libstagefright: add null checking to addPlugin

libstagefright: fix error handling of dlsym()

According 'man dlsym', a NULL return from dlsym() doesn't indicate an error.
The correct way to test for an error is to call dlerror() to clear any old
error conditions, then call dlsym(), and then call dlerror() again to check
whether its return value is not NULL.

libstagefright: add more media mimetypes

This is the first step to add the ffmpeg plugins.

libstagefright: add ExtractorPlugin

The patch allows to load an ExtractorPlugin to extend the functions of
DataSource::sniff and MediaExtractor. A plugin has to implement a C
function getExtractorPlugin to fill the MediaExtractor::Plugin struct.

The filename of the plugin could be specified by the
media.stagefright.extractor-plugin property.

FLACExtractor: Add more sample rates support

In FLACExtractor.cpp, it has function to check file's sample rate.
If the input sample rate is not in its list, it will return "unsupported
sample rate" issue. Modify code to make other sample rates (100,1k,42k,46k)
pass the check

DataSource: Split off ffmpeg sniffer to a second pass, and only if necessary

ffmpeg's sniffer is intended as a grab-all-that-doesn't-work-elsewhere
extractor. Unfortunately, this causes two issues:

- As written, it requires ffmpeg to whitelist any extractors supported
by stagefright, or else it will blindly override them. This has codebase
sync issues, as shown by the VP9 and WAV accidental overrides
- It imposes an in-depth analysis of _all_ media, even that which we
want to be processed quickly by shipping stagefright plugins (hardware
or not). This is mostly noticeable in network streams and thumbnail
generation.

This patch moves FFmpegExtractor to an independent sniffer queue, and
it only invokes it when the regular MediaExtractor hits 1 of 3 conditions:

1 - The confidence in the identified container type is low
2 - No container is identified at all
3 - A video container was found by other extractors, but only 1 stream
(audio or video) was identified.

stagefright: OMX.ffmpeg.* are software decoders, ensure they're treated as such

Wherever the component name for OMX.google soft decoders is used to identify
a software-based component, do the same for ffmpeg. Things like memory management
and window buffers care about this.
