3dafc6c3b3 pkcs7: Drop support for signature in contentInfo of signed data 
The contentInfo field of PKCS7 Signed Data structures can
optionally contain the content of the signature. Per RFC 2315
it can also contain any of the PKCS7 data types. Add test and
comments making it clear that the current implementation
only supports the DATA content type and the data must be empty.

Return codes should be clear whether content was invalid or
unsupported.

2a15a0c868 X.509: Remove red'n bounds checks and zeroiz'n in OtherName parsing 
- ASN.1 parsing functions check that length don't exceed buffer bounds,
  so checks `p + len > end` are redundant.
- If `p + len == end`, this is erroneous because we expect further fields,
  which is automatically caught by the next ASN.1 parsing call.

Hence, the two branches handling `p + len >= end` in x509_get_other_name()
can be removed.

Further, zeroization of the `other_name` structure isn't necessary
because it's not confidential (and it's also not performed on other
error conditions in this function).

af67d2c1cf mbedtls_mpi_sub_abs: Skip memcpy when redundant (#6701). 
In some contexts, the output pointer may equal the first input
pointer, in which case copying is not only superfluous but results in
"Source and destination overlap in memcpy" errors from Valgrind (as I
observed in the context of ecp_double_jac) and a diagnostic message
from TrustInSoft Analyzer (as Pascal Cuoq reported in the context of
other ECP functions called by cert-app with a suitable certificate).

a57cf9813a Implement and test mbedtls_mpi_mod_raw_random 
In the basic/XXX=core test cases, use odd upper bounds, because the mod
version of random() only supports odd upper bounds (the upper bound is a
modulus and the mod modules only support odd moduli).
