* scd/ccid-driver.c (intr_cb): Handle the case of multiple messages.
--
SPR532 USB Smart Card Reader (also know as SPR332) may send two
messages at once for a single interrupt transfer. An example transfer
observed was like: 50 03 50 02, which is considered valid, according
to the CCID specification.

For an existing database adding the new column to the table userid is
straightforward. However if the original version of the schema used an
integer for the keyid column, that column has likely be renamed. Make
sure that the NOT NULL constraint has also be removed; check the
SQLite documentation on how this can be done.

kbxutil is a debug tool but nevertheless it should behave well and not

This is helpful so that callers do not need to parse the key for this
basic information. Use "scd readkey --info-only" to return the info
status line instead of the key material; using just --info returns the
info in addition to the key material.

* kbx/backend-sqlite.c: Change definition of column KID.
(kid_from_mem): Remove.
(kid_from_u32): Rewrite.
(run_sql_bind_int64): Remove.
(run_select_statement): Implement lookup by short keyid. Fix lookup
by long keyid.
(store_into_fingerprint): Adjust kid arg.
--
The original idea of using an INTEGER, which has the required 64 bits,
didn't worked out due to problems with signed/unsigned mismatch and
the required truncation in a short keyid lookup. Thus we change the
definition to a blob.
For a database currently in use the change can be done by hand:
alter table fingerprint rename column kid to deletedkid;
alter table fingerprint add column kid not null
default X'0000000000000000';
update fingerprint set kid = substr (fpr, 13);
The update does only work with 20 octet fingerprints; that is not with
the new v5 OpenPGP keys. Note that sqlite does not allow to drip a
column, thus we rename it.

* doc/gnupg-module-overview.svg: Add examples of GPGME aware

This allows to compile time switch between the D-line and the
fd-passing data communication between gpg/gpgsm and keyboxd. A quick
test with about 3000 OpenPGP keys showed that D-lines are only 10%
slower than the fd-passing based implementation. Given that the
thread adds extra complexity we go for now with the D-line approach.

* dirmngr/server.c (cmd_killdirmngr): Return 0.

And we also print nicer diagnostics. The reason we need this is that

to an annoying error message from gpgconf.

* dirmngr/http.c (http_session_new) <gnutls>: Use only the special

The gnutls version uses a different strategy than the ntbtls version

so that we don't need to wonder about different kind of bug reports.
In short the special cert is now the only cert use with the default
keyserver.

In iobuf_read_line the parameter to pass and return the current buffer
length is controlled by the buffer parameter. Thus there should be no
problem because the assert call check s buffer first. For yet unknown
reasons when using the standard GNU libc assert valgrind complains
about an uninitialized variable. That does not happen with our
log_assert.

The data specific part of the code has been moved from gpg to a new
module in kbx/ so that it can also be used by gpgsm. The OpenPGP
parsing while reading the data has been replaced by storing the data
in memory and parse it later. That makes a nice interface and
abstracts the fd-passing/D-lines handling away.
