Subject: [PATCH] Downscale and retry also on early MediaCodec error

The new retry mechanism with a lower definition only worked if the error
occurred during encode(). For example:

    java.lang.IllegalStateException
        at android.media.MediaCodec.native_dequeueOutputBuffer(Native Method)
        at android.media.MediaCodec.dequeueOutputBuffer(MediaCodec.java:3452)
        at com.genymobile.scrcpy.ScreenEncoder.encode(ScreenEncoder.java:114)
        at com.genymobile.scrcpy.ScreenEncoder.internalStreamScreen(ScreenEncoder.java:95)
        at com.genymobile.scrcpy.ScreenEncoder.streamScreen(ScreenEncoder.java:61)
        at com.genymobile.scrcpy.Server.scrcpy(Server.java:80)
        at com.genymobile.scrcpy.Server.main(Server.java:255)

However, MediaCodec may also fail before encoding, during configure() or
start(). For example:

    android.media.MediaCodec$CodecException: Error 0xfffffc0e
        at android.media.MediaCodec.native_configure(Native Method)
        at android.media.MediaCodec.configure(MediaCodec.java:1956)
        at android.media.MediaCodec.configure(MediaCodec.java:1885)
        at com.genymobile.scrcpy.ScreenEncoder.configure(ScreenEncoder.java:158)
        at com.genymobile.scrcpy.ScreenEncoder.streamScreen(ScreenEncoder.java:68)
        at com.genymobile.scrcpy.Server.scrcpy(Server.java:28)
        at com.genymobile.scrcpy.Server.main(Server.java:110)

Also downscale and retry in these cases.
