* g10/getkey.c (merge_selfsigs_main): Take a zero key creation time in
account.
--
Keys created at the Epoch have a creation time of 0; when figuring out
the latest signature with properties to apply to a key the usual
comparison A > B does not work if A is always 0. We now special case
this for the expiration and usage data.

This is is the second part to support the new Key Block subpacket.
The idea is that after having received a signed mail, it is instantly
possible to reply encrypted - without the need for any centralized
infrastructure.
There is one case where this does not work: A signed mail is received
using a specified signer ID (e.g. using gpg --sender option) and the
key block with only that user ID is thus imported. The next time a
mail is received using the same key but with a different user ID; the
signatures checks out using the key imported the last time. However,
the new user id is not imported. Now when trying to reply to that
last mail, no key will be found. We need to see whether we can update
a key in such a case.

This patch adds support for a to be proposed OpenPGP ferature:
Introduce the Key Block subpacket to align OpenPGP with CMS.
This new subpacket may be used similar to the CertificateSet of
CMS (RFC-5652) and thus allows to start encrypted communication
after having received a signed message. In practice a stripped down
version of the key should be including having only the key material
and the self-signatures which are really useful and shall be used by
the recipient to reply encrypted.
#### Key Block
(1 octet with value 0, N octets of key data)
This subpacket MAY be used to convey key data along with a signature
of class 0x00, 0x01, or 0x02. It MUST contain the key used to create
the signature; either as the primary key or as a subkey. The key
SHOULD contain a primary or subkey capable of encryption and the
entire key must be a valid OpenPGP key including at least one User ID
packet and the corresponding self-signatures.
Implementations MUST ignore this subpacket if the first octet does not
have a value of zero or if the key data does not represent a valid
transferable public key.

* g10/verify.c (verify_files): Track the first error code.
--
It seems to be possible to play tricks with packet structures so that
log_error is not used for a bad input data. By actually checking the
return code and let the main driver in gpg call log_error, we can fix
this case.
Note that using gpg --verify-files and relying solely on gpg's return
code is at best a questionable strategy. It is for example impossible
to tell which data has been signed.

This build a wixlib of the Windows binaries of GnuPG.
A wixlib is a module that can be linked into another
wix project to create an installer including this
module. Gpg4win uses the wixlib from GnuPG for
it's MSI Package.
To build the wixlib you need wine with wine-mono installed
and the wixtoolset.
When calling speedo set the variable WIXPREFIX to
the location containing the extracted toolset.
e.g.:
make -f build-aux/speedo.mk w32-wixlib WIXPREFIX=~/wix

gpgsm --faked-system-time=XXXX --disable-crl-checks \

with XXXX being 20190230T000000 -> target cert too young
with XXXX being 20190330T000000 -> okay
with XXXX being 20190830T000000 -> okay, using the long term cert
with XXXX being 20220330T000000 -> target cert expired
The --disabled-crl-checks option is required because in our a simple
test setting dirmngr does not know about the faked time.

Bug is in 2.2.18 only.
The semantics of the enum_secret_keys function changed in master.
When back porting this for 2.2.18 I missed this change and thus we ran
into a double free. The patches fixes the regression but is it clumsy.
We need to change the enum_secret_keys interface to avoid such a
surprising behaviour; this needs to be done in master first.
