block: implement is_allocated for raw

Either FIEMAP, or SEEK_DATA+SEEK_HOLE can be used to implement the

stream: tweak usage of bdrv_co_is_allocated

is_allocated_base has complex semantics that are not really usable

state for the top bs is moved to the caller. The resulting function
is more generally useful....

block: prevent snapshot mode $TMPDIR symlink attack

In snapshot mode, bdrv_open creates an empty temporary file without
checking for mkstemp or close failure, and ignoring the possibility
