Reverts to using tmpfile() for non-Windows platforms. On google3
the test directory does not have write permissions, and hence the
Y4mWriteTest fails. This patch fixes the issue.
On Windows, a temporary file is created in the temp directory
that has write permissions.

The tests pass on linux, mingw, and MS visual studio.

simple_encoder: Flush encoder. According to the current API spec we need
to call vpx_codec_encode() until vpx_codec_get_cx_data() returns NULL.

[spatial svc]Remove CONFIG_SPATIAL_SVC for ss_enable_auto_alt_ref in vpx_codec_enc_cfg to fix heap-overflow issue in asan config

Change-Id: Icdf08501db5f416285f751d316941dfacd2c69ba

When a valid data pointer is given make sure the size is greater than
zero.
A previous check for vp9 was incorrectly removed in:
70500747 Make the api behavior conform to api spec.

No semantics for valid pointers + 0-sized frames are defined for VPx
codecs, so move the check to vpx_codec_decode(). This avoids an assert
in vp9.

+ add some basic invalid param testing for decoder init/decode/destroy

This commit enables encoder to select fast forward transform and
quantization path according to the prediction residual sse/variance,
in the rate-distortion optimization scheme.

Adds a couple of CONFIG_SPATIAL_SVC macros to allow compilation
when spatial-svc is disabled.

- Split vpxenc() into vpxenc() and vpxenc_pipe().
- Drop all but one positional param (the input file) in favor
  of passing args directly to vpxenc.
- Add an extra lossless test that explicitly sets min-q and
  max-q to 0.

We had a very complicated way to initialize cpi->pass from
cfg->g_pass:
switch (cfg->g_pass) {
  case VPX_RC_ONE_PASS:
    oxcf->mode = ONE_PASS_GOOD;
    break;
  case VPX_RC_FIRST_PASS:
    oxcf->mode = TWO_PASS_FIRST;
    break;
  case VPX_RC_LAST_PASS:
    oxcf->mode = TWO_PASS_SECOND_BEST;
    break;
}

cpi->pass = get_pass(oxcf->mode).

Now pass is moved to VP9EncoderConfig and initialization is simple:
switch (cfg->g_pass) {
  case VPX_RC_ONE_PASS:
    oxcf->pass = 0;
    break;
  case VPX_RC_FIRST_PASS:
    oxcf->pass = 1;
    break;
  case VPX_RC_LAST_PASS:
    oxcf->pass = 2;
    break;
}

Replaced encoder and decoder functions to get a pointer
to a reference frame with a common function, vp9_get_ref_frame,
and simplified it.

This was shadowing the use of error_resilient_mode, but with
the opposite sense.
