pkcs11: no more 'hacked' mode and 'onepin' module version

'OnePIN' version of opensc-pkcs11 module is not installed.
Instead, in the 'pkcs11' section of OpenSC configuration,
there is a possibility to define in a different manner
how to create slots for the present PINs and applications.
pkcs11: prepare internal API for multi-application mode

- simplify some of framework handles: remove from it's prototype the arguments that can be derived from the other arguments;
for exemple: foo(slot, slot->card) --> foo(slot)
- add the 'application' argument to the bind, unbind and similar handles;
- preview more then one framework data attached to the pkcs11card object.
- placehold for the future 'derive' and 'can_do' handles.
pkcs15: new procedure to get application by it's symbolic name

At the moment symbolic names for the on-card applications are 'generic', 'protected'.
This distinction used by pkcs11 and minidriver module to select the
'master' application in the cases when only reduced number of slots (one)
can be exposed by module (minidriver) or particular configuration (pkcs11).
pkcs11: create tokens and slots for multiple on-card applications

In card detection procedure bind all present applications
and create tokens for them.

Treatement of the different 'create-slots' configuration cases,
joining the objects from different applications into one slot
are previewed for the next commits.
pkcs15: new procedure to find an Auth PKCS#15 object (PIN) by flags
pkcs15init: change sc_pkcs15init_bind() prototype

Add new argument 'application-info',
that will allow to select the on-card application to by binded with.

pkcs11: use sc_pkcs15init_bind with 'AID' argument

Prototype of sc_pkcs15init_bind() has been changed to add argument with
AID of the on-card application to be binded with.
pkcs15init: add 'minidriver-style' profile option

The on-card support of minidriver could need some MD specific pkcs#15 (DATA) objects.
There is no standard for these objects.
New option will allow to choose one of the possible implementations.
pkcs15init: syntax changed for the ias(ecc) profiles

improvements to opensc-explorer & new tool openpgp-tool

Usefull improvement: probably could be used in automated tests.

I follow Ludovic and attract your attention onto the necessity, in the nearest future, 
to supply the doc/man for the tool newly introduced.
Without it the build of OpenSC package will simply not be possible.
OpenPGP: correct PIN type to UTF-8

OpenPGP card spec v1.1 and v2.0 make it absolutely clear:
"... The format of the CHVs is UTF-8 (case sensitive) ...".

Determine length of prefix dynamically instead of using a hard-coded, common
value for all prefixes.
opensc-explorer: explicitly mention key types
opensc-explorer: use case-insensitive pin types in PACE
opensc-explorer: update documentation
OpenPGP: extend openpgp-tool
OpenPGP: documentation for openpgp-tool
tools: allow arguments to be printed in usage message
