This patch was to fix the vpxdec fuzzing3 test failure. When an
error occurs, setjmp() is invoked, which calls the decoder
removing routine. In multiple thread situation, other threads
could try to access the frame context memory that is already
deallocated, thus causing a segfault.
An invalid unit test was added for this issue.

Covers all profiles and input formats. The tests check if the
encode succeeds and if the psnr is sane.

Add a test vector to show the cases where segmentation map is preserved
from frome to frame as outlined in the inquiry in issue 761.
