This should always work because the dirmngr asked us to validate the
given certificate. This should make OCSP configuration easier because
there is less requirement to install all certificates for Dirmngr and
gpgsm.
CAUTION: This code has not yet been tested.
This patch implementes a chunk mode to pass the key parameters from
scdaemon to gpg. This allows to pass arbitrary long key paremeters;
it is used for keys larger than 3072 bit.
Fabian Keil found the reason for a SIGBUS:
In the "gpg-agent --daemon" case, main() calls pth_kill()
after the client has been forked, so when es_deinit() is
called on exit, acquiring the estream_list_lock seems to
cause pth to dereference a pointer located in a memory
region that has previously been free()'d.
My approach to fix it is different than his suggestion. It should
allow to continue all estream operations after a pth_kill except for
restarting pth.
From Grant Olsons's mail to gnupg-devel@:
This is three-quarters NIIBE and one-quarter me, but I though it would
be easier to have a single complete patch that applies to
STABLE-BRANCH-2-0 than two patches floating around.
This is basically NIIBE Yatuka's patch here:

Plus another check that closes down the reader explicitly if we get a
SW_HOST_NO_READER error, so that an unplugged reader doesn't hold onto
the first slot, preventing us from getting to the active plugged reader.
overflow when picking an algorithm (not a security issue since we
can't pick something not present in all preference lists, but we might
pick something that isn't scored first choice).
* pkclist.c (select_algo_from_prefs): Slightly improve the handling of
MD5 in preference lists. Instead of replacing MD5 with SHA-1, just
remove MD5 from the list altogether, and let the next-highest ranked
algorithm be chosen.
