Reported-by: Guilhem Moulin <guilhem@fripost.org>

  Needed for unattended key edits with --status-fd, because since 2.1
  status prompts are preceded by es_fflush (in cpr.c:do_get_from_fd)
  not fflush(3), so the standard output may not be flushed before each
  prompt. (Which breaks scripts using select(2) to multiplex between
  the standard and status outputs.)

His patch only affected print_and_check_one_sig_colon() but there are
many more places where stdio and estream are mixed.  This patch now
replaces most of them in g10/.  At some places stdio is still used,
but that is local to a function and should not have side effects.

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.

This patch separates Libgcrypt and OpenPGP public key algorithms ids
and in most cases completely removes the Libgcrypt ones.  This is
useful because for Libgcrypt we specify the algorithm in the
S-expressions and the public key ids are not anymore needed.

This patch also adds some support for PUBKEY_ALGO_EDDSA which will
eventually be used instead of merging EdDSA with ECDSA.  As of now an
experimental algorithm id is used but the plan is to write an I-D so
that we can get a new id from the IETF.  Note that EdDSA (Ed25519)
does not yet work and that more changes are required.

The ECC support is still broken right now.  Needs to be fixed.

This new features allows to use gpg without a Pinentry.  As a
prerequisite the agent must be configured to allow the loopback
pinentry mode (option --allow-loopback-pinentry).  For example

  gpg2 --pinentry-mode=loopback FILE.gpg

may be used to decrypt FILE.gpg while entering the passphrase on the
tty.  If batch is used, --passphrase et al. may be used, if
--command-fd is used, the passphrase may be provided by another
process.  Note that there are no try-again prompts in case of a bad
passphrase.

096e7457ec Change all quotes in strings and comments to the new GNU standard.
The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems.  We now use two \x27 characters ('...').

The proper solution would be to use the correct Unicode symmetric
quotes here.  However this has the disadvantage that the system
requires Unicode support.  We don't want that today.  If Unicode is
available a generated po file can be used to output proper quotes.  A
simple sed script like the one used for en@quote is sufficient to
change them.

The changes have been done by applying

  sed -i "s/\`\([^'\`]*\)'/'\1'/g"

to most files and fixing obvious problems by hand.  The msgid strings in
the po files were fixed with a similar command.
