kbx: For non-Windows use 64k buffers by default instead of 128k.
* kbx/keybox-init.c (DEFAULT_LL_BUFFER_SIZE): New.
--

A simple gpg --check-sigs benchmark showed on Linux a small
performance peak at around 64k (5m52 vs. 6m8 for 128k and 6m33 for
system size).

Using _open instead of CreateFile give the same number of file events
but increased the time slight by one second for the measured buffer
size of 64k and 128k.   Benchmarks for gpg have not been conducted.

Under Windows "sysopen" requests that direct API calls (CreateFile et
al.) are used instead of the libc wrappers.  This may or may not
improve the performance.

Using "sequential" is a hint to Windows to assume that a file is in
general access in a sequential manner.  This will have an affect only
with a future libgpg-error.

commit 0e8f6e2aa98c212442001036fb5178cd6cd8af59

but without changing all functions names to gpgrt.  Instead we use
wrapper functions which, when building against old Libgpg-error
versions, are implemented in argparse.c using code from the current
libgpg-error.  This allows to keep the dependency requirement at
libgpg-error 1.27 to support older distributions.  Tested builds
against 1.27 and 1.40-beta.

Note that g13-syshelp does not anymore default to --verbose because
that can now be enabled in /etc/gnupg/g13-syshelp.conf.

w32: Support Unicode also for config files etc.
* common/sysutils.c (gnupg_fopen) [W32]: Use _wfopen if needed.   Use
new function in most places where fopen is used.
--

The config files in 2.2 are still read using fopen - we need to change
this to allow Unicode directory names.  There is also one case where
files are written using the old fopen.  The new option parser in 2.3
does not have this problem but at some places fopen is also still used.

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

kbxutil is a debug tool but nevertheless it should behave well and not

This has been marked for too long as not yet working.  However, it is

all keys matching one keygrip.

Can be optimized a lot by storing the keygrip in the meta data.  This
will be done along with the upgrade of KBX for v5 fingerprints.

On most 32 bit systems size_t is 32 bit and thus the check

  size_t cert_off = get32 (buffer+8);
  size_t cert_len = get32 (buffer+12);
  if (cert_off+cert_len > length)
    return gpg_error (GPG_ERR_TOO_SHORT);

does not work as intended for all supplied values.  The simplest
solution here is to cast them to 64 bit.

In general it will be better to avoid size_t at all and work with
uint64_t.  We did not do this in the past because uint64_t was not
universally available.

Originally the KBX code was written to allow standalone use.  However
this required lot of ugliness like separate memory allocators and
such.  It also precludes the use of some standard functions from
common due to their use of the common gnupg malloc functions.
Dropping all that makes things easier.  Minor disadvantages: the kbx
call done for gpg will now use gcry malloc fucntions and not the
standard malloc functions.  This might be a bit slower but removing
them even fixes a possible bug in keybox_tmp_names which is used in
gpg and uses gpg's xfree which is actually gcry_free.

Some invocations of log_set_prefix() were done with raw numeric values
instead of values that humans can understand.  Use symbolic
representations instead of numeric for better readability.

* common/init.c (init_common_subsystems): Initialize libgcrypt.
* dirmngr/Makefile.am (dirmngr_ldap): Link with libgcrypt.

--
Most other modules already call gcry_check_version() after
init_common_subsystems() so may as well move initialization of libgcrypt
to here. Also fixes a warning in the system log from gpgconf --homedir.

kbx,w32: Use shorter retry intervals for keybox_file_rename.
* kbx/keybox-util.c (keybox_file_rename): Restart retry intervals
after 800ms.
--

The common use case is that the process waiting for a rename does an
import while another process does a key listing with only short lock
periods.  Thus it does not make sense to set the final backoff time to
8s.  It would actually be okay to retry every 100ms but that would
spill the console with "waiting..." messages.  This change prints the
waiting message only every 1.5s.

--

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.
