GC: Improve the string parsing for GC parameter setting

Improve the string parsing for GC parameter system property.
Previously we only recoganize plain number for dalvik.vm.heapminfree
and dalvik.vm.heapconcurrentstart, while users tend to use format as
2m.  Improve the string parse to cover such cases.

Set some GC parameters only for dalvik

Commit https://github.com/CyanogenMod/android_frameworks_base/commit/8f566390bceee9f01b1721c4d00b1b246d26be16
fixed parsing of certain GC values. Before the result was "" and so the
if statement was always false, never executing the setTargetHeap* calls.

Now they are executed but ART currently doesn't support setting
heapminfree and heapconcurrentstart resulting in a UnsatisfiedLinkError
Exception.

Check for the used runtime first and only execute the methods for Dalvik.

Alarm: Add one more RTC alarm type for poweroff alarm.

Now we use type of RTC_WAKEUP for the poweroff alarm.
Actually lots of other applications also use this type.
But these applications never expect the device will
power on after it has been shut down. So we need to
add dedicated alarm type for the Deskclock or similar
applications.

Fragment animations are not being saved across configuration changes

As per comment #5 in issue #25994:

The problem here is not that the state isn't saved and restored, the problem is how the BackStackRecord is rebuilt.  The ops themselves do save and restore the state, the problem is in BackStackRecord#addOp.

    void addOp(Op op) {
        if (mHead == null) {
            mHead = mTail = op;
        } else {
            op.prev = mTail;
            mTail.next = op;
            mTail = op;
        }
        op.enterAnim = mEnterAnim;
        op.exitAnim = mExitAnim;
        op.popEnterAnim = mPopEnterAnim;
        op.popExitAnim = mPopExitAnim;
        mNumOp++;
    }

The enter, exit, popEnter and popExit animations are overwritten with whatever is currently in the record, which during the restoration process these are 0 so the values which were saved in the ops is lost.

storage: Don't list removed volumes in storage list

 * Don't tell apps that USB storage or empty SD slots are available for
   use. This fixes errors about trying to create dirs in vold as well
   as the relevant CTS cases.
