Manuel Pégourié-Gonnard 282159c318 x509: CRL: add tests for malformed extensions 
This covers all lines added in the previous commit. Coverage was tested using:

    make CFLAGS='--coverage -g3 -O0'
    (cd tests && ./test_suite_x509parse)
    make lcov
    firefox Coverage/index.html # then visual check

Test data was generated by taking a copy of tests/data_files/crl-idp.pem,
encoding it as hex, and then manually changing the values of some bytes to
achieve the desired errors, using https://lapo.it/asn1js/ for help in locating
the desired bytes.

Manuel Pégourié-Gonnard b0ba5bccff Yet another dependency issue (PKCS1_V15) 
Found by running:

CC=clang cmake -D CMAKE_BUILD_TYPE="Check"
tests/scripts/depend-pkalgs.pl

(Also tested with same command but CC=gcc)

Another PR will address improving all.sh and/or the depend-xxx.pl scripts
themselves to catch this kind of thing.

Hanno Becker a5fa07958e Verify the result of RSA private key operations 
If RSA-CRT is used for signing, and if an attacker can cause a glitch
in one of the two computations modulo P or Q, the difference between
the faulty and the correct signature (which is not secret) will be
divisible by P or Q, but not by both, allowing to recover the private
key by taking the GCD with the public RSA modulus N. This is known as
the Bellcore Glitch Attack. Verifying the RSA signature before handing
it out is a countermeasure against it.

It's easier to identify and find by number than by its very wordy
title, especially as there was a typo in the title.

Andres Amaya Garcia 6451909160 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.
