Now that we have support for multiple tokens, it is important to show

later about entering a PIN.
A quick hack would be to s/passphrase/PIN/ in the description but that
is complicated due to i18n. Another solution might be never to talk
about PINs in the description but always about "passphrase: and only
use "PIN" or "passphrase" on the left of the entry field.

Previously, the function freed the last key, and duplicated the new

free if a different thread also calls this function.
To make sure the update is atomic under the non-preemptive thread
model, we must make sure not to surrender control to a different
thread. Therefore, we avoid calling the allocator during the
update.

During key generation Libgrypt will read from /dev/random which may

the progress callback. We detect this in gpg-agent and introduce a
short delay to give other threads (i.e. connections) an opportunity to
run.
This alone is not sufficient, an updated Libgpg-error is also required
to make the lock functions nPth aware.

"gpg-agent --supervised" is a way to invoke gpg-agent such that a

given a listening socket on incoming file descriptors.
* Does not detach from the invoking process, staying in the
foreground instead. Unless otherwise specified, logs are sent to
