RFC4122 defines that fields are stored in network order (big endian),
but TF-A stores them in machine order (little endian by default in TF-A).
We cannot change the future UUIDs that are already generated, but we can store
all the bytes using arrays and modify fiptool to generate the UUIDs with
the correct byte order.

This patch updates the `fiptool` and `cert_create` for the
`hw_config` and `tb_fw_config` dynamic configuration files.
The necessary UUIDs and OIDs are assigned to these files and
the `cert_create` is updated to generate appropriate hashes
and include them in the "Trusted Boot FW Certificate". The
`fiptool` is updated to allow the configs to be specified
via cmdline and included in the generated FIP.

Updates are required to enable the fiptool utility to be built on a
Windows platform.  This change modifies the source files to enable
building with Visual Studio (detected via preprocessor settings).
The primary changes are:
  1.  Provide an implementation of the getopt_long function.  This does
      not exist in the Visual Studio CRT libraries because Windows
      commands normally use '/' not '-' as an option indicator.
  2.  Redirect some function names to match those supported by the
      Visual Studio libraries (when building with Visual Studio).
  2.  Modify a structure name (stat) to match that provided
      by the Visual Studio libraries (_stat).

Note - this change does not provide makefile updates.  It only modifies
       the sources to enable the fiptool to be built from a Visual
       Studio project.  In normal use the presence of FIPTOOL.EXE is
       enough to satisfy the make requirements.  A makefile change may
       be derived from the Visual Studio command line information at
       some point in the future.

This patch enables choice of RSA version at run time to be used for
generating signatures by the cert_tool. The RSA PSS as defined in
PKCS#1 v2.1 becomes the default version and this patch enables to specify
the RSA PKCS#1 v1.5 algorithm to `cert_create` through the command line
-a option. Also, the build option `KEY_ALG` can be used to pass this
option from the build system. Please note that RSA PSS is mandated
by Trusted Board Boot requirements (TBBR) and legacy RSA support is
being added for compatibility reasons.

Unix does not distinguish binary and text modes.
On Windows the 'b' flag (e.g. "rb" instead of "r") is used to
indicate that files should be opened in binary mode.
This has no impact on Unix, but is needed on Windows to avoid

Platforms aligned with TBBR are supposed to use their own OIDs, but
defining the same macros with different OIDs does not provide any
value (at least technically).

For easier use of TBBR, this commit allows platforms to reuse the OIDs
obtained by ARM Ltd.  This will be useful for non-ARM vendors that
do not need their own extension fields in their certificate files.

The OIDs of ARM Ltd. have been moved to include/tools_share/tbbr_oid.h

Platforms can include <tbbr_oid.h> instead of <platform_oid.h> by
defining USE_TBBR_DEFS as 1.  USE_TBBR_DEFS is 0 by default to keep the
backward compatibility.

Some header files need to be shared between TF and host programs.
For fiptool, two headers are copied to the tools/fiptool directory,
but it looks clumsy.

This commit introduces a new directory, include/tools_share, which
collects headers that should be shared between TF and host programs.

This will clarify the interface exposed to host tools.  We should
add new headers to this directory only when we really need to do so.

Currently, fiptool uses two linked lists.  One to chain together all
the images and one for all the image descriptors.  Initially this was
done because not all images had a corresponding image descriptor.
This was the case for unknown images which existed in the FIP but
there was no descriptor in the builtin table for them.  When support
for the --blob option came in, we started building descriptors for the
unknown images on the fly.  As a result every image now has a
corresponding image descriptor and therefore it is no longer necessary
to keep track of them separately.

To simplify the design, maintain only a single linked list of image
descriptors.  An image descriptor contains a pointer to the
corresponding image.  If the pointer is NULL, then the descriptor is
skipped in all the operations.  This approach simplifies the traversal
code and avoids redundant lookups.

The linked list of image descriptors is populated based on the
`toc_entries` array.  This means that the order of the images in the
FIP file remains the same across add/remove or create/update
operations.  This is true for all standard images (those specified in
`toc_entries`) but not for those specified via the --blob option.

In the current code, both key_load() and key_create() call key_new()
to allocate a key container (and they do not free it even if they
fail).  If a specific key is not given by the command option,
key_load() fails, then key_create() is called.  At this point, the
key container that has been allocated in key_load() is still alive,
and it is overwritten by a new key container created by key_create().

Move the key_new() call to the main() function to make sure it is
called just once for each descriptor.

While we are here, let's fix one more bug; the error handling code
  ERROR("Malloc error while loading '%s'\n", keys[i].fn);
is wrong because keys[i].fn is NULL pointer unless a specific key is
given by the command option.  This code could be run in either case.

The current fiptool packs all the images without any padding between
them.  So, the offset to each image has no alignment.  This is not
efficient, for example, when the FIP is read from a block-oriented
device.

For example, (e)MMC is accessed by block-addressing.  The block size
is 512 byte.  So, the best case is each image is aligned by 512 byte
since the DMA engine can transfer the whole of the image to its load
address directly.  The worst case is the offset does not have even
DMA-capable alignment (this is where we stand now).  In this case,
we need to transfer every block to a bounce buffer, then do memcpy()
from the bounce buffer to our final destination.  At least, this
should work with the abstraction by the block I/O layer, but the
CPU-intervention for the whole data transfer makes it really slow.

This commit adds a new option --align to the fiptool.  This option,
if given, requests the tool to align each component in the FIP file
by the specified byte.  Also, add a new Make option FIP_ALIGN for
easier access to this feature; users can give something like
FIP_ALIGN=512 from the command line, or add "FIP_ALIGN := 512" to
their platform.mk file.

The struct image has "uuid" and "size" to memorize the field values
they had in the TOC entry.  So, parse_fip() copies them from struct
fip_toc_entry to struct image, then pack_images() copies them back
to struct fip_toc_entry.

The next commit (support --align option) will require to save the
"offset" field as well.  This makes me realize that struct image
can embed struct fip_toc_entry.

This commit will allow the "flags" field to persevere the "update"
command.  At this moment, the "flags" is not used in a useful way.
(Yet, platforms can save their own parameters in the flags field.)
It makes sense to save it unless users explicitly replace the image.
