OpenSSH has transitioned from using MD5 to compute key fingerprints to
SHA256. This patch makes the digest used when communicating key
fingerprints to the user (e.g. in pinentry dialogs) configurable.
For now this patch conservatively defaults to MD5.

During key generation Libgrypt will read from /dev/random which may
block. Libgcrypt is not nPth aware and thus the entire process will
block. Fortunately there is also a select with a short timeout to run
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.

There were several different variant spellings of "passphrase". This

I did notice that po/it.po contains multiple instances of

When removing not a simple socket file but the entire directory the
old code missed most events and thus did not worked properly.
IN_DELETE_SELF has also been added to the watch list to detect a
removal of the directory. However, in all tests that event was not
triggered. The only way it could be triggered was by not watching
the socket dir but an arbitary directory and rmdir that.

--
"gpg-agent --supervised" is a way to invoke gpg-agent such that a
system supervisor like systemd can provide socket-activated startup,
log management, and scheduled shutdown.
When running in this mode, gpg-agent:
* Does not open its own listening socket; rather, it expects to be
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
stderr.

It is simply the best for nPth not to allow the daemonizing fork after

This change enables the restricted, browser, and ssh socket by

this should not break any existing setups, but makes it simpler to

--
If a [/var]/run/user/$(id -u)/ directory exists, a gnupg subdir is
created as needed and the permissions of the directories are checked.
If that all matches that directory name is returned instead of the
homedir.
To cope with non standard homedirs (via GNUPGHOME or --homedir) the
SHA-1 hash of the homedir is computed, left truncated to 120 bits,
zBase-32 encoded, prefixed with "d.", and appended to
"[/var]/run/user/$(id -u)/gnupg/". If that directory exists and has
proper permissions it is returned as socket dir - if not the homedir
is used. Due to cleanup issues, this directory will not be
auto-created but needs to be created by the user in advance.
The required permissions are: directory owned by the user, group and
others bits not set.
