Fix incomplete checks for EVP_CIPHER_asn1_to_param

EVP_CIPHER_asn1_to_param() returns a value <= 0 in case of an error, and
a value greater than 0 in case of success. Two callsites only check for
< 0 instead of <= 0. The other callsites perform this check correctly.
Change the two callsites to <= 0. Additionally correctly handle a zero
return value from EVP_CIPHER_get_asn1_iv as success.

Fix corruption when searching for CRLs in hashed directories

The by_dir certificate/CRL lookup code uses an OPENSSL_STACK to track
how many sequentially numbered CRL files have been loaded for a given
X509_NAME hash which is being requested. This avoids loading already
loaded CRL files and repeated stat() calls.

This OPENSSL_STACK is searched using sk_find, however this mutates
the OPENSSL_STACK unless it is known to be sorted. This operation
therefore requires a write lock, which was not taken.

Fix this issue by sorting the OPENSSL_STACK whenever it is mutated. This
guarantees no mutation will occur during sk_find. This is chosen over
taking a write lock during sk_find as retrieving a CRL by X509_NAME is
assumed to be a hotter path than the case where a new CRL is installed.

Also optimise the code by avoiding creating the structure to track the
last CRL file sequence number in the circumstance where it would match
the initial value, namely where no CRL with the given hash is installed.

PKCS12 - Add additional libctx and propq support.

Fixes #19718
Fixes #19716

Added PKCS12_SAFEBAG_get1_cert_ex(), PKCS12_SAFEBAG_get1_crl_ex() and
ASN1_item_unpack_ex().

parse_bag and parse_bags now use the libctx/propq stored in the P7_CTX.
PKCS12_free() needed to be manually constructed in order to free the propq.

pkcs12_api_test.c changed so that it actually tests the libctx, propq.
