This patch improves the BER parser by simplifying it. Now tlv_next
pops off and thus closes all containers regardless on whether they are
length bounded or ndef. tlv_set_pending is now always used to undo
the effect of a tlv_next in a loop condition which was terminated by a
nesting level change.
Instead of using the length as seen in the decrypted container we now
remove the padding and let the BER parser do its work. This might
have a negative effect on pkcs#12 objects which are not correctly
padded but we don't have any example of such broken objects.

This bug was exhibited by importing a gpgsm exported EC certificate.
We use an extra test instead of retrying to allow retruning an error
from malloc failure. And well, for easier reading of the code.

Over the last years we had a couple of changes not backported to 2.2.
However, to support DFN p12 files and probably other p12 files we need
to update the minip12.c module. Instead of picking commits we take
the module verbatim, which is relatively easy because it was
originally designed to be a standalone module.
Summary of commits taken from master:
sm: Improve pkcs#12 debug output.
sm: Rework the PKCS#12 parser to support DFN issued keys.
sm: Fix parsing encrypted data.
sm: Do not print certain issuer not found diags in quiet mode.
sm: Silence some output on --quiet
sm: Replace all assert calls by log_assert.
doc: Typo fixes in code comments
sm: Add support to export ECC private keys.

sm: Improve pkcs#12 debug output.

Fix offset diagnostic.
commit a4e04375e84ecb7ea0d02e153cb27988fca4c2d0
sm: Rework the PKCS#12 parser to support DFN issued keys.
* sm/minip12.c (struct p12_parse_ctx_s): New. Use this instead of
passing several parameters to most functions.
(parse_pag_data): Factor things out to ...
parse_shrouded_key_bag): new.
(parse_cert_bag): New.
(parse_bag_data): New.
(p12_parse): Setup the parse context.
To support newer pkcs#12 files like those issued by the DFN we
need to support another ordering of data elements. This rework
reflects the P12 data structure a bit better than our old ad-hoc
hacks. Tests could only be done with the certificate parts and
not the encrypted private keys.

* 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.

Added fix at a second place - wk.
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.
