In floppy controller, transfer data len is not correctly calculated.
We should read up to the last sector specified by the caller, and not up to
the last sector of the floppy.

In floppy controller, programming PIO writes which are more than one sector
long leads to a buffer overflow of the fdtrl->fifo[] array.

- Replaces access to cur_drv field by macros.

- Supports up to 4 floppy drives if MAX_FD is set to 4.

- Replaces bootsel field by the whole tdr register. It may be easier if we want to later add support for tapes.

- Removes useless fields in fdrive_t structure.
- Adds a message when bdrv_read/bdrv_write calls fail.
- Rename int_status to status0.
- Replace some constants by value names.

- Stores controller state in MSR register instead of internal state field. This simplifies the fdctrl_read_main_status() function, which may be called in some tight loops.

- Better handling of DOR register. DOR register drives external motors, but it not limited to existing drives.
- Use FD_DOR_nRESET flag instead of internal FD_CTRL_RESET flag.
- Support writing to DOR register even in reset mode (as said in specification)

- Handles correctly FD_MSR_NONDMA/FD_DOR_NONDMA flags, and uses them when possible. Fixes a problem with SPECIFY command.

- Fixes status A and status B registers. It removes one Sun4m mutation. Also removes the internal FD_CTRL_INTR flag.

- Extract seeking to next sector handling in a function. Add a sector seek in PIO read and write modes

- Adds a command lookup table, as suggested by Fabrice at http://lists.gnu.org/archive/html/qemu-devel/2008-04/msg00143.html
- This also moves initialization functions at the bottom of the file to prevent multiple forward declarations.

  nb_sectors instead of len in bytes but the fdc driver has never been fixed.
