Add a set of tests that exercise tpm2daemon handling of keys and
verify compatibility with non-tpm based keys.
Running this test infrastructure requires a tpm emulator, which is
tested for during configuration. If an emulator is not found, the
tests won't be run since they require the presence of a TPM (although
the TPM handling code will still be built).

---
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.

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.

This is a first try on a protocol to pair two devices so that they can
agree on a shared secret to exchange secret keys. The idea is that if
you want to sync your secret keys to another machine (e.g. from
desktop to mobile) you have physical access to both devices and thus a
pairing protocol allows to authenitcate the connection using a short
string. See the source for a protocol description.
How to test:
$ gpg-pair-tool -va --homedir . --initiate >msg.commit
$ gpg-pair-tool -va --homedir 2ndhome --respond \
<msg.commit >msg.dhpart1
$ gpg-pair-tool -va --homedir . --respond \
<msg.dhpart1 >msg.dhpart2
$ gpg-pair-tool -va --homedir 2ndhome --respond \
<msg.dhpart2 >msg.confirm
Now set the SAS as printed by the responder into SAS and run
$ gpg-pair-tool -va --homedir . --respond --sas $SAS <msg.confirm
Storing the secret on disk is obviously not the right thing to do.
With the new PUT_SECRET and GET_SECRET commands of gpg-agent we can
change this to store it all in gpg-agent instead. This will make it
also easier for gpg to access the secret and we won't need an option
to return it from gpg-pair-tool. Thus gpg-pair-tool can be dedicated
to run the protocol and maybe to popup info dialogs.
Adding a second expiration time for running the protocol in addition
to the expiration of the secret is probably a better idea than just
that simple catch-all TTL.
