16-bit PCMCIA device handling function definitions are moved to ds.h,
internal definitions to cs_internal.h.

Instead of using own error or success codes, the PCMCIA code should rely on
the generic return values. Therefore, replace all occurrences of CS_SUCCESS
with 0.

Remove the three remaining pcmcia_get_configuration_info() users:
- pcmciamtd is marked broken anyway.
- serial_cs.c can access the relevant structs directly
- ipwireless didn't use the output

ipwireless: Increase PPP outgoing queue size

Increase default size of PPP outgoing queue. Currently set to 1, which
means that a packet quickly following another pushed by PPP must wait
until hardware actually sends the previous and PPP has to be waken up
by ppp_wakeup(). This slows down upstream.

Now PPP can push more packets at once which get buffered inside driver
and pushed immediatelly to hardware when previous packet is out.

Experiments show that size = 10 is quite good for all connection types
(GPRS/EDGE/UMTS) and gains 4 KB/sec of upload for UMTS for batch uploads.
Need for higher queue size than 10 occures in only < 0.1 % of cases.

ipwireless: Explicitly request io and mem regions

Documentation/pcmcia/driver-changes.txt says, that driver should call request_region
for used memory/io regions since PCMCIA does not do this (since 2.6.8).

pcmcia/version.h is empty and its existence is not even needed by
deprecated userspace tools.

The device is manufactured by IPWireless.  In some countries (for
example Czech Republic, T-Mobile ISP) this card is shipped for service
called UMTS 4G.

It's a piece of PCMCIA "4G" UMTS PPP networking hardware that presents
itself as a serial character device (i.e.  looks like usual modem to
userspace, accepts AT commands, etc).
