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.

We now cache the userids using the fingerprint.  This allows to print
the correct user id for keys with a duplicated key id.  We should
eventually start to retire the use of all the old keyid based
functions.  However, at some places we only have the keyid and thus
some of them will need to be kept (maybe changed with an indication to
show that more than several user ids are matching).

--

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.

The problem was reported by dkg on gnupg-devel (2014-10-07):

  I just discovered a new problem, though, which will affect people on
  systems that have gpg and gpg2 coinstalled:

   0) create a new keyring with gpg2, and use it exclusively with gpg2
  for a while.
   1) somehow (accidentally?) use gpg (1.4.x) again -- this creates
  ~/.gnupg/pubring.gpg
   2) future runs of gpg2 now only look at pubring.gpg and ignore
  pubring.kbx -- the keys you had accumulated in the keybox are no
  longer listed in the output of gpg2 --list-keys

Note that gpgsm has always used pubring.kbx and thus this file might
already be there but without gpg ever inserted a key.  The new flag in
the KBX header gives us an indication whether a KBX file has ever been
written by gpg >= 2.1.  If that is the case we will use it instead of
the default pubring.gpg.

In the course of building GnuPG 2.1.0 beta864 on debian, i found that
several of the installed executables were linked to libraries that
they did not need to be linked to, which would cause unnecessary
package dependencies at runtime.

The changeset here removes these unnecessary libraries from linking.

Something similar could possibly also be done by passing --as-needed
to the linker, but trimming the depenencies seems more parsimonious.

In gpg2, the following options are only relevant for scdaemon:

 reader-port
 ctapi-driver
 pcsc-driver
 disable-ccid

but in gpg1, they are options for gpg itself.

Some users of gpg1 might have these options in their
~/.gnupg/gpg.conf, which causes gpg2 to fail hard if it reads that
config file.

gpg2 should not fail hard, though giving a warning (and suggesting a
move to scdaemon.conf) seems OK.

This patch does *not* reintroduce any documentation for these options
in gpg.texi, even to indicate that they are "dummy" options, since
scdaemon.texi contains the appropriate documentation.
