* agent/call-daemon.c (wait_child_thread): Print the correct name.

This makes sure that the log print the actual used name if for example
--pinentry-program was used.

---
A new shadow key type: "tpm2-v1" is introduced signalling that the
shadowed key is handled by the tpm2daemon. A function to identify
this type is introduced and diversions to the tpm2daemon functions are
conditioned on this function for pkign and pkdecrypt where the same
diversions to scd are currently done. The (info) field of the
shadowed key stores the actual TPM key. The TPM key is encrypted so
only the physical TPM it was created on can read it (so no special
protection is required for the info filed), but if the (info) field
becomes corrupt or damaged, the key will be lost (unlike the token
case, where the key is actually moved inside the token).
Note, this commit adds handling for existing TPM format shadow keys,
but there is still no way to create them.

* agent/call-daemon.c (struct wait_child_thread_parm_s) [W32]: Do not
use HANDLE for pid_t.
(wait_child_thread): Ditto.
--
Mingw has its own definition of pid_t as does libassuan. We should use
this instead of using HANDLE. Things are a bit complicated in
Windows, because Windows also has a pid_t but that is mostly useless;
in particular because you can't wait on a real pid but need a handle.

* agent/call-scd.c: Factor re-usable code out to ...
* agent/call-daemon.c: new. Store infos in an array to allow for
other backend daemons.
* agent/Makefile.am (gpg_agent_SOURCES): Add new file.
* agent/agent.h: Include assuan.h.
(enum daemon_type): New.
(opt): Replace scdaemon_program by daemon_program array. Replace
scd_local by a array d_local. Change users accordingly.
--
The model I'm using for a TPM daemon is the current scdaemon. That
includes start and stop handlers plus liveness checks and an assuan
socket generator. To avoid massive code duplication (and save me a
lot of effort), I've elected to strip this code out of call-scd.c into
a generic framework which can then be reused as is by the TPM handling
daemon.
