When the protocol is missing ffurl_alloc() should return
AVERROR_PROTOCOL_NOT_FOUND instead of AVERROR(ENOENT).

pthread_wait_cond can wake up unexpectedly (Wikipedia: Spurious_wakeup).

The FF_THREAD_SLICE thread mechanism could spontaneously execute
jobs or allow the caller of avctx->execute to return before all
jobs were complete.

Test both cases to ensure the wakeup is real.

Use an helper function to seek by sector to avoid possible mistakes
due shifting by WTV_SECTOR_BITS a 32bit integer.

Contrary to common intuition, a 32 bit integer left shifted
by a 64 bit integer does not promote the 32 bit integer to
64 bit before shifting.

A few fate instances on OS/2, OpenBSD, FreeBSD and IA64 linux currently
still fail a few tests with a maxdiff of 6.

This makes sure that pointers from av_strdup are reallocable,
which is used in av_dict_set if the AV_DICT_APPEND flag is set.

Nothing should rely on pointers from av_strdup being aligned.
