Actually, initialize_module_call_pinentry is only called once from
main. So, this bug had no harm and having the static variable
INITIALIZED is not needed.

We use the member PINENTRY_ACTIVE as a thread private object.
It's only valid for a single thread at a time.
It would be possible to have a thread shared object of
PINENTRY_ACTIVE, keeping ENTRY_OWNER for distinguishing its
owner (which is also a thread shared object). But, in this case,
access to ENTRY_OWNER is tricky (only comparison to accessing thread
would be OK with no lock), or we need to introduce another lock for
accessing ENTRY_OWNER, which complicates the code too much.
So, simply have a thread private object for recursive pinentry access.

Static strings in gpg-agent need to be translated according to the
locale set by the caller. This is required so that a gpg-agent can be
started in one locale and a gpg can be run in another. If we don't do
this the static strings (prompt, buttons) are not or in the wrong
locale translated while dynamic strings (e.g. key description) uses
the locale of gpg.
This is only the first part of the change the actual local switching
still needs to be implemented.

The idea with this change is that under Windows we can install a
simple native Windows pinentry as "pinentry-basic" and a full GUI
version may then later install pinentry-gtk etc which would then
automatically be used.
Unfortunately installing another pinentry from a different package
would clobber the GnuPG core directory which is not nice. To fix that
we would need to agree on standard installation directories for GUIs
to also look there.

If we need to confirm a passphrase entry (e.g. for new passphrase) we
set a flag into the pinentry info block. The we try to use the new
pinentry command SETREPEATERROR; if that fails, we continue as usual.
If that succeeds we ask the pinentry to show the repeat (confirmation)
prompt and on successful return we set another flag in the pinentry
info block so that the caller can skip its own confirmation check. A
new status line from the pinentry indicates that the feature is
actually supported (it may not be supported on certain systems for
example when using the ncurses backend).

The gpg server mode is not actual working and thus we can avoid the
