849bc65bbf Fix x509_get_subject_alt_name to drop invalid tag
Fix the x509_get_subject_alt_name() function to not accept invalid
tags. The problem was that the ASN.1 class for tags consists of two
bits. Simply doing bit-wise and of the CONTEXT_SPECIFIC macro with the
input tag has the potential of accepting tag values 0x10 (private)
which would indicate that the certificate has an incorrect format.

3f81691d29 Revert to old behaviour of profile_check_key()
Was never documented to check for key alg compatibility, so should not start
doing so. Just stop relying on the pk_alg argument instead.

08c36635cb Avoid possible miscast of PK key
I don't think this can cause a crash as the member accessed is in the
beginning of the context, so wouldn't be outside of valid memory if the actual
context was RSA.

Also, the mismatch will be caught later when checking signature, so the cert
chain will be rejected anyway.

daf049144e Rework state saving for verify_chain()
Child was almost redundant as it's already saved in ver_chain, except it was
multiplexed to also indicate whether an operation is in progress. This commit
removes it and introduces an explicit state variable instead.

This state can be useful later if we start returning IN_PROGRESS at other
points than find_parent() (for example when checking CRL).

Note that the state goes none -> find_parent and stays there until the context
is free(), as it's only on the first call that nothing was in progress.

15d7df2ba8 Introduce mbedtls_pk_restart_ctx and use it
The fact that you needed to pass a pointer to mbedtls_ecdsa_restart_ctx (or
that you needed to know the key type of the PK context) was a breach of
abstraction.

Change the API (and callers) now, and the implementation will be changed in
the next commit.

d19a41d9aa Add tests for verify_restartable()
For selection of test cases, see comments added in the commit.

It makes the most sense to test with chains using ECC only, so for the chain
of length 2 we use server10 -> int-ca3 -> int-ca2 and trust int-ca2 directly.

Note: server10.crt was created by copying server10_int3_int-ca2.crt and
manually truncating it to remove the intermediates. That base can now be used
to create derived certs (without or with a chain) in a programmatic way.

c547d1ab1f Start using an explicit stack for callback info
This is the first step towards making verify_chain() iterative. While from a
readability point of view the current recursive version is fine, one of the
goals of this refactoring is to prepare for restartable ECC integration, which
will need the explicit stack anyway.

8f8c282de9 Merge near-duplicated (grand)parent finding code
Besides avoiding near-duplication, this avoids having three generations of
certificate (child, parent, grandparent) in one function, with all the
off-by-one opportunities that come with it.

This also allows to simplify the signature of verify_child(), which will be
done in next commit.
