Using "lookup" also for key search debugging was not a good idea.

Replace most of the remaining stdio calls by estream calls.
--

We need to use es_fopen on Windows to cope with non-ascii file names.
This is quite a large but fortunately straightforward change.  At a
very few places we keep using stdio (for example due to the use of
popen).

The data specific part of the code has been moved from gpg to a new
module in kbx/ so that it can also be used by gpgsm.  The OpenPGP
parsing while reading the data has been replaced by storing the data
in memory and parse it later.  That makes a nice interface and
abstracts the fd-passing/D-lines handling away.

--

It turned out that using the hash of the entire blob was not helpful.
Thus we redefine the Unique-Blob-ID (UBID) as the primary fingerprint
of the blob.  In case this is a v5 OpenPGP key a left truncated
version of the SHA-256 hash is used; in all other cases the full SHA-1
hash.  Using a SHA-256 hash does not make sense because v4 keys are
and will for some time be the majority of keys and thus padding them
with zeroes won't make any difference.  Even if fingerprint collisions
can eventually be created we will assume that the keys are bogus and
that it does not make sense to store its twin also in our key storage.
We can also easily extend the update code to detect a collision and
reject the update.

That change is straightforward.  It helps to avoid the race condition

--

This patch introduced the framework to store meta data for keys and
user ids in the keyrings/keyboxes.  Ring trust packets are
implementation defined and have always been used in gpg to cache the
signature verification status.

Ring trust packets are only exported with the export option "backup"
and only imported with the import option "restore".

The new code uses a cleaner way to handle the ring trust packets: When
the parser reads a ring trust packet and the previously read packet
matches the type of that ring trust packet, the information is stored
in that previously read packet (signature, user id, or primary key)
and the next packet is read immediately.  Thus only the parser sees
the ring trust packets.  Ring trust packets are written by using the
new function build_packet_and_meta instead of build_packet.  That
function writes a ring trust packet when the needed information is
available.

As a side-effect of this patch the signature status cache works again
and "gpg --check-sigs" is thus much faster.

We now store the computed policy in the tofu DB (in the
effective_policy column of the bindings table) to avoid computing it
every time, which is expensive.  Further, policy is never overridden
in case of a conflict.  Instead, we detect a conflict if CONFLICT is
not empty.

This change is backwards compatible to existing DBs.  The only minor
incompatibility is that unresolved conflicts won't be automatically
resolved in case we import a direct signature, or cross signatures.

This change aligns the registering of keyboxes with those of
keyrings.  This fixes a potential bug:

  gpg --keyring foo.kbx --keyring bar.gpg --keyring foo.kbx

would have marked bar.gpg as primary resource and thus inserting new
keys there.  The correct and now fixed behavior is to insert to
foo.kbx.

When using tags (e.g. GNU global) to navigate the source code it is

GnuPG-bug-id: 2193

Between locating the record to update and actually updating the
keyblock, it is possible that another process modifies the keyring,
which causes the update to corrupt the keyring.  This is due to a time
of check to time of use bug.  The fix is straightforward: both
operations must be done while holding the lock.  This changes the
semantics of the function slightly, but no callers need to be
modified.  Further, it now becomes impossible to replace key A with B;
this function will only ever update B.
