Add doc for impl From for Error As part of issue #51430 (cc @skade). The impl is very simple, let me know if we need to go into any details.

Update documentation for fill_buf in std::io::BufRead Brings the documentation in line with the BufReader implementation. Fixes #48022. This is my first PR, and I think the `E-easy` label is very cool, as so is the practice of describing the fix but leaving it for someone else; it really makes it a lot less intimidating to get started with something!

Implement always-fallible TryFrom for usize/isize conversions that are infallible on some platforms This reverts commit 837d6c70233715a0ae8e15c703d40e3046a2f36a "Remove TryFrom impls that might become conditionally-infallible with a portability lint". This fixes #49415 by adding (restoring) missing `TryFrom` impls for integer conversions to or from `usize` or `isize`, by making them always fallible at the type system level (that is, with `Error=TryFromIntError`) even though they happen to be infallible on some platforms (for some values of `size_of::<usize>()`). They had been removed to allow the possibility to conditionally having some of them be infallible `From` impls instead, depending on the platforms, and have the [portability lint](https://github.com/rust-lang/rfcs/pull/1868) warn when they are used in code that is not already opting into non-portability. For example `#[allow(some_lint)] usize::from(x: u64)` would be valid on code that only targets 64-bit platforms. This PR gives up on this possiblity for two reasons: * Based on discussion with @aturon, it seems that the portability lint is not happening any time soon. It’s better to have the conversions be available *at all* than keep blocking them for so long. Portability-lint-gated platform-specific APIs can always be added separately later. * For code that is fine with fallibility, the alternative would force it to opt into "non-portability" even though there would be no real portability issue.

Add some performance guidance to std::fs and std::io docs Adds more documentation about performance to various "read" functions in `fs` and `io`, and to `BufReader`/`BufWriter`, with the goal of helping developers choose the best option for a given task.
