* g10/call-agent.c (scd_genkey_cb_append_savedbytes): Remove.
(scd_genkey_cb): Only handle KEY-CREATED-AT and PROGRESS.
(agent_scd_genkey): Remove INFO argument.  CREATETIME is now in/out
argument.

* g10/keygen.c (gen_card_key): Use READKEY --card command of the agent
to retrieve public key information from card and let the agent make
a file for private key with shadow info.
--

This change removes gpg's KEY-DATA handling for SCD GENKEY.  Information
with KEY-DATA is simply not used.  Instead, it is read by READKEY --card
command of gpg-agent.  This can consolidate public key handling in a
single method by READKEY.

There are other smaller changes not described above.

This change tries to avoid new error messages so not to increase the
the number of translated strings or break too many existing
translations.  It also tries to use existing strings and changes the
quoting to the most common style used in gpg.

Key specifications should in general use double quotes.  Other values
should use single quotes.  However. sometimes it is not easy to
distinguish between values given on the command line and key
specifications.  According to old GNU coding standards diagnostics
should not start capitalized - whether this is a good idea is a
different thing but we used this rules for most strings.  However,
strings which are used interactively should be properly capitalized
and end with a dot.

Without a shadow key we can't create the self-signatures.  Thus we
need to issue the learn command after each key generation.

v3 keys are deprecated for about 15 years and due the severe
weaknesses of MD5 it does not make any sense to keep code around to
use these old and broken keys.  Users who need to decrypt old messages
should use gpg 1.4 and best re-encrypt them to modern standards.
verification of old (i.e. PGP2) created signatures is thus also not
anymore possible but such signatures have no values anyway - MD5 is
just too broken.

We have also kept support for v3 signatures until now.  With the
removal of support for v3 keys it is questionable whether it makes any
sense to keep support for v3-signatures.  What we do now is to keep
support for verification of v3-signatures but we force the use of
v4-signatures.  The latter makes the --pgp6 and --pgp7 switch a bit
obsolete because those PGP versions require v3-signatures for
messages.  These versions of PGP are also really old and not anymore
maintained so they have not received any bug fixes and should not be
used anyway.

* doc/gpg.texi: Document --enable-large-rsa.

This is a cherry-pick of 534e2876ac from
STABLE-BRANCH-1-4 against master

Some older implementations built and used RSA keys up to 16Kib, but
the larger secret keys now fail when used by more recent GnuPG, due to
secure memory limitations.

Building with ./configure --enable-large-secmem will make gpg
capable of working with those secret keys, as well as permitting the
use of a new gpg option --enable-large-rsa, which let gpg generate RSA
keys up to 8Kib when used with --batch --gen-key.

This patch adds two features:

1. The key for the last passphrase successfully used for unprotecting
a key is stored away.  On a cache miss the stored away passphrase is
tried as well.  This helps for the common GPG use case of having a
signing and encryption (sub)key with the same passphrase.  See the
code for more comments.

2. The now auto-generated revocation certificate does not anymore
popup a passphrase prompt.  Thus for standard key generation the
passphrase needs to be given only once (well, two with the
confirmation).

The use of PGP 2.c is considered insecure for quite some time

It was possible to create 16k RSA keys in batch mode. In addition to the
silliness of such keys, they have the major drawback that under GnuPG
and Libgcrypt, with their limited amount of specially secured memory
areas, the use of such keys may lead to an "out of secure memory"
condition.
