agent: Fix alignment problem with the second passphrase struct.
* agent/genkey.c (agent_ask_new_passphrase): Use a separate malloc for
PI2.  Check return value of the malloc function.
* agent/command-ssh.c (ssh_identity_register): Use a separate malloc
for PI2.  Wipe PI2.
--

For whatever stupid reasons I once allocated only one memory area and
split that into PI and PI2.  This is actually a common pattern with
malloc but here we used a made up object size and do not take the
extra alignment required into account.  One of these not yet hit by
a (sig)bus PC/VAX hacker bugs.

Instead of trying to fix the alignment, it is better to use a second
calloc for the second struct.

smartcards, gpg-agent does signature verification.

In 2.1 this function is only used at one place and the stdin parameter
is not used.  Thus this change is trivial for the callers but along
with estream's new es_poll it is overall simpler to use.

Note that the Windows version has not been tested.

gpg: Report a conflict between honor-keyserver-url and TOR.
* g10/call-dirmngr.c (create_context): Send option and print a verbose
error.
--

It is in general a bad idea to use honor-keyserver-url but if Dirmngr
is running in TOR mode we should not allow this option at all.  We let
Dirmngr know about the use of this option and let Dirmngr tell use
whether TOR mode is active so that we can print a hint to disable that
keyserver option.

A future extension in gpgconf may disable that option directly but a
user may still override that and thus we better check.

--
Signed-off-by: Neal H. Walfield <neal@g10code.com>.

The keybox code doesn't work directly with keyblocks.  As such, the
matched user packet is not readily available to pass to
DESC[n].SKIPFNC.  But, we do know the index of the user id packet that
matched.  Thus, pass that instead.  If the skip function needs the
user id packet, it can use the key id to look up the key block and
find the appropriate packet.
