the .dependencies file was misnamed; this meant that Make
didn't know how to rebuild the file, and so would silently
skip the step of updating it before including it.
- The ability to build to a custom output directory by defining
the obj variable had bitrotted.
- The default value of the obj variable was causing implicit
rules not to apply when specifying a file as a target without
providing a custom value for obj.
- Add a distclean target for removing the .dependencies file.

The new command allows to create a file where the original CBFS image
is duplicated at a different offset.
The required options of the new command are -D, the offset where the
copy CBFS header is placed, and -s, the size of the new CBFS copy.
When a CBFS is copied, the bootblock area of the source CBFS is
ignored, as well as empty and deleted files in the source CBFS. The
size of the destination CBFS is calculated as the rombase size of the
source CBFS less the bootblock size.
The copy instance can be created in the image only above the original,
which rules out the use of this new command for x86 images. If
necessary, this limitation could be addressed later.
As with other cbfstool commands, unless explicitly specified the
lowest CBFS instance in the image is considered the source. If
necessary, the user can specify the source CBFS using the -H option.

There potentially could be multiple CBFS instances present in the
firmware image. cbfstool should be able to operate on any of them, not
just the first one present.
To accomplish that, allow all CBFS commands to accept the -H parameter
(which specifies the exact CBFS header location in the image).
If this parameter is specified, the image is not searched for the CBFS
header, only the specified location is checked for validity, If the
location is valid, it is considered to be the CBFS header, if not -
the tool exits with an error status.
Note, that default behavior of the tool does not change.

Rather than using [hn]to[nh] whenever accessing a member of the CBFS
header, deserialize the header when opening the CBFS image. The header
is no longer a pointer inside the CBFS buffer, but a separate struct,
a copy of the original header in a host-friendly format. This kills
more of the ntohl usage.

This change adds a header serialization function. Programmers can thus just
set up a header as needed, without worrying about forgetting if and how to
use the [hn]to[hn]* functions.
In the long term, we will work to remove swab.h, i.e. we need to get to the
point where programmers don't have to try to remember [hn]to[nh]* and where
it goes. To date, even the best programmers we have have made an error with
those functions, and those errors have persisted for 6 or 7 years now. It's
very easy to make that mistake.
BUG=None
TEST=Build a peppy image and verify that it's bit for bit the same. All

cbfstool usage change:
"-a" for "cbfstool locate" can specify base address alignment.
To support putting a blob in aligned location (ex, microcode needs to be aligned
in 0x10), alignment (-a) is implemented into "locate" command.
Verified by manually testing a file (324 bytes) with alignment=0x10:
cbfstool coreboot.rom locate -f test -n test -a 0x10
# output: 0x71fdd0
cbfstool coreboot.rom add -f test -n test -t raw -b 0x71fdd0
cbfstool coreboot.rom print -v -v
# output: test 0x71fd80 raw 324
# output: cbfs_file=0x71fd80, offset=0x50, content_address=0x71fdd0+0x144
Also verified to be compatible with old behavior by building i386/axus/tc320
(with page limitation 0x40000):
cbfstool coreboot.rom locate -f romstage_null.bin -n romstage -P 0x40000
# output: 0x44
cbfstool coreboot.rom locate -f x.bin -n romstage -P 0x40000 -a 0x30
# output: 0x60

On platforms with CBFS data filling end of ROM image without bootblock in the
end (ex, ARM), calculation of "next valid entry" may exceed ROM image buffer in
memory and raise segmentation fault when we try to compare its magic value.
To fix this, always check if the entry address is inside ROM image buffer.
Verified to build and boot successfully on qemu/x86 and armv7/snow.

The "add" command is compatible with all legacy usage. Also, to support
platforms without top-aligned address, all address-type params (-b, -H, -l) can
now be ROM offset (address < 0x8000000) or x86 top-aligned address (address >
0x80000000).
Example:
cbfstool coreboot.rom add -f config -n config -t raw -b 0x2000
cbfstool coreboot.rom add -f stage -n newstage -b 0xffffd1c0
Verified boot-able on both ARM(snow) and x86(QEMU) system.

Usage Changes: To support platforms with different memory layout, "create" takes
two extra optional parameters:
"-b": base address (or offset) for bootblock. When omitted, put bootblock in
end of ROM (x86 style).
"-H": header offset. When omitted, put header right before bootblock,
and update a top-aligned virtual address reference in end of ROM.
Example: (can be found in ARM MAkefile):
cbfstool coreboot.rom create -m armv7 -s 4096K -B bootblock.bin \
-a 64 -b 0x0000 -H 0x2040 -o 0x5000
Verified to boot on ARM (Snow) and X86 (QEMU).

To support platforms without top-aligned address mapping like ARM, "locate"
command now outputs platform independent ROM offset by default. To retrieve x86
style top-aligned virtual address, add "-T".
To test:
cbfstool coreboot.rom locate -f stage -n stage -a 0x100000 -T
# Example output: 0xffffdc10

Current cbfstool implementation is relying on global variables to pass processed
data, and the calculation of address is based on x86 architecture (ex, always
assuming 0x0000 as invalid address), not easy to be used on platforms without
top-aligned memory mapping. This CL is a first step to start a new cbfstool
without global variables, and to prevent assuming memory layout in x86 mode.
The first published APIs are for reading and writing existing CBFS ROM image
files (and to find file entries in a ROM file).
Read cbfs_image.h for detail usage of each API function.
