Martin Fischer 0e4d5eeea7 Implement config subcommand 
The synopsis is as follows.

List all top-level config keys:

    $ ruff config
    allowed-confusables
    builtins
    cache-dir
    ... etc.

List all config keys in a specific section:

    $ ruff config mccabe
    max-complexity

Describe a specific config option:

    $ ruff config mccabe.max-complexity
    The maximum McCabe complexity to allow before triggering `C901` errors.

    Default value: 10
    Type: int
    Example usage:
    ```toml
    # Flag errors (`C901`) whenever the complexity level exceeds 5.
    max-complexity = 5
    ```

Martin Fischer f5a3c90288 Rename new `ruff rule` output format to "pretty" 
The new `ruff rule` output format introduced in
551b810aeb doesn't print Markdown but
rather some rich text with escape sequences for colors and links,
it's actually the "text" format that prints Markdown, so naming the new
format "markdown" is very confusing. This commit therefore renames it to
"pretty".

This isn't a breaking change since there hasn't been a release yet.

perf: Use custom allocator (#2768) 
This PR replaces the system allocator with a custom allocator to improve performance:

* Windows: mimalloc
* Unix: tikv-jemallocator

## Performance:

* Linux
  * `cpython --no-cache`: 208.8ms -> 190.5ms
  * `cpython`: 32.8ms -> 31ms
* Mac: 
  * `cpython --no-cache`: 436.3ms -> 380ms
  * `cpython`: 40.9ms -> 39.6ms
* Windows: 
  * `cpython --no-cache`: 367ms -> 268ms
  * `cpython`: 92.5ms -> 92.3ms
  
## Size

* Linux: +5MB from 13MB -> 18MB (I need to double check this)
* Mac: +0.7MB from 8.3MB-> 9MB
* Windows: -0.16MB from 8.29MB -> 8.13MB (that's unexpected)

Derive `explanation` method on Rule struct via rustdoc (#2642) 
```console
❯ cargo run rule B017
    Finished dev [unoptimized + debuginfo] target(s) in 0.13s
     Running `target/debug/ruff rule B017`
no-assert-raises-exception

Code: B017 (flake8-bugbear)

### What it does
Checks for `self.assertRaises(Exception)`.

## Why is this bad?
`assertRaises(Exception)` can lead to your test passing even if the
code being tested is never executed due to a typo.

Either assert for a more specific exception (builtin or custom), use
`assertRaisesRegex` or the context manager form of `assertRaises`.
