gpg: More diagnostics for a launched pinentry.

* agent/call-pinentry.c (start_pinentry): Call getinfo/ttyinfo.
* g10/server.c (gpg_proxy_pinentry_notify): Simplify the output so
that we do not change the code when adding new fields to
PINENTRY_LAUNCHED.
--

This patch changes the --verbose output of gpg to show
for example

  gpg: pinentry launched (5228 gtk2 1.0.1-beta10 \
  /dev/pts/4 xterm localhost:10.0)

the used tty, its type, and the value of DISPLAY in addiion to the
pid, flavor, and version.
