Specifying O_DIRECT in the 9p device doesn't actually work correctly and
leads to an error. O_DIRECT handling in the fs device works correctly
but also makes it look much worse in disk I/O benchmarks because the
block device gets the benefit of the host cache while the fs device
depends on the performance of the actual storage device.

As described in:
https://doc.rust-lang.org/edition-guide/rust-2018/ownership-and-lifetimes/default-match-bindings.html
which also covers the new mental model that the Rust Book will use for
teaching binding modes and has been found to be more friendly for both
beginners and experienced users.
Before:
match *opt {
Some(ref v) => ...,
None => ...,
}
After:
match opt {
Some(v) => ...,
None => ...,
}

This is an easy step toward adopting 2018 edition eventually, and will
make any future CL that sets `edition = "2018"` this much smaller.
The module system changes in Rust 2018 are described here:
https://doc.rust-lang.org/edition-guide/rust-2018/module-system/path-clarity.html
Generated by running:
cargo fix --edition --all
in each workspace, followed by bin/fmt.
TEST=cargo check
TEST=cargo check --all-features
TEST=cargo check --target aarch64-unknown-linux-gnu

We updated the production toolchain from 1.30 to 1.31 in CL:1366446.
This CL does the same upgrade for the local developer toolchain and
Kokoro.
The relevant changes are in rust-toolchain and kokoro/Dockerfile.
The rest are from rustfmt.
TEST=cargo fmt --all -- --check
TEST=as described in kokoro/README.md

Don't allow clients to create files and directories that are writable by
anyone other than the user. This is equivalent to having a umask of
022.

We calculate the size of the buffer to allocate for a read message by
finding the minimum of the requested size and the number of bytes left
in the response message buffer.
However, we then turned around and used an unsafe block to set the
length of the allocated buffer to the requested size rather than the
calculated size. This could lead to memory corruption if the file we
were trying to read had enough bytes to fill up the whole buffer and the
requested size was larger than the max message size.
Replace both unsafe blocks with a resize function instead. The
compiler is smart enough to turn this into a memset and
zero-initializing a few KB of memory is not that expensive.
