When turning on/off SoftAp with high frequency, sometime calling
WifiManager#updateInterfaceIpState with IFACE_IP_MODE_TETHERED
is performed after handling WIFI_AP_STATE_DISABLED event in
WifiServiceImpl while SoftAp is being terminated. This leads to
the issue that SoftAp is unable to start as startSoftAp always
returns "false". This is because mIfaceIpModes in WifiServiceImpl
keeps the mode WifiManager.IFACE_IP_MODE_TETHERED and the CL below
rejects SoftAp start request.

e257c5c9e79e3675375ca20731cfb74df02b1064 @ frameworks/opt/net/wifi
(WifiServiceImpl: Reject startSoftAp when already tethering)

This CL updates the interface ip state upon receiving ap disable
event from Tethering class to set proper state to mIfaceIpModes.

There are non-app process usecases in framework code that need to have
access to this API.
Created a new package android.compat in frameworks/base/core following
previous definition of android.compat.Compatibility for app processes
(http://cs/android/libcore/luni/src/main/java/android/compat/Compatibility.java).

Move Half FP16 implementations to libcore, to allow ART compiler to
optimize these methods with intrinsic implementations.

For example, on ARM64 with ARMv8.2 FP16 half registers and instructions:
- Half toFloat/toHalf can be implemented with FCVT;
- Half floor/ceil/round can be implmented with FRINT(pna);
- Half max/min can be implmented with FMIN/FMAX.

Such fast Half FP16 intrinsics can help accelerate ColorLong ARGB
encoding/decoding in Android framework.

The resource loading is done based on the last SIM to come up
which is not a deterministic design. Thus, update the way to get
the resource based on the subId.

There looks to be a case where infinite recursion
is occuring when printing information about
Telecom Sessions. Set a reasonable limit of
iterations and throw a warning when this condition
occurs to better track down a root cause.
