Use `std::mem::{size_of, size_of_val, align_of, align_of_val}` from the
prelude instead of importing or qualifying them.
These functions were added to all preludes in Rust 1.80.

The previous commit updated `rustfmt.toml` appropriately. This commit is
the outcome of running `x fmt --all` with the new formatting options.

Many tiny changes to stdlib doc comments to make them consistent (for example
"Returns foo", rather than "Return foo", per RFC1574), adding missing periods, paragraph
breaks, backticks for monospace style, and other minor nits.

This is an initial commit of network support for Xous.
On hardware, is backed by smoltcp running via a Xous server in a
separate process space.
This patch adds TCP and UDP client and server support as well as DNS
resolution support using the dns Xous server.

When updating memory flags via `update_memory_flags()`, ensure we
multiply the slice length by the element size to get the full memory
size.

The amount of memory allocated was multiplied by sizeof::<T>(), so the
amount of memory to be freed should also be multiplied by sizeof::<T>().

The `ret1` and `ret2` return values from lend operations are returned in
$a1 and $a2. This function incorrectly pulled them from $a6 and $a7,
causing them to always be `0`.

ticktimer server.

Xous has a concept of `services` that provide various features.
Processes may connect to these services by name or by address. Most
services require a name server in order to connect.
Add a file with the most common services, and provide a way to connect
to a service by querying the name server.

Xous has no C FFI. Instead, all FFI is done via syscalls that are
specified in Rust. Add these FFI calls to libstd, as well as some of the
currently-supported syscalls.
This enables Rust programs to interact with the Xous operating system
while avoiding adding an extra dependency to libstd.
