Posix acls are a truly incredible example of API design. The presence
of a default posix acl in a directory completely changes the meaning of
the `mode` parameter for all system call that create inodes. However,
this new behavior only applies when the inode is first created and not
for any subsequent operations that use the mode, like fchmod.
When a directory has a default posix acl, all inodes created in that
directory get the permissions specified in the default acl. The mode
parameter is treated like a umask where any permissions allowed by the
default acl that are not allowed by the mode parameter are blocked. The
actual umask is ignored in this case.
So to handle this properly we need to set FUSE_DONT_MASK to prevent the
kernel driver from preemptively applying the umask. Then we have to
check if the parent directory has a default posix acl and only apply the
umask to the mode if it does not. This also means that we cannot use
`mkdtemp` because that always creates directories with a mode of 0o700
and since the default posix acl calculation only applies on creation and
not on later operations, we need to apply the proper mode in the very
beginning.

Convert the FD executor to have a more similar interface to the
uring_executor. This has two benefits.
1) This allows a single wrapper `PollOrRing` to be used. It will select
uring or fd transparent to the user, allowing users to get the benefits
of uring when available without changing their code.
2) Having the `PendingWaker` and Registered source manage FD lifetime
removes the need for custom drop implementations for each Future. This
simplifies things so much there is no longer need for the async_core
crate which is removed.

Some function signatures have been slightly changed to take &self and

that the Pic struct itself would be the only object that needs access
to the resample_events rather than each PicState needing it's own copy

Move the Ok(()) return value to a separate expression.
uring_executor::add_future returns (), so this is effectively the same,
but clippy complains about the previous form:

Advertise that we support posix acls in the response to the init
message. Since the VM does access checks before sending the request to
the server, having this disabled meant that the VM was rejecting
requests that should have been allowed to succeed.

The switch to 2 stage mkdir + create broke setgid bit handling on
directories. When this bit is set in a directory all inodes in that
directory should be created with the gid of that directory rather than
the gid of the process that made the call.
BUG=b:152806644
TEST=Set the sgid bit on a directory and verify that new files and
directories inherit the directory's group rather than the group of
the process that created them.

We don't set FUSE_DONT_MASK so the guest kernel will apply the umask
to the mode before sending the request. Just pass it on unmodified.
