---
This commit adds and plumbs in a tpm2daemon to the build to mirror the
operation of scdaemon. The architecture of the code is that
tpm2daemon.c itself is pretty much a clone of scd/scdaemon.c just with
updated function prefixes (this argues there could be some further
consolidation of the daemon handling code). Note that although this
commit causes the daemon to be built and installed, nothing actually
starts it or uses it yet.
Command handling
----------------
command.c is copied from the command handler in scd.c except that the
command implementation is now done in terms of tpm2 commands and the
wire protocol is far simpler. The tpm2daemon only responds to 4
commands
IMPORT: import a standard s-expression private key and export it to
TPM2 format. This conversion cannot be undone and the
private key now can *only* be used by the TPM2. To anyone
who gets hold of the private key now, it's just an
encrypted binary blob.
PKSIGN: create a signature from the tpm2 key. The TPM2 form private
key is retrieved by KEYDATA and the hash to be signed by
EXTRA. Note there is no hash specifier because the tpm2
tss deduces the hash type from the length of the EXTRA
data. This is actually a limitation of the tpm2 command
API and it will be interesting to see how this fares if the
tpm2 ever supports say sha3-256 hashes.
PKDECRYPT: decrypt (RSA case) or derive (ECC case) a symmetric key.
The tpm2 for private key is retrieved by KEYDATA and the
information used to create the symmetric key by EXTRA.
KILLTPM2D: stop the daemon
All the tpm2 primitives used by command.c are in tpm2.h and all the
tpm2 specific gunk is confined to tpm2.c, which is the only piece of
this that actually does calls into the tss library.

Changes from James' patch:
- gpgconf: The displayed name is "TPM" and not "TPM2". That
string is used by GUIs and should be something the user
understands. For example we also use "network" instead
of "Dirmngr".
- Removed some commented includes.
- Use 16 as emulation of GPG_ERR_SOURCE_TPM2.
- Silenced a C90 compiler warning and flags unused parameters.
- Removed "if HAVE_LIBS" from tpm2/Makefile.am and add missing
files so that make distcheck works.

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.

(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.

We need to do larger changes to gpgconf so that it is possible to get
also global config options and their attributes. The old code worked
along its own list of option and used a generic option file parser.
This has no support for global config files. We now use
gpgrt_argparser so that we to do exactly the same as the component
does and thus delivers the actual option values as seen by the
component.
This is just a first step and we need to change more things.

The order matters in a corner case; On a busy machine, there was a
race condition between gpg-agent's running KILLAGENT command and its
accepting incoming request on the socket. If a request by
gpg-connect-agent was accepted, it resulted an error by sudden
shutdown. This change of the order can remove such a race.
Here, we know backend=0 is none.

This is a convenience options for software which directly connects to

along with --launch that software can also autostart the agent or the
dirmngr. Without this two calls to gpgconf would be required.
Actually the same behaviour can be achieved by running
gpg-connect-agent to query the running gpg-agent's socket via GETINFO.
The gpg-connect also makes sure that the agent is started. This is
not anymore suggested because gpgconf shall in future be used for all
such things.
