We should have a better notification service from scdaemon to make

bit course but sufficient.

This has been tested with gpgsm and RSA keys. For ECC keys only
partly tested using the sample OpenPGP nistp256 and nistp384 keys
because gpgsm does not yet support ECC certificates and thus we can't
write the certificates to the cert object after a writekey. Note that
they nevertheless show up in "gpgcard list" because gpg-card searches
for them in gpg and gpgsm. However, this does not work completely.

This fixes a potential overflow if LFs are passed to the status
string functions. This is actually not the case and would be wrong
because neither the truncating in libassuan or our escaping is not the
Right Thing. In any case the functions need to be more robust and
comply to the promised interface. Thus the code has been factored out
to a helper function and N has been bumped up correctly and checked in
all cases.
For some uses this changes the behaviour in the error case (i.e. CR or
LF passed): It will now always be C-escaped and not passed to
libassuan which would truncate the line at the first LF.

This also requires an update to pinentry to handle the new uid field.
Distributing the uid as well as the pid makes it harder for a
different user on the same machine to take advantage of any race
conditions between when a requesting process might ask for something
that needs pinentry, and when pinentry gets around to inspecting the
state of that process.
We put the uid before the nodename because the uid is guaranteed to be
a integer (represented in decimal), which makes it much simpler to
parse past than the potentially arbitrarily structured nodename.
Use a / instead of whitespace to delimit pid/uid at Werner's request.
If we were willing to depend on the nodename being
whitespace-delimited (as the current, unreleased pinentry code does),
then we could add the uid after the nodename. But since no released
pinentry depends on this option anyway, i think we should make the
more conservative, easily-parseable choice and put the user ID first.

Decryption using a card never worked in gpg 2.1 because the

available. Gpg < 2.1 too this info from the secret sub key but that
has gone in 2.1.

With the gpg-agent taking care of the secret keys, the user needs to
migrate existing keys from secring.gpg to the agent. This and also
the standard import of secret keys required the user to unprotect the
secret keys first, so that gpg-agent was able to re-protected them
using its own scheme. With many secret keys this is quite some
usability hurdle. In particular if a passphrase is not instantly
available.
To make this migration smoother, this patch implements an unattended
key import/migration which delays the conversion to the gpg-agent
format until the key is actually used. For example:
gpg2 --batch --import mysecretkey.gpg
works without any user interaction due to the use of --batch. Now if
a key is used (e.g. "gpg2 -su USERID_FROM_MYSECRETKEY foo"), gpg-agent
has to ask for the passphrase anyway, converts the key from the
openpgp format to the internal format, signs, re-encrypts the key and
tries to store it in the gpg-agent format to the disk. The next time,
the internal format of the key is used.
This patch has only been tested with the old demo keys, more tests
with other protection formats and no protection are needed.

* agent/command.c (cmd_import_key): Pass 0 instead of KEYLEN to
gcry_sexp_canon_len.
--
We used to pass KEYLEN to the gcry_sexp_canon_len for no good reason:
convert_from_openpgp is guaranteed to return a valid canonical
S-expression and KEYLEN would thus act only as an upper limit. This
is not a problem because usually the original input key is longer than
the returned unprotected key. A future patch may change this
assertion and thus we better fix this bug now.
