There is no need to read the list of options from the components
unless they convey a default value. It is better to consult only the
list we have in gpgconf-comp.c to decide on whether an option should
be displayed. Right, this might mess up thing if a newer gpgconf
version is used with an older component, but we already print warnings
in this case and in general we do not want to support this anymore -
the times of gpg 1.4. and 2.0 are long over now.

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.

Die to the switch to the new option parser, the permissions were not

checking for the global config file because that file is not expected
to be user modifiable.
This patch also adds checking against the list of SE-linux secured
files. However, like in the old code the checking does not work in
practise because the to be checked files are added to the the list
only after option parsing. Tested using temporary debug code.
The SAFE_VERSION macros were used for RISC OS, which is not anymore
supported, and only in the now removed get_default_configname. There
purpose was that a RISC OS could use a modified config.h here.

Key generation direct from the card used to work for all cards except
the OpenPGP cards. The key generation from card using an OpenPGP card
is special because the fingerprint is stored on the card and we must
make sure that the newly created key has the same fingerprint. This
requires that we take the key creation date as stored on the card into
account.
Along with the recent change in gpg-agent this change also fixes a
problem with existing stub files.
Note that with a key take from a card the self-signature are created
with the current time and not the creation time. This allows to
better distinguish keys created using the same card.

This function is intended as a more general version of gpg's
pubkey_string function. It has the advantage to avoid mallocs and
uses static table of algorithm strings instead. There should be only

we do internally in gpg's pubkey_string and the static buffers all
over the place are not too nice.
