--
This patch improves the BER parser by simplifying it. Now tlv_next
pops off and thus closes all containers regardless on whether they are
length bounded or ndef. tlv_set_pending is now always used to undo
the effect of a tlv_next in a loop condition which was terminated by a
nesting level change.
Instead of using the length as seen in the decrypted container we now
remove the padding and let the BER parser do its work. This might
have a negative effect on pkcs#12 objects which are not correctly
padded but we don't have any example of such broken objects.

* scd/app-openpgp.c (check_keyidstr): Ignore the card version and also
compare case insensitive.
(do_learn_status): Add mssing error handling.
--
This is required because we changed what we emit as serialno of
OpenPGP cards but existing keys still use the old form of the serial
number (i.e. with a firmware version). This is so that existing stub
keys of gpg-agent will continue to work.

app_get_dispserialno.

--
There used to be a possible support of Ed25519 with ECDSA, (instead of
EdDSA). To distinguish key for Ed25519 for EdDSA, we use the
flag: (flags eddsa). Ed448 has no support for ECDSA and defaults to
EdDSA even if no such flag.

* scd/app-openpgp.c (struct app_local_s): Add new flag.
(get_cached_data): Force chace use if flag is set.
(app_select_openpgp): Avoid reading DO 6E multiple times.
--
The do not cache property of 6E was introduced so that we can change
for example key attributes without getting into with the cache.
However, for initial reading the cache makes a lot of sense and thus we
now use this hack to only temporary cache. A better strategy would be
to clear the cache when we change card data but that is more error
prone.

(dotlock_take_w32): Ditto.
--
In particular when using a dotlock file for protecting the spawning
and several processes try to spawn the agent or another component, we
often run into long delays. The solution is to is to exponential
backoff and also to reduce the initial delay from 50ms to 4ms. We
further limit the maximum wait period to about 2 seconds and then
repeat at intervals of 512, 1024 and 2048ms. In the wait-forever case
we add a small random value to have different intervals per process.

For testing this code snippet in the spawning function might be
useful:
const char *s;
if ((s=getenv("hold_gpg_file")))

gnupg_sleep (1);
* dirmngr/http.c (enum auth_negotiate_states): New.

(proxy_get_token): New. Implemented only for Windows for now.
(run_proxy_connect): Add support for auth method Negotiation.
(store_header): Keep some header lines separate.
--
The code does something but I have not yet been able to test it due
to problems setting up Squid with AD authentication. As of now it
will respond with a failure but that should not be worse than not to
implement Negotiation.
Supporting Negotiation using GSS for Unix should eventually also be
done.

Sometimes we have a short base64 encoded string we need todecode.
This function makes it simpler.
License change of the test module justified because I am the single

last_was_lf, and last_was_lfcr.
(http_context_s): Add field keep-alive.
(http_wait_response): Set up_to_empty_line. Take care of keep_alive
flag.
(coookie_read): Implement detection of empty lines.
(cookie_write): Free the pending buffer.
--
The problem we fix here is that we already buffered stuff beyond the
empty line which marks the start of the content-length counting. Thus
we tried to wait for more bytes despite that everything had already
been read. This bug might have showed up more often in the real world
since the we changed the BUFSIZ on Windows from 512 byte to 8k. It
also depends on the length of the headers and whether the server
closed the connection so that we ignored the Content-Length.
The bug was introduced earlier than 2010 and could have the effect
that a connection got stuck until the network layer timed out.
Note that the keep-alive parts of the patch are not yet used.
* dirmngr/http.c: Remove gnutls version specific code.
(send_request): Factor some code out to ...
(run_proxy_connect): new.

* configure.ac (NEED_GNUTLS_VERSION): Require 3.2.

This patch is to factor out some code and also to remove support for
legacy gnutls versions. Note that gnutls 3.2 was released 10 years
ago.

--
Note that this also removes some never used code. For example the
NTBTLS handshake has code taken from GNUTLS which was never used due
to the different ways on how the certificates are checked.
The proxy code has been factored out to make to prepare further
authentication methods. The proxy_info_t was introduced for the same
reason.
Tested against gnutls and ntbtls builds. No proxy tests yet done,
because we need more sophisticated tests anyway.
