Host tools cert_tool and encrypt_fw refactored to be fully
compatible with OpenSSL v3.0.
Changes were made following the OpenSSL 3.0 migration guide:
https://www.openssl.org/docs/man3.0/man7/migration_guide.html
In some cases, those changes are straightforward and only
a small modification on the types or API calls was needed
(e.g.: replacing BN_pseudo_rand() with BN_rand(). Both identical
since v1.1.0).
The use of low level APIs is now deprecated. In some cases,
the new API provides a simplified solution for our goals and
therefore the code was simplified accordingly (e.g.: generating
RSA keys through EVP_RSA_gen() without the need of handling the
exponent). However, in some cases, a more
sophisticated approach was necessary, as the use of a context
object was required (e.g.: when retrieving the digest value from
an SHA file).

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

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

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.

Support for PKCS#1 v1.5 was deprecated in SHA 1001202 and fully removed
in SHA fe199e3, 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
with RSA now use the more modern padding scheme.

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.
For clarification, I inserted a blank line between headers from the
include/ directory (#include <...>) and ones from a local directory
(#include "..." ).

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);

With the introduction of commit `96103d5a`, the Certificate
Generation tool is not able to generate FWU certificate and
while doing so it does segmentation fault.
This happens because it is now required to pass non-volatile
counter values to the `cert_create` tool from the command line
for creating the trusted firmware certificates.
But in case of creating FWU certificate these counter values are not
being passed to the tool and as a consequence the `cert_create` tool
try to use the NULL argument and errors out with Segmentation fault.
This patch fixes this issue by providing a check before using the
command line argument passed in the case of `EXT_TYPE_NVCOUNTER`
certificate extension.
