Export vpx_codec_enc_init_multi_ver so the vp8 multi res encoder example
can see it when building shared.

vpx_svc_parameters_t contains id, resolution and min/max qp for each spatial layer.
In this change we will use extra config to send min/max qp and scaling factors, then calculate layer resolution inside encoder.

1. This is to align with the ffmpeg implementation
2. Remove APIs for setting quantizers and scale-factors

1. svc_encodeframe.c will not handle frame or stats packets anymore.
The app will process them.
2. Remove APIs that related to these packets.

2. Add read/write for RC stats file
The two pass RC for svc does not work yet. This is just the first
step. We need further development to make it working.

also:
o remove dead code, create_dummy_frame
o Fix a bug in command line handling that caused a segfault if wrong
number of arguments were given.

SVC multiple layer per frame encoding is invoked with vpx_svc_init and
vpx_svc_encode. These interfaces are designed to be invoked from ffmpeg.
Additional improvements:
- make dummy frame handling a bit more explicit
- fixed bug with single layer encodes
- track individual frame sizes and psnrs instead of averages
- parameterized quantizer, 16th scalefactors, more logging,
- enabled single layer encodes to generate baseline
- include new mode for 3 layer I frame with 5 total layers

This reverts commit a82001b1cf, reversing
changes made to f6d870f7ae.
This commit breaks windows builds and needs some work to fix those and
some additional comments.

This patch adds support for building shared libraries when configured
with the --enable-shared switch.
Building DLLs would require more invasive changes to the sample
utilities than I want to make in this patch, since on Windows you can't
use the address of an imported symbol in a static initializer. The best
way to work around this is proably to build the codec interface mapping
table with an init() function, but dll support is of questionable value
anyway, since most windows users will probably use a media framework
lib like webmdshow, which links this library in staticly.
