gpgsm: Allow parsing of PKCS#12 files with two private keys.
* sm/minip12.c (struct p12_parse_ctx_s): Add privatekey2.
(parse_shrouded_key_bag): Handle a second private key.
(p12_parse_free_kparms): New.

* sm/import.c (parse_p12): Factor some code out to ...
(p12_to_skey): this.
(parse_p12): Use p12_parse_free_kparms.

Take care: We allow parsing of a second private key but we are not yet
able to import the second private key.

The whole things is required to at least import the certificates of
current pkcs#12 files as created by the German Elster tax system.  No
test data, sorry.

This supports the modern algorithms, i.e. using SHA256 for the KDF
which is the default in openssl unless the -legacy option is used.

(tlv_register_buffer): New.
(tlv_release): Release bufferlist.
(tlv_expect_object): Handle octet string cramming.
(tlv_expect_octet_string): Ditto.
(cram_octet_string): Changed interface.  We don't need the
input_consumed value anymore.

* sm/minip12.c (parse_shrouded_key_bag): Also parse the attribute set.

* sm/t-minip12.c (main): Add option --no-extra.
(cert_collect_cb, run_tests_from_file): Fix memory leak

* tests/cms/samplekeys/t5793-openssl.pfx: New from T5793.
* tests/cms/samplekeys/t5793-test.pfx: Ditto.
* tests/cms/samplekeys/Description-p12: Add them.
* tests/cms/Makefile.am (EXTRA_DIST): Add samplekeys.

This should finish the rewrite of the pkcsc#12 parser for now.  More
fun is likely to come.

sm: Major rewrite of the PKCS#12 parser
* sm/minip12.c: Reworked most of the parser.

Note that cram_octet_string stuff has not yet been reworked.  I need
to locate the sample files first.
