[Muscle] ifd-egate version 0.90

[Jeffrey Hutzelman]

I've released version 0.90 of the egate driver, available at [1].

Since there have been no updates to this driver in a few years and this 
version contains a few significant changes, this is a sort of pre-release 
version.  It works for me, but hasn't been heavily tested under a wide 
range of conditions.  If you use egate devices (cryptoflex or cyberflex, 
using the egate USB interface rather than some other reader), please give 
it a try and let me know if you run into any problems.

My intent is to do a hopefully small number of these 0.9x releases and then 
eventually release a stable version 1.0.

New in this version:

- This version is updated to support version 3 of the pcsc-lite IFD
  handler API, and works without modification with current versions of
  pcsc-lite and pcscd.  It will also work with older versions, with
  some reduction in functionality.

- Support is added for hotplugging using libusb on platforms where it
  is available, or using libhal on Linux.  Note that when libusb is
  used, you must arrange for something to run 'pcscd --hotplug' any
  time a new egate device appears on the USB bus, or it will not be
  detected.  Alternately, run pcscd with --force-reader-polling to
  force pcscd to poll for readers.  This situation may be improved
  in a future release.

- The driver is now capable of supporting multiple egate devices at
  once.

- This version has an improved build system using GNU autoconf and
  related tools.
