Changeset 3506 for trunk/src/libopensc/opensc.h

Message:

Plug&Play support

This is not the best solution, but focus on smallest code change.

Changes:

1. Add detect_readers() to reader opts, this adds new readers to the end

of the readers list until list is full.

2. Add sc_ctx_detect_readers() that calls readers' detect_readers().

3. Fixup pcsc_lock() so that it reconnect to the card and report proper

error so caller may be notified if session was lost.

4. Allow context to be created without readers.

5. Call sc_ctx_detect_readers() from PKCS#11 C_GetSlotList with NULL_PTR.

6. Allow no reader at detect_card, as reader my be removed.

7. Since I broke ABI, I updated the external module version requirement

to match OpenSC version. In the future a separate version should be
maintained for each interface, this should be unrelated to the package
version.
