g10,sm: Use gnupg_access at two more places

Replace most calls to open by a new wrapper.
* common/sysutils.c (any8bitchar) [W32]: New.
(gnupg_open): New.  Replace most calls to open by this.
* common/iobuf.c (any8bitchar) [W32]: New.
(direct_open) [W32]: Use CreateFileW if needed.

This is yet another step for full Unicode support on Windows.

Replace most of the remaining stdio calls by estream calls.
--

We need to use es_fopen on Windows to cope with non-ascii file names.
This is quite a large but fortunately straightforward change.  At a
very few places we keep using stdio (for example due to the use of
popen).

keyboxd: Use D-lines instead of a separate thread.

* g10/call-keyboxd.c (open_context): Set DLINES to true.

This allows to compile time switch between the D-line and the
fd-passing data communication between gpg/gpgsm and keyboxd. A quick
test with about 3000 OpenPGP keys showed that D-lines are only 10%
slower than the fd-passing based implementation.  Given that the
thread adds extra complexity we go for now with the D-line approach.

This could in theory result in reading bytes after a after Nul in a

parts of the memory.  However, it is harmless because the rfc2253

sm: Try not to output a partial new message after an error.
* sm/gpgsm.c (main) <aSign,aEncr>:  Uses gpgrt_fcancel on error.
--

When creating a signature or encrypting and the respective key is not
available or the user canceled the PIN entry gpgsm prints the initial
part of the message due to internal buffering in gpgrt.  By using
gpgrt_fcancel we can avoid this at least as long as the data is less
than the standard buffer size (which is currently 8k).  If is not a
complete solution but the best we can do easily.  Outputting to the
tty is anyway more of a testing aid than for real use.

This makes use of the new gpgrt_fcancel API.

I did some test against

  Governikus_Signer:       2.9.2.0
  MCard security Provider: 2.4.0
  Algorithm catalog from:  05.12.2019

using a Signature Card v2.0 and a nistp256 certificate.  Encrypting
with Governikus used the stdDH-sha1kdf scheme which we can now
decrypt.  Encrypting with GPGSM uses for that curve the recommended
scheme sha256kdf but Governikus was not able to decrypt this (no
usable error message).  Encrypting using stdDH-sha1kdf with GPGSM by
using the new --debug-force-ecdh-sha1kdf option showed that
Governikus was able to decrypt this.

FWIW: RFC5753 (Use of Elliptic Curve Cryptography (ECC) Algorithms)
has this requirement:

   Implementations that support EnvelopedData with the
   ephemeral-static ECDH standard primitive:

   - MUST support the dhSinglePass-stdDH-sha256kdf-scheme key
     agreement algorithm, the id-aes128-wrap key wrap algorithm, and
     the id-aes128-cbc content encryption algorithm; and

which Governikus seems not to fulfill.
