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).

kbxutil is a debug tool but nevertheless it should behave well and not
read beyond allocated buffers and in turn crash.
Vincent Ulitzsch and Dominik Maier were kind enough to report these
crashes along with a couple of test keyboxes and crash analysis.

Commit 91b826a38880fd8a989318585eb502582636ddd8 was not enough to
avoid all sign extension on shift problems. Hanno Böck found a case
with an invalid read due to this problem. To fix that once and for
all almost all uses of "<< 24" and "<< 8" are changed by this patch to
use an inline function from host2net.h.

Without this fix a listing of all keys would fail because the wrong

To test this feature you may set the limit back to 1MiB and use key
F7F0E70F307D56ED which is in my local copy close to 2MiB. Without
this patch it was possible to import the key but access to that key
and all keys stored after it was not possible.

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.

The checksum was never used in the past. Due to fast SHA-1
computations in modern CPUs we now use SHA-1. Eventually we will
support a First blob flag to enable the use of a secret or public
HMAC-SHA1. The first may be used for authentication of keyblocks and
the latter to mitigate collission attacks on SHA-1. It is not clear
whether this will be useful at all.

The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems. We now use two \x27 characters ('...').
The proper solution would be to use the correct Unicode symmetric
quotes here. However this has the disadvantage that the system
requires Unicode support. We don't want that today. If Unicode is
available a generated po file can be used to output proper quotes. A
simple sed script like the one used for en@quote is sufficient to
change them.
The changes have been done by applying
sed -i "s/\`\([^'\`]*\)'/'\1'/g"
to most files and fixing obvious problems by hand. The msgid strings in
the po files were fixed with a similar command.
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.
