    Brings back SamsungRIL

Fix support for CDMA devices in SamsungRIL.

These fixes are ported from jt1134's fascinatemtd patches and CM7.  For
CM9, the fixes are applied to SamsungRIL directly instead of elsewhere in
the telephony framework.  They include:

- Signal strength reporting: pass raw integer values.
- Voice registration: convert base station values from hex to dec.
- Data call setup/deactivate: start/stop pppd_cdma service and pull network
  parameters from pppd ip-up script.
- CDMA subscription: add missing PRL version from system properties.

Changes from CM7:

Note use of "ril.cdma.data_state" property instead of
"ril.cdma.data_ready".  This property has three states:

- Disconnect(ed): ril.cdma.data_state=0: stop pppd_cdma service.
- Connecting:     ril.cdma.data_state=1: (re)start pppd_cdma.
- Connected:      ril.cdma.data_state=2: pppd_cdma has responded.

The disconnect (0) and connecting (1) states are set by SamsungRIL on the
deactivation and setup, respectively, of a data call.  Prior to setting the
connecting (1) state, SamsungRIL sets the "net.cdma.datalinkinterface" for
pppd_runner's use.

After setting to the connecting (1) state, SamsungRIL waits for pppd_cdma
to respond by (itself) setting the connected (2) state.  This should be
done at the end of a /system/etc/ppp/ip-up script, after that script sets
the following interface values, which SamsungRIL uses to complete the data
call state:

- net.cdma.ppp.interface: $IFNAME (typically "ppp0")
- net.$IFNAME.local-ip:   pppd's local IPv4 address
- net.$IFNAME.remote-ip:  pppd's remote IPv4 address
- net.$IFNAME.dns1:       pppd's primary DNS address
- net.$IFNAME.dns2:       pppd's secondary DNS address

Telephony: Add "singlepdp" RIL feature

ICS appears to assume the radio implementation is capable of multiple
simultaneous PDP contexts; maguro, for instance, brings up a second
interface (rmnet1) alongside the primary rmnet0 whenever another APN
is needed.
Other devices (including, from tests, crespo) don't accept this, and
react in unpredictable ways when a SETUP_DATA_CALL request is made before
tearing down any other active context (making it impossible, or at
least hard, to switch APNs).

Since the old setup/deactivateDefaultPDP methods are gone, this patch
adds a back-compatibility "singlepdp" option to the ro.telephony.ril.v3
property, which enforces disabling the default PDP whenever another one
is enabled.

Add more CDMA SamsungRIL fixes.

Adds a collection of CDMA device fixes to SamsungRIL.  They include:

- Overriding ERROR_UNSPECIFIED fail cause with NORMAL_CLEARING, to prevent
  far-end hangups from displaying the "Call Lost" dialog.

- Adding, and ignoring the RIL_UNSOL_GPS_NOTI request, which is also
  ignored in the TW RIL, to keep the radio log clean of exceptions when the
  GPS is active.

- Workaround for Samsung CDMA "ring of death" bug.  See source comments for
  details on this problem.

SamsungRIL: Fixes for CDMA data reconnection failures due to stale pppd

Occasionally the CDMA data connection fails to reconnect after various
radio events, which is fixed neither by toggling mobile data nor airplane
mode, but only by a reboot.  One known cause of this problem is that the
pppd_cdma service is occasionally left running after the radio event, which
causes all subsequent "setup data call" operations to fail.  These two
fixes address the stale pppd_cdma service issue:

- Move the pppd_cdma service shutdown (set ril.cdma.data_state=0) from the
  "deactivate data call" response to its request.  This avoids the issue
  where the response never comes (radio crash?), and thus, the service is
  never stopped.

- Force pppd_cdma service shutdown on a "setup data call" failure.  This
  allows subsequent setup attempts to succeed in the event that the
  "deactivate" request was never made (unexpected radio poweroff).
SemcRIL: Update for SEMC RILv6

This updates SemcRIL for v6, right now we are taking advantage
of the higher visibility on RIL.java and overloading the required
components instead of reimplementing processSolicited/unsolicited.

The same technique can be used in QualcommNoSimReadyRil, but I'd
rather do this more contained test first.
