for a non-existing trustdb.  Change all callers to to pass False for
NO_CREATE.

Due to user experience problems with the keyid and we better allow to

anymore and thus there is no technical need for a user to know the
keyid.

gpg: Fail decryption for AES etc message w/o MDC.
* g10/mainproc.c (proc_encrypted): Fail for modern messages w/o MDC.
--

This change turns the missing MDC warning into an error if the message
has been encrypted using a cipher with a non-64 bit block length cipher
and it is not Twofish.

We can assume that such messages are created by code which should have
been able to create MDC packets.  AES was introduced with 1.0.3 on
2000-09-18 shortly after MDC (1.0.2 on 2000-07-12).  We need to
exclude Twofish because that might have been used before MDC.

the logging code and because we need TCP for our socket emulation
under Windows.  Probably also required for Solaris etc.

Note that although PKA is now always build, it will only work if
support for looking up via DNS has not been disabled.

The new PKA only works with the IPGP DNS certtype and shall be used
only to retrieve the fingerprint and optional the key for the first
time.  Due to the security problems with DNSSEC the former assumption
to validate the key using DNSSEC is not anymore justified.  Instead an
additional layer (e.g. Trust-On-First-Use) needs to be implemented to
track change to the key.  Having a solid way of getting a key matching
a mail address is however a must have.

More work needs to go into a redefinition of the --verify-options
pka-lookups and pka-trust-increase.  The auto-key-locate mechanism
should also be able to continue key fetching with another methods once
the fingerprint has been retrieved with PKA.

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.

--

Allowing to use the abbreviated form for detached signatures is a long
standing bug which has only been noticed by the public with the
release of 2.1.0.  :-(

What we do is to remove the ability to check detached signature in
--batch using the one file abbreviated mode.  This should exhibit
problems in scripts which use this insecure practice.  We also print a
warning if a matching data file exists but was not considered because
the detached signature was actually a standard signature:

  gpgv: Good signature from "Werner Koch (dist sig)"
  gpgv: WARNING: not a detached signature; \
  file 'gnupg-2.1.0.tar.bz2' was NOT verified!

We can only print a warning because it is possible that a standard
signature is indeed to be verified but by coincidence a file with a
matching name is stored alongside the standard signature.
