If it fails, the buffers can be (partially) uninitialized.
This fixes 'Conditional jump or move depends on uninitialised value(s)'
valgrind warnings.

Since the underlying URLContext read functions are used,
they handle interruption, without having to handle it at
this level.

This avoids hijacking the fd, by reading using the normal
URLContext functions instead. This allowing reading data that has
been buffered in the underlying URLContext.
This avoids using the libraries own send functions that can
cause SIGPIPE.
The fd is still used for polling the lowlevel socket, for
waiting for retries.

These loops can take a lot of time if count is very large.

nut->last_syncpoint_pos doesn't necessarily change between resync
attempts, so find_any_startcode can return the same startcode again.
Thus remember where the last resync happened and don't try to resync
before that.
This can't be done locally in nut_read_packet, because this wouldn't
prevent infinite resync loops, where after the resync a packet is
returned and while reading a following packet the resync happens again.
