One notable feature is this this adds support for the experimental
`let x = loop { ... break $expr; }` syntax. This also includes a
test for formatting all the break and continue variations.
* Change required to prevent a trailing space at the end of a separate module being propagated
* Detect the start of the output file rather than the start of the input file when deciding whether to output preceding snippets - this stops unnecessary whitespace and blank lines from being inserted when spans and statements are output in an order other than that from the input file.
* Add code to prevent space from being added with the prefix snippet if a) the snippet is entirely horizontal whitespace, or b) the snippet contains whitespace followed by a newline. This prevents trailing spaces at the end of a line from being added.
* Tests for this issue
* Tidy up `match` statements
* Add test with blank lines between `use` statements
* Add config options for combinations of lines and items
* Reordering of import lines implemented.
* Changed nested matches to tuple pattern matching
* Added ordering of path list items to the ordering of use declarations
* Move `format_imports` and `format_import` methods to `imports.rs`
* Add comment to explain how `use` declarations are split off while walking through a module
* Change `ImportReordering` config option to separate boolean options
This commit adds a very rough implementation of handling the specified
line ranges in `config.file_lines_map` for statements. It reformats a
statement if its span is fully contained in the set of lines specified
for the file.
The implementation here is intended as a proof of concept, and
demonstration that the machinery added in the preceding commits is
functional. A final implementation would likely hook in via the
`Rewrite` trait.

This commit adds a `codemap` module, and moves the `CodemapSpanUtils`
added in #857 to it. This is preparation for adding more `Codemap`
specific utilities.

* Handle pub(restricted)
This commit properly handles pub(restricted) as introduced in RFC 1422
[0]. The syntax support was added in #971, but they were not correctly
formatted.

* Drop #[inline] attribute on format_visibility
* Make newly non-failing functions return String
The change to `format_visibiilty` means that `format_header` and
`format_unit_struct` can no longer fail. Their return type is updated to
reflect that.
* Handle attributes (including doc comments) on inline modules
Closes#22Closes#684
* Tweak the rules for changing indentation in comments (to do it less often).
Most of the churn on this bump comes from the `Visibility` enum changing
from
pub enum Visibility {
Public,
Inherited,
}
to
pub enum Visibility {
Public,
Crate,
Restricted { path: P<Path>, id: NodeId },
Inherited,
}
which require taking `Visibility` by reference in most places. The new
variants are not handled at this point.

Removed unneeded comment
Commented line wrapping conditions
Removed prefix param on `rewrite_associated_type`
Merged `rewrite_associated_static` into `rewrite_static`
Added extra tests
This commit adds a CodeMapSpanUtils extension trait on CodeMap, and
moves some functions to methods there:
- span_after
- span_after_last
- span_before
This better reflects them being lookup methods on the codemap.
This commit tidies up handling of `write_mode` by setting it in the
config at the start, and removing the `write_mode` parameter threaded
throughout the formatting process.
Also from @marcusklaas:
Refactor code output functions
Specifically, `write_all_files` no longer returns a HashMap. It would sometimes
contain items, and sometimes be empty. When "fixed" newlines are required, this
must now be done with a separate call. The tests use this strategy and should now pass!
