Requests the passphrase with a popup.
As from GPGME 1.15.0, the loopback pinentry is functional when exporting secret keys. It works fine when the exact passphrase is provided. If it's a wrong passphrase, GPGME does not generate an ::Error, but the app crashes with 'free(): double free detected in tcache 2'.
Hence, this patch cannot be committed to master.
Status : dangerous
Result : works and works not
Reason : a wrong passphrase means a crash
The email parameter must have a valid email address format here, else
GPGME will refuse to create the identity. This is not the case when
creating a key, where any string is accepted.
Correct format :
name <email> (comment)
Was :
name <email> comment
Though the 'comment' part was visible with the cli gpg app, it was not
shown in kleopatra and in K7.
Result : fails.
Reason : loopback passphrase provider is never called.
With default pinentry mode, the passphrase is requested normally
and the private key is exported. But this can't be done on a web server.
Enclosed in #ifdef DEVTIME.

Created key must always be looked for as it is not assigned to the
passed in null key.
Delete local context and loopback passphrase provider.
Parameter expires was ignored in CreateKeyWithEngineDefaultAlgo.
This is a trade-off.
When the calendar of the WDateEdit is clicked, widget PopupExpiryTime gets hidden, forcing to show it again.
If PopupExpiryTime::setTransient is false, it will obviously persist, until explicitly hidden with the Close button. Not satisfactory to change key selection while it is visible, nor to do other tasks like changing certification trust level, certifying uids.... whatever.
Forcing its persistence while playing with many events has not been successful, and quite ugly.
A private key should be editable to Unknown or Ultimate levels only.
A public key should be editable to all levels except Ultimate.
Undefined level is excluded for both public and private keys.
The public WTreeTableNode may list private keys if the user does not manage
these private keys. Inform of this state in the tool tip. The certification
trust level is excluded for any change.
