scd: Fix problem with reader list becoming empty.
* scd/apdu.c (close_pcsc_reader): Do not decrement refcount if already
zero.  Always release context if or becomes zero.
(apdu_dev_list_start): Unlock prior to close_pcsc_reader.  For PC/SC
increment the count.  Always release the lock.
(apdu_dev_list_finish): No more unlocking.  Use close_pcsc_reader
instead of code duplication.

* scd/apdu.c (pcsc_error_string): Add an error code.
* scd/scdaemon.c (scd_kick_the_loop): Fix a diagnostic.
--

There was an obvious bug in that the pcsc.count could go below zero
and thus there was no chance to get the context release.  Releasing
and recreating the context is at least under Windows important to get
rit of the PCSC_E_SERVICE_STOPPED.

Also removes a potential problem in holding the reader_table_lock
between calls to apdu_dev_list_start apdu_dev_list_finish.  There is
no need for this.  Instead we bump the pcsc.count.

The reader_table_lock strategy should be reviewed; we may be able to
remove it.

The do not cache property of 6E was introduced so that we can change

However, for initial reading the cache makes a lot of sense and thus we
now use this hack to only temporary cache.  A better strategy would be
to clear the cache when we change card data but that is more error

--

It appears that SP-800-73-x is not too clear about the format of these
objects. Many current cards (such as the Yubikey 5 series) apparently
have only the PIX in DO 0x4F and only the RID in object 0x79/0x4F.

However, other cards as well as the PivApplet Javacard applet have the
full AID in 0x4F (which actually seems closer to what the standard
says). PivApplet also has the full AID in 0x79/0x4F, but this is
probably incorrect. (Here is a long discussion of the matter from an
OpenSC author:
https://github.com/arekinath/PivApplet/issues/43#issuecomment-772649709)

This features allows to mark keys to be used for OpenPGP.  This is
done by putting additional extended key infos into the certificate
stored on the cards.  Only if any such extended key usage is detected
for a stored certificate this new mode chimes in.

This feature gives the card issuer a high flexibility on how to make
sure certain keys are used with OpenPGP.

This patch gets us back to a unique serial number for cards and
provides a stable serial number as printed for Yubikeys.

Because we use a slightly different serial number now for Yubikeys and
cards only supporting OpenPGP card we need to come up with another
change so that the version number of OpenPGP serial numbers are
ignored when comparing card serial numbers.  This is so that existing
stub keys of gpg-agent will continue to work.

(pcsc_vendor_specific_init): Send the ESC command for SPR532.

--

The "no_lc" hack lets PC/SC-lite send the ESC command for SPR532
internally, for pcsc_pinpad_verify.  However, PC/SC-lite doesn't do
that for pcsc_pinpad_modify, unfortunately.  Besides, I'm not sure
this hack works on Windows, which has different implementation of
PC/SC service.

It's better to send the ESC command by the driver explicitly, at the
initialization.  Sending the ESC command results PCSC_E_NOT_TRANSACTED
error when a card is not active (that is the case, usually).  We
ignore this error.

This can be used with gpg-card to write the 3 extra certificates of a
Telesec TCOS Signature Card v2.  The card with the qualified signature
is distributed with the keys for encryption and advanced signatures
but without the certificates.  The certificates can be downloaded from
the website after an mail confirmation.  Unpacked the downloaded
zipfile has these certificates:

  auth_zert.crt
  sig_zert.crt
  enc_zert.crt

Using gpg-card issue these commands:

 writecert NKS-NKS3.4531 <sig_zert.crt
 writecert NKS-NKS3.45B1 <enc_zert.crt
 writecert NKS-NKS3.4571 <auth_zert.crt

Don't mix that up, tight now there is no checking that the
certificates match the public key.  I also need to write another patch
to actually implement signing and encryption with these nistp256

scd: Fix Yubikey app switching problem
* scd/app.c (select_all_additional_applications_internal): Re-select

--

Usually keygrip based access to the Yubikey does a switching back and
forth and thus keeps the card and scdaemon's internal state in sync.
However, if we do only a listing scdaemon did not reselect the first
application (e.g. OpenPGP) after adding other applications (e.g. PIV)
and thus led to wrong info returned in a listing.

There is no need to read the list of options from the components
unless they convey a default value.  It is better to consult only the
list we have in gpgconf-comp.c to decide on whether an option should
be displayed.   Right, this might mess up thing if a newer gpgconf
version is used with an older component, but we already print warnings
in this case and in general we do not want to support this anymore -
the times of gpg 1.4. and 2.0 are long over now.

scd: Print the main app name also for not fully supported cards.
* scd/app.c (send_serialno_and_app_status): Add fallback.
--

The app list was only printed for apps which support the with_keygrip
function.  That is not the case for the netkey and otehr cards.  The
new fallback prints the actual app name.

scd:openpgp: Return key creation time as part of KEYPARIINFO.
* scd/app-openpgp.c (send_keypair_info): Reaturn the key creation time
as part of a KEYPAIRINFO.
(do_readkey): Do not return the KEY-TIME anymore.
--

Sending the KEY_TIME status as part of a READKEY command was only
recently added.  It is better to merge that into the KEYPAIRINFO line.
Another patch with chnage this for the consumers of that info.

scd:openpgp: Send a KEY-TIME status with READKEY
* scd/app-openpgp.c (retrieve_fprtime_from_card): New.
(do_readkey): Send a KEY_TIME status.
--

It might be easier to fold this into KEYPAIRINFO but for backward
compatibility using a separate status line is safer.

scd:openpgp: Optional allow for lowercase keyrefs.

keyref.

scd:openpgp: Allow auto-changing of the key attributes in genkey.
* scd/app-openpgp.c (struct app_local_s): Add field keyalgo.
(parse_algorithm_attribute): Store the new keyalgo field.
(change_keyattr): Change info message.
(change_keyattr_from_string): Rewrite to also accept a keyref and a
keyalgo string.
(do_genkey): Change the keyattr if a keyalgo string is given.
--

Having this feature makes it easier to use OpenPGP cards in a similar
way to other cards.  Note that the explicit changing via SETATTR is
still supported.

common: Extend the openpgp_curve_to_oid function.
* common/openpgp-oid.c (openpgp_curve_to_oid): Add optional arg R_NBITS.
Change all callers.

In particular for ed25519 and cv25519 it is quite useful to have an
ability to get the required algorithm.

build: Always use EXTERN_UNLESS_MAIN_MODULE pattern.
* common/util.h (EXTERN_UNLESS_MAIN_MODULE): Add the definion only
here but now without the Norcroft-C.  Change all other places where it
gets defined.
* common/iobuf.h (iobuf_debug_mode): Declare unconditionally as
extern.
* common/iobuf.c (iobuf_debug_mode): Define it here.
* agent/gpg-agent.c (INCLUDED_BY_MAIN_MODULE): Define here and also in
all main modules of all other programs.

* g10/main.h: Put util.h before the local header files.
--

This change is required for use with gcc/ld's LTO feature which does
not allow common blocks.  Further gcc 10 will make -fno-common the
default and thus this chnage is always needed.  What a pitty.

scd:openpgp: Let the genkey function also accept a full keyref.
* scd/app-openpgp.c (send_key_attr): Use log_assert.
(do_genkey): Allow prefix.
--

It is more uniform to always use full keyref (e.g. "OPENPGP.1")
instead of just the key number.
