The rules for the command line parser are not cleary specified - if at

We can't use the mingw version because that would require to change
all argv handling to be wchar_t and that only for Windows. That would
be too ugly. Parsing the command line into argv by us is much easier
and we can do that only if needed - i.e. if globing is required (we
are prepared for this) or a non-ASCII character has been encountered.
This way we keep things stable and only fix the currently not working
Unicode problem.

but without changing all functions names to gpgrt. Instead we use
wrapper functions which, when building against old Libgpg-error
versions, are implemented in argparse.c using code from the current
libgpg-error. This allows to keep the dependency requirement at
libgpg-error 1.27 to support older distributions. Tested builds
against 1.27 and 1.40-beta.

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

Cherry-pick from master commit of:
50b02dba20
When gpg was invoked by a Perl web application on FreeBSD, fstat in
gnupg_reopen_std failed with EBADF. Using fcntl, which is considered
lighter than fstat, it works fine. Since uur purpose is to check if
file descriptor is valid or not, lighter operation is better.

Spawning minimized shows icons in the task bar so users

This fixes dirmngr_ldap process windows and other
spurious reports about e.g. a gpgv console window from
loadswdb.

This actually fixes a couple of cases for Windows. Both --home-dir

correct one but because we need an absolute dir anyway it is the less
surprising one. Note that this does not include a full syntax check
and fixup and thus it is very well possible that the result is not an
absolute directory.

This fixes a potential overflow if LFs are passed to the status
string functions. This is actually not the case and would be wrong
because neither the truncating in libassuan or our escaping is not the
Right Thing. In any case the functions need to be more robust and
comply to the promised interface. Thus the code has been factored out
to a helper function and N has been bumped up correctly and checked in
all cases.
For some uses this changes the behaviour in the error case (i.e. CR or
LF passed): It will now always be C-escaped and not passed to
libassuan which would truncate the line at the first LF.

--
Originally the KBX code was written to allow standalone use. However
this required lot of ugliness like separate memory allocators and
such. It also precludes the use of some standard functions from
common due to their use of the common gnupg malloc functions.
Dropping all that makes things easier. Minor disadvantages: the kbx
call done for gpg will now use gcry malloc fucntions and not the
standard malloc functions. This might be a bit slower but removing
them even fixes a possible bug in keybox_tmp_names which is used in
gpg and uses gpg's xfree which is actually gcry_free.

It was not the best idea to use constants from a planned libgpg-error

won't harm.
