Introduce ASN.1 API for traversing ASN.1 SEQUENCEs
...
This commit adds a new function `mbedtls_asn1_traverse_sequence_of()`
which traverses an ASN.1 SEQUENCE and calls a user-provided callback
for each entry.
It allows to put the following constraints on the tags allowed
in the SEQUENCE:
- A tag mask and mandatory tag value w.r.t. that mask.
A non-matching tag leads to an MBEDTLS_ERR_ASN1_UNEXPECTED_TAG error.
For example, it the mask if 0xFF, this means that only
a single tag will be allowed in the SEQUENCE.
- A tag mask and optional tag value w.r.t. that mask.
A non-matching tag is silently ignored.
The main use for this flexibility is the traversal of the
`SubjectAlternativeNames` extension, where some parts of the
tag are fixed but some are flexible to indicate which type
of name the entry describes.

Reduce code-size of mbedtls_asn1_get_alg()
...
The previous code
- checked that at least 1 byte of ASN.1 tag data is available,
- read and stored that ASN.1 tag,
- called the ASN.1 parsing function, part of which is checking
that enough space is available and that the ASN.1 tag matches
the expected value MBEDTLS_ASN1_OID.
Since the ASN.1 parsing function includes bounds checks,
this can be streamlined to:
- call the ASN.1 parsing function directly,
- on success, store MBEDTLS_ASN1_OID in the tag field.
This commit applies this simplification to mbedtls_asn1_get_alg().

Remove individual copies of mbedtls_zeroize()

This commit removes all the static occurrencies of the function
mbedtls_zeroize() in each of the individual .c modules. Instead the
function has been moved to utils.h that is included in each of the
modules.

- Changed the behaviour of x509parse_parse_crt for permissive parsing. Now returns the number of 'failed certificates' instead of having a switch to enable it.
...
- As a consequence all error code that were positive were changed. A lot of MALLOC_FAILED and FILE_IO_ERROR error codes added for different modules.
- Programs and tests were adapted accordingly
