Yes, I know that there is a lot of code duplication. In fact some of
the code is ugly and it would be better if we enhance Libgcrypt to
guarantee that returned memory buffers via gcry_sexp_extract_param are
allways Nul terminated and we should also enhance that function to
directly extract into an unsigned int or char *.

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.

(gc_component_id_t): this.
(GC_COMPONENT_ANY): New, so that we can use that in gpgconf-comp.c
directly.
* tools/gpgconf-comp.c: Major rework.
--
The primary reason for this rework is to support the global options.
A second reason is to clean up the code and simplify it so that we do
not anymore need to maintain a list of options in the components _and_
in gpgconf-comp.c.
What we do now is to
1. Read the option tables directly from the components using
the new generic --dump-option-table option. This includes
the header (group) descriptions.
2. Read the default values from the components as before using
--gpgconf-list and update gpgconf's internal tables with
that info.
3. Read the options using gpgrt_argparser in the same way as we do
this in the components.
The changes also do away with the second level notion of backends;
they were only used for dirmngr's extra dirmngr_ldapservers.conf file.
We intend to remove that file and replace it with a regular option so
that it will be similar on how OpenPGP keyservers are specified.
The whole thing will currently be slower than before (in particular on
Windows) but we can optimize that by keeping a cached version of the
option tables and the default values in a per homedir cache file.
There is also some work planned to remove most of the data returned by
--gpgconf-list. What can also be done is to replace the internal
tables, which list the gpgconf maintainable options, by a configuration
file so that admins are able to maintain the list of these options.
