common,w32: Remove duplicated backslashes when setting the homedir.
* common/homedir.c (copy_dir_with_fixup) [W32]: Fold double
backslashes.
--

This is in general no problem but when we hash or compare the directory
to test whether tit is the standard home directory, we may use a
different socket file and thus a second instance of a daemon.

* agent/findkey.c (agent_write_private_key): Update only if modified.
--

This helps software which uses a file system watcher to track changes
to private keys.  In particular smartcard triggered changes are a
problem for such software because this may at worst trigger another
smartcard read.

common: Improve lock strategy for dotlock.
* common/dotlock.c (next_wait_interval): New.
(dotlock_take_unix): Use new function.
(dotlock_take_w32): Ditto.
--

In particular when using a dotlock file for protecting the spawning
and several processes try to spawn the agent or another component, we
often run into long delays.  The solution is to is to exponential
backoff and also to reduce the initial delay from 50ms to 4ms.  We
further limit the maximum wait period to about 2 seconds and then
repeat at intervals of 512, 1024 and 2048ms.  In the wait-forever case
we add a small random value to have different intervals per process.

GnuPG-bug-id: 3380

For testing this code snippet in the spawning function might be
useful:

          const char *s;
          if ((s=getenv("hold_gpg_file")))
            while (!gnupg_access (s, F_OK))
              gnupg_sleep (1);

License change of the test module justified because I am the single

for the feature is PDF signature checking where the PDF specs require
that the detached signature is padded with zeroes.

The introduction of --override-compliance-check actually hid the real

This function is intended as a more general version of gpg's
pubkey_string function.  It has the advantage to avoid mallocs and
uses static table of algorithm strings instead.  There should be only
a few dozen of such strings (if at all) and thus all those allocations
we do internally in gpg's pubkey_string and the static buffers all
over the place are not too nice.

This extends the long available OCB and EAX decryption feature.  Due
to the meanwhile expired patent on OCB there is no more reason for
using EAX.  Thus we forcefully use OCB if the AEAD feature flag is set

In GNUPG mode new keys are now created with the AEAD feature flag set.
Option --rfc4880 is one way to disable this.
