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.

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.

Fix alarm wakelock not being released.

Alarm wakelock was not released when the pending intent was served
by the package with a uid not the same as the one which created the
alarm.
Remove advanced for loop from PowerManagerService since the list is

DocumentsUI: Fix the issue of download status was displayed incompletely

The layout arrangement of date, size and summary are unreasonable.
Text was ellipsized when summary has too much characters.

Reconfigure "layout_weight" of date, size and summary can fix this
issue.

Avoid layout passes when updating data activity indicators.

ImageView can optimize out layout passes if old and new drawable have
equal sizes. Take advantage of that by displaying a transparent drawable
with the same size as the in/out drawables when there's no activity
instead of clearing out the drawable in that case.
