Commit message from 2.4:
Running a test on Windows using a pubring.kbx with

openpgp: 1294

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 |

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.

es_fopen by this function.

We need to make sure that there are no open files on Windows. Thus we
close them at several strategic locations.

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.
This is required to correctly handle non-ascii filenames on Windows.

Note that here in the 2.2 branch the way we call the locking in gpgsm
is different from the one in gpg. So we could not cherry-pick from
master.

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.
