84d1f29d47 btrfs-progs: send: check for output file existence before creating 
In some cases the root might not be able to create the output file (and
streaming to stdout is not an option). Make the output file creation two
step and let it work if the file is already created.

7d405df0da btrfs-progs: send: fix handling of -c option 
When two or more -c options are specified, cannot find a suitable
parent. So, output stream is bigger than correct one.

c29fea4344 btrfs-progs: use correct type for device id iteration in get_fs_info 
Coverity reports (CID 1374096) that there's return value overflow of
ret from get_device_info, but this most likely cannot happen. There's
another minor issue where we use int to iterate over devids.

92847b5cd6 btrfs-progs: crc32: use fallback implementation for unaligned buffers 
ASAN reports that at some point the crc function gets an unaligned
buffer. It's the optimized intel version that casts char to ulong, the
buffer is the embedded filename in the directory items.
