Changes to 'tools/cert_create' folder, to include platform defined
certificates, keys, and extensions.

NXP SoC lx2160a : based platforms requires additional
FIP DDR to be loaded before initializing the DDR.

To enable chain of trust on these platforms, FIP DDR
image needs to be authenticated, additionally.

Platform specific folder 'tools/nxp/cert_create_helper'
is added to support platform specific macros and definitions.

This bug manifests itself as a segfault triggered by a double-free.

I noticed that right before the double-free, the sk list contained 2
elements with the same address.

    (gdb) p sk_X509_EXTENSION_value(sk, 1)
    $34 = (X509_EXTENSION *) 0x431ad0
    (gdb) p sk_X509_EXTENSION_value(sk, 0)
    $35 = (X509_EXTENSION *) 0x431ad0
    (gdb) p sk_X509_EXTENSION_num(sk)
    $36 = 2

This caused confusion; this should never happen.

I figured that this was caused by a ext_new_xxxx function freeing
something before it is added to the list, so I put a breakpoint on
each of them to step through. I was suprised to find that none of my
breakpoints triggered for the second element of the iteration through
the outer loop just before the double-free.

Looking through the code, I noticed that it's possible to avoid doing
a ext_new_xxxx, when either:
   * ext->type == NVCOUNTER and ext->arg == NULL
   * ext->type == HASH and ext->arg == NULL and ext->optional == false
So I put a breakpoint on both.

It turns out that it was the HASH version, but I added a fix for both.
The fix for the Hash case is simple, as it was a mistake. The fix for
the NVCOUNTER case, however, is a bit more subtle. The NVCOUNTER may
be optional, and when it's optional we can skip it. The other case,
when the NVCOUNTER is required (not optinal), the `check_cmd_params`
function has already verified that the `ext->arg` must be non-NULL.
We assert that before processing it to covert any possible segfaults
into more descriptive errors.

This should no longer cause double-frees by adding the same ext twice.

Don't depend on clean when building, as the user is capable of cleaning
if required and this introduces a race where "all" depends on both the
compile and the clean in parallel.  It's quite possible for some of the
compile to happen in parallel with the clean, which results in the link
failing as objects just built are missing.

When OpenSSL's macro allocates the HASH struct, it allocates the fields
as well. After this allocation, the prior code would assign over the
pointers inside the HASH struct, leaking these fields. This patch
avoids allocating extra copies of these members.

Previously, we would leak these extensions as they are not freed by the
stack. An except from the `sk_TYPE_free` documentation:

    sk_TYPE_free() frees up the sk structure. It does not free up any
    elements of sk. After this call sk is no longer valid.

The fix is to drain the stack and free its elements before freeing the
stack. sk_TYPE_pop_free does this, so we use that instead.

Windows does not have a standard getopt implementation. To address
this an equivalent implementation has been provided in win_posix.c
However, the implementation has an issue with option processing as
described below.

Long option names may be abbreviated if the abbreviation is unique
or an exact match for some defined option.
Since some options can be substring of other options e.g. "scp-fw"
option is a substring of "scp-fwu-cfg", we need to identify if an
option is abbreviated and also check for uniqueness. Otherwise if
a user passes --scp-fw as an option, the "scp-fwu-cfg" option may
get selected, resulting in an incorrectly packaged FIP.

This issue has been be fixed by:
  - First searching for an exact match.
  - If exact match was not found search for a abbreviated match.
By doing this an incorrect option selection can be avoided.

Till now TF-A allows limited number of external images to be made part
of FIP. With SPM coming along, there may exist multiple SP packages
which need to be inserted into FIP. To achieve this we need a more
scalable approach to feed SP packages to FIP.

This patch introduces changes in build system to generate and add SP
packages into FIP based on information provided by platform.
Platform provides information in form of JSON which contains layout
description of available Secure Partitions.
JSON parser script is invoked by build system early on and generates
a makefile which updates FIP, SPTOOL and FDT arguments which will be
used by build system later on for final packaging.

"SP_LAYOUT_FILE" passed as a build argument and can be outside of TF-A
tree. This option will be used only when SPD=spmd.

For each SP, generated makefile will have following entries
     - FDT_SOURCES	+=	sp1.dts
     - SPTOOL_ARGS	+= 	-i sp1.img:sp1.dtb -o sp1.pkg
     - FIP_ARGS		+=	--blob uuid=XXXX-XXX...,file=SP1.pkg

Currently sptool generates a single blob containing all the Secure
Partitions, with latest SPM implementation, it is desirable to have
individual blobs for each Secure Partition. It allows to leverage
packaging and parsing of SP on existing FIP framework. It also allows
SP packages coming from different sources.

This patch modifies sptool so that it takes number of SP payload pairs
as input and generates number of SP blobs instead of a single blob.

Each SP blob can optionally have its own header containing offsets and
sizes of different payloads along with a SP magic number and version.
It is also associated in FIP with a UUID, provided by SP owner.

Usage example:
sptool -i sp1.bin:sp1.dtb -o sp1.pkg -i sp2.bin:sp2.dtb -o sp2.pkg ...

, however, cert_tool is still able to generate
certificates in that form. This patch fully removes the ability for
cert_tool to generate these certificates.

Additionally, this patch also fixes a bug where the issuing certificate
was a RSA and the issued certificate was EcDSA. In this case, the issued
certificate would be signed using PKCS#1 v1.5 instead of RSAPSS per
PKCS#1 v2.1, preventing TF-A from verifying the image signatures. Now
that PKCS#1 v1.5 support is removed, all certificates that are signed
