Fix getService should retry on DEAD_OBJECT

If getService sees DEAD_OBJECT or nullptr when calling
interfaceChain on the retrieved service, it should
retry. Otherwise (e.g. TRANSACTION_FAILED for selinux
denials), it should bail out.

This retry doesn't happen for tryGetService.

Test: calling Debug.getMemoryInfo from apps does not hang
Test: kill system_server, audio_server restarts exactly once
      (tested 10/10 times)
Test: taking screenshots / using camera / using maps
Test: adb push
$OUT/data/nativetest/VtsHalNfcV1_0TargetTest/VtsHalNfcV1_0TargetTest
/data/local/tmp && adb shell
/data/local/tmp/VtsHalNfcV1_0TargetTest
Test: hidl_test

hidl-gen user guide

1. Build

croot
make hidl-gen

2. Run

hidl-gen -o output-path -L language (-r interface-root) fqname

output-path: directory to store the output files.
language: output file for given language. e.g.c++, vts..

fqname: fully qualified name of the input files.
For singe file input, follow the format: package@version::fileName
For directory input, follow the format: package@version

interface-root(optional): prefix and root path for fqname.
If not set, use the default prefix: android.hardware and default root path
defined in $TOP.

examples:

croot
hidl-gen -o output -L c++ -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0::INfc.hal
hidl-gen -o output -L vts -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0
hidl-gen -o test -L c++ -r android.hardware:hardware/interfaces -r android.hidl:system/libhidl/transport android.hardware.nfc@1.0
