Introduce an env. variable for users that have a broken blkid which
renders the udev db as incomplete. Only checks for the existence
of the variable, not its value.

If the udev database contains information about bcachefs, utilize it.
Otherwise, resort to traversing block devices and checking for
bcachefs super blocks.

Add an environment variable that indicates we prefer to run bcachefs
code in the kernel, not userspace - this is for the test environment
where it's easier to debug kernel code.

It is more idiomatic to use `commands::mount` than
`commands::cmd_mount`.

Without the single char (with ':' if optarg expected) only the long
argument string would successfully parse.
For example, now "-lasdf" parses the same as "--label asdf"
We need to check when stdin has been closed - otherwise we'll spin
because select() will return immediately.

If we pass a symlink for a single device node we fail to locate the
device node. Canonicalize the device node before we try to read up
the superblock.
This allows the following to work.
# bcachefs mount /dev/mapper/vg-thinvolume /mnt/lv_thin

Instead of requiring the user to supply all the device nodes for a
multi-device FS, allow them to specifiy 1 of them. We then fetch
the UUID for the FS and then find all the disks on the system that
match this UUID.
This allows me to bring up a bcachefs FS in /etc/fstab by using a
UUID. This works because it appears the mount command looks up
the UUID, finds an entry in /dev/disk/by-uuid and then passes that
found device node to mount.bcachefs which fails with
`insufficient_devices_to_start` as bcachefs is expecting a list of
devices with a ":" between them. This behavior is preserved if a
user specifies a list of all the needed device nodes to bring up
the FS.

This resolves build warnings and failures for architectures where the
Linux userspace `asm/types.h` header defines 64-bit types (u64, s64) as
`long` instead of `long long`.
By defining `__SANE_USERSPACE_TYPES__`, these types are defined as
`long long` instead.
