c->out can hold a valid picture on bitstream errors after 4903d87b when frame multi-threading is used. Output this picture instead of returning the return value of dav1d_parse_obus(). Fixes `assert(dst->data[0] == ((void*)0));` in dav1d_picture_ref with clusterfuzz-testcase-minimized-dav1d_fuzzer_mt-5743306491822080. Also fixes a memory leak of frames with clusterfuzz-testcase-minimized-dav1d_fuzzer_mt-5655593017147392. Credits to oss-fuzz.

ftello isn't available on MSVC. On MinGW, both ftello and _ftelli64 are available. MinGW provides the _ftelli64 even on msvcrt versions that don't actually have such a function by providing a statically linked wrapper. But since the ftello function also is available (also provided as a similar wrapper), keep using that.

off_t isn't available in all environments. On Ubuntu 16.04, GCC 5.4, glibc 2.23, off_t is defined by stdio.h normally, but if building with -std=c99 (which dav1d does), it no longer is defined. If fcntl.h is included additionally (which isn't done in dav1d), it still gets defined though. off_t isn't available in MSVC at all.
