Commit 91b826a388 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.

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.
* apdu.c (pcsc_keypad_verify): Have dummy Lc field with value 0.

* app-openpgp.c (do_change_pin): The flag use_keypad should be 0 when
reset_mode is on, or resetcode is on. use_keypad only makes sense for
iso7816_change_reference_data_kp.

Before this change, it is layered like following:
iso7816_verify
iso7816_verify_kp
apdu_send_simple, apdu_send_simple_kp
...
After this change, it will be layered like:
iso7816_verify iso7816_verify_kp
apdu_send_simple apdu_keypad_verify
...
and apdu_send_simple_kp will be deprecated.
For PC/SC API, we use:
SCardControl API to compose CCID PC_to_RDR_Secure message
SCardTransmit API to compose CCID PC_to_RDR_XfrBlock message
Considering the support of PC/SC, we have nothing to share between _kp
version of iso7816_* and no _kp version.
This patch implementes a chunk mode to pass the key parameters from
scdaemon to gpg. This allows to pass arbitrary long key paremeters;
it is used for keys larger than 3072 bit.
Note: the card key generation in gpg is currently broken. The keys
are generated but it is not possible to create the self-signature
because at that time the gpg-agent does not yet know about the new
keys and thus can't divert the sign request to the card. We either
need to run the learn command right after calling agent_scd_genkey or
implement a way to sign using the currently inserted card. Another
option would be to get rid of agent_scd_genkey and implement the
feature directly in agent_genkey.
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.
