Should provide us with better outputs on process failure, also makes
unwinding better and is generally recommended over `exit()`.

Instead of the custom logger impl, which limits the features we can
easily provide for users.
This introduces the `BCACHEFS_LOG` environment variable for setting the
log verbosity. Setting `BCACHEFS_LOG=trace`, e.g. in a test environment,
will yield all log messages.
Also I think it's reasonable to print INFO level logs by default.

We already can check if an fs is encrypted with `bcachefs unlock -c`.
With this option we can now instead check if we have a key but not
actually mount by not specifying a mount point. e.g.
```sh
if bcachefs mount -k fail "$blkdev"`; then
echo "device is unlocked!"
fi
```
Not sure what the original intent for this was. For scenarios where
encryption is simply not supported on principle?

This changes the semantics of some arguments related to unlocking and
slightly changes the unlocking logic. Also update help formatting/text.
Instead of defaulting to `UnlockPolicy::Ask`, the argument becomes
optional. That means if it is specified, the user really wants that
specific policy. Similar to how `passphrase_file` also works.
This also extends `UnlockPolicy` to override `isatty` detection.

The term option is already used for mount options and the `Option` type.
In other modules it's just called `cli`, so let's do that here as well.

We lose that bit of info but it's weird to require a parameter simply
because we want to use it for a log message.

The keyctl_search() C function returns a long, which is already
reflected in the KeyHandle._id type. The search_keyring() helper
function currently returns a Result<i64>, which breaks 32-bit builds for
e.g. armv7l:
error[E0308]: mismatched types
--> src/key.rs:121:16
|
121 | Ok(key_id)
| -- ^^^^^^ expected `i64`, found `i32`
| |
| arguments to this enum variant are incorrect
...
error[E0308]: mismatched types
--> src/key.rs:135:24
|
135 | _id: id,
| ^^ expected `i32`, found `i64`
Fix this by changing search_keyring() to return a Result<c_long>.

Previously, using `bcachefs unlock -k session` would still cause mount

The copy_data function takes a start and an end parameter as the range
of bytes to copy, but it was called with a start and a length parameter.
This resulted in incomplete file copies. Fix it by passing the end of
the range instead of the length.

This kernel commit: 65bd442397274347e721a89c2c4882a392bae982 removes
BTREE_ITER_cached from bch2_btree_insert_trans, which causes the

It's kind of stupid to use this macro if we have to deref the parameter
