The term 'mixed' is confusing as it's commonly used for mised block
group profiles created by 'mkfs.btrfs --mixed'. We're interested in
multiple profiles for each type, so use the term 'multiple'.

When compiling with clang, this warning is shown:
common/utils.c:404:3: warning: declaration does not declare anything [-Wmissing-declarations]
__attribute__ ((fallthrough));
This attribute seems to silence the same warning in GCC. Changing this
attribute with /* fallthrough */ fixes the warning for both gcc and
clang.
Full support for the attribute will be in clang 10, gcc supports that
now. Let's use what works for both and switch to the attribute in the
future.

With the introduction of xxhash64 to btrfs-progs we created a crypto/
directory for all the hashes used in btrfs (although no
cryptographically secure hash is there yet).
Move the crc32c implementation from kernel-lib/ to crypto/ as well so we
have all hashes consolidated.

This adds a global --format option to request extended output formats
from each command.
We currently only support text mode. Command help reports what
output formats are available for each command. Global help reports
what valid formats are.
If an invalid format is requested, an error is reported and lists the
valid formats.
Each command sets a bitmask that describes which formats it is capable
of outputting. If a globally valid format is requested of a command
that doesn't support it, an error is reported and command usage dumped.
Commands don't need to specify that they support text output. All
commands are required to output text.
