Teach the debug logging macro to differentiate between log levels based on the
type of debug level enabled specifically instead of a threshold-based one.
Thus, convert tape->debug_level to a bitmask that is written to over /proc.

Also,
- cleanup and simplify the debug macro thus removing a lot of code lines,
- get rid of unused debug levels,
- adjust the loglevel at several places where it was simply missing (e.g.
  idetape_chrdev_open())
- move the tape ptr initialization up in idetape_chrdev_open() so that we can
  use it in the debug_log macro earlier in the function.

The commit 139ddfca ("ide: move handling of
I/O resources out of ide_probe_port()") changed the ordering of hwif->noprobe
check vs ide_hwif_request_regions() call (so that we now reserve I/O regions
before checking for hwif->noprobe).  However ide-generic host driver depended
on hwif->noprobe to be set for skipping probing of empty ide_hwifs[] slots.

Fix it by passing only indexes of non-empty slots to ide_device_add_all()
from ide_generic_init().

Redo the calculation of NR_syscalls since that disappeared from i386 and
use a similar mechanism on x86_64.

We now figure out the size of the system call table in arch code and stick
that in syscall_table_size.  arch/um/kernel/skas/syscall.c defines
NR_syscalls in terms of that since its the only thing that needs to know
how many system calls there are.

The old mechananism that was used on x86_64 is gone.

arch/um/include/sysdep-i386/syscalls.h got some formatting since I was
looking at it.
