---
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.

GnuPG-bug-id: 4398
We do not use this weirdo CREATE_UNICODE_ENVIRONMENT flag because it
does not make any sense to have non-ASCII names in the environment. I
can't imagine why this should be used at all and rationale for this
API features is, well, sparse.
* common/init.c (_init_common_subsystems) [W32]: Set the codepage to
UTF-8 for input and putput. Switch gettext to UTF-8.
* tools/gpgconf.c (main): Display the input and output codepage if
they differ.
* g10/gpg.c (utf8_strings) [W32]: Make sure this is always set.
--
With this patch the former patch to use ReadConsoleW and WriteConsoleW
in ttyio.c are kind of superfluous because the ANSI version of these
functions are also able to read/write UTF-8 directly given the console
code page has been set correctly. However, this seems to work only
with recent versions of Windows-10.

The rules for the command line parser are not cleary specified - if at
all. See the comment in t-w32-cmdline.c.
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.

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.

This is not yet finished but a make check works. gpg has the most
complex and oldest option handling and thus this is the first
migration target. SE-Linux checks and version-ed config files are
missing and will be added later.

This change is required for use with gcc/ld's LTO feature which does
not allow common blocks. Further gcc 10 will make -fno-common the
default and thus this chnage is always needed. What a pitty.

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
a few dozen of such strings (if at all) and thus all those allocations
we do internally in gpg's pubkey_string and the static buffers all
over the place are not too nice.

This change does away with encrypting and decrypting the cached PIN in
the agent. There is no need for this we can simply cache the
cryptogram and let scdaemon decrypt after retrieving it from the
agent. This way we do not need to share a key between gpg-agent and
scdaemon and further the cached content is invalid after the scdaemon
process has been replaced.

It turned out that using the hash of the entire blob was not helpful.
Thus we redefine the Unique-Blob-ID (UBID) as the primary fingerprint
of the blob. In case this is a v5 OpenPGP key a left truncated
version of the SHA-256 hash is used; in all other cases the full SHA-1
hash. Using a SHA-256 hash does not make sense because v4 keys are
and will for some time be the majority of keys and thus padding them
with zeroes won't make any difference. Even if fingerprint collisions
can eventually be created we will assume that the keys are bogus and
that it does not make sense to store its twin also in our key storage.
We can also easily extend the update code to detect a collision and
reject the update.

This code as a lot of rough edges, in particular it relies on a well
behaving keyboxd. We need to add code to shutdown the datastream
reader thread in case of errors and to properly get it up again. We
also need to make really sure that both threads run in lockstep so
that the datastream thread is only active while we are sending a
command to the keyboxd.
We should also see whether we can depend nPth initialization on the
--use-keyboxd option to avoid any problems with nPth.
And we need to test on Windows.
