A simple gpg --check-sigs benchmark showed on Linux a small

system size).

Running a test on Windows using a pubring.kbx with
Total number of blobs: 2098
openpgp: 1294
x509: 803
and a size of 42MiB with
gpgsm -k --with-validation --disable-dirmngr --kbx-buffer-size N >nul
gives these performance figures using procmon
| N(k) | file events | time(s) |
|------+-------------+---------|
| 0 | 4900000 | 86 |
| 16 | 2456000 | 58 |

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.

(KEYBOX_LL_OPEN_UPDATE, KEYBOX_LL_OPEN_CREATE): New.
* kbx/keybox-init.c (_keybox_ll_open): New. Replace all keybox use of
es_fopen by this function.
(_keybox_ll_close): New. Replace all keybox use of es_fclose by this
function.

Note that this has not been done for the utilities and the backend-kbx
of keyboxd.

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).

Also use SHGetFolderPathW instead of SHGetFolderPathA on Windows.

another handle.

* kbx/keybox-init.c (keybox_lock): New arg TIMEOUT. Change all
callers to pass -1 when locking.
* sm/keydb.c (struct resource_item): Remove LOCKANDLE.
(struct keydb_handle): Add KEEP_LOCK.
(keydb_add_resource): Use keybox locking instead of a separate dotlock
for testing whether we can run a compress.
(keydb_release): Reset KEEP_LOCK.
(keydb_lock): Set KEEP_LOCK.
(unlock_all): Take care of KEEP_LOCK.
(lock_all): Use keybox_lock instead of dotlock fucntions.
(keydb_delete): Remove arg UNLOCK.
* sm/delete.c (delete_one): Adjust keydb_delete. Due to the KEEP_LOCK
the keydb_release takes care of unlocking.

This aligns the code more with g10/keydb.c and avoids the separate
calls to dotlock_take.

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.

The problem was reported by dkg on gnupg-devel (2014-10-07):
I just discovered a new problem, though, which will affect people on
systems that have gpg and gpg2 coinstalled:
0) create a new keyring with gpg2, and use it exclusively with gpg2
for a while.
1) somehow (accidentally?) use gpg (1.4.x) again -- this creates
~/.gnupg/pubring.gpg
2) future runs of gpg2 now only look at pubring.gpg and ignore
pubring.kbx -- the keys you had accumulated in the keybox are no
longer listed in the output of gpg2 --list-keys
Note that gpgsm has always used pubring.kbx and thus this file might
already be there but without gpg ever inserted a key. The new flag in
the KBX header gives us an indication whether a KBX file has ever been
written by gpg >= 2.1. If that is the case we will use it instead of
the default pubring.gpg.

I did most of these changes back in 2011 and only cleaned them up
now. More to follow soon.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
