This trait is meant to abstract whether a reader is actually implemented with an underlying buffer. For all readers which are implemented as such, we can efficiently implement things like read_char, read_line, read_until, etc. There are two required methods for managing the internal buffer, and otherwise read_line and friends can all become default methods.

These commits create a `Buffer` trait in the `io` module which represents an I/O reader which is internally buffered. This abstraction is used to reasonably implement `read_line` and `read_until` along with at least an ok implementation of `read_char` (although I certainly haven't benchmarked `read_char`).

Add the `popular-crates` binary This program downloads crates info from <https://crates.io/> and builds a TOML file that can be fed to `lintcheck`. I have been asked, on various pull requests, what the result of `lintcheck` was. However, the default configuration file for lintcheck is limited. This `popular-crates` program allows building a recent list of the recently most downloaded crates from <https://crates.io> and feed it to `lintcheck`. Using it, it was easy to test two new lints against the 500 recently most downloaded crates to ensure that there was no regression. changelog: none
