future proofing linux-2.6 config, disabling deprecated interfaces

[maximilian attems <max@stro.at>]

for 2.6.29 following interfaces will be unset:
- SCSI_PROC_FS
  should only be needed by legacy apps, sysfs equiv exists

- PCMCIA_IOCTL
  pcmciautils is even already shipped in etch

- ACPI_PROCFS
- ACPI_PROCFS_POWER
- ACPI_PROC_EVENT
  scheduled to be removed soon

they should only be needed by legacy applications
and it is the right time in the release now to either
have those kicked out as nobody uses them anyway or
to have userland fixed.

if the outcry is too big again on the acpi interfaces
like it happened for lenny we can go back and wait until
upstream anyway decides for us and those disappear under
our feet. but maybe userland got ready in between.

anyway i think it is a good plan now to start making aware userland,
unless objections, i'll set those next week. if i omitted an
important item out of feature-removal-schedule.txt please
point that out too.

kind regards
