Combined patch for the more or less obvious issues
Fixed a memory leak in ASN1_digest and ASN1_item_digest.
asn1_template_noexp_d2i call ASN1_item_ex_free(&skfield,...) on error.
Reworked error handling in asn1_item_ex_combine_new:
- call ASN1_item_ex_free and return the correct error code if ASN1_template_new failed.
- dont call ASN1_item_ex_free if ASN1_OP_NEW_PRE failed.
Reworked error handing in x509_name_ex_d2i and x509_name_encode.
Fixed error handling in int_ctx_new and EVP_PKEY_CTX_dup.
Fixed a memory leak in def_get_class if lh_EX_CLASS_ITEM_insert fails due to OOM:
- to figure out if the insertion succeeded, use lh_EX_CLASS_ITEM_retrieve again.
- on error, p will be NULL, and gen needs to be cleaned up again.
int_free_ex_data needs to have a fallback solution if unable to allocate "storage":
- if free_func is non-zero this must be called to clean up all memory.
Fixed error handling in pkey_hmac_copy.
Fixed error handling in ssleay_rand_add and ssleay_rand_bytes.
Fixed error handling in X509_STORE_new.
Fixed a memory leak in ssl3_get_key_exchange.
Check for null pointer in ssl3_write_bytes.
Check for null pointer in ssl3_get_cert_verify.
Fixed a memory leak in ssl_cert_dup.
