Add a tool to run x.py from any subdirectory
This adds a binary called `x` in `src/tools/x`. All it does is check the
current directory and its ancestors for a file called `x.py`, and if it
finds one, runs it.

By installing x, you can easily `x.py` from any subdirectory.

It can be installed globally with `cargo install --path src/tools/x`

00e7ff44ca .gitignore: Don't ignore a file that exists in the repository
.gitignore should not ignore files that exist in the repository. The
ignore of .cargo applies to the committed .cargo directory used in an
example:

$ git ls-files --exclude-standard --ignored
src/test/run-make/thumb-none-qemu/example/.cargo/config

Explicitly un-ignore that file.

Rollup merge of - pawroman:cleanup_unicode_script, r=varkor
Refactor unicode.py script

Hi, I noticed that the `unicode.py` script used some deprecated escapes in regular expressions. E.g. `\d`, `\w`, `\.` will be illegal in the future without "raw strings". This is now fixed. I have also cleaned up the script quite a bit.

## Escape deprecation

OK (note the `r`):
`re.compile(r"\d")`

Deprecated (from Python 3.6 onwards, see [here][link1] and [here][link2]):
`re.compile("\d")`.

[link1]: https://docs.python.org/3.6/whatsnew/3.6.html#deprecated-python-behavior
[link2]: https://bugs.python.org/issue27364

This was evident running the script using Python 3.7 like so:

```
$ python3 -Wall unicode.py
unicode.py:227: DeprecationWarning: invalid escape sequence \w
  re1 = re.compile("^ *([0-9A-F]+) *; *(\w+)")
unicode.py:228: DeprecationWarning: invalid escape sequence \.
  re2 = re.compile("^ *([0-9A-F]+)\.\.([0-9A-F]+) *; *(\w+)")
unicode.py:453: DeprecationWarning: invalid escape sequence \d
  pattern = "for Version (\d+)\.(\d+)\.(\d+) of the Unicode"
```

The documentation states that
> A backslash-character pair that is not a valid escape sequence now generates a DeprecationWarning. Although this will eventually become a SyntaxError, that will not be for several Python releases.

## Testing

To test my changes, I had to add support for choosing the Unicode version to use. The script will default to latest release (which is 12.0.0 at the moment, repo has 11.0.0 checked in).

The script generates the exact same output for version 11.0.0 with Python 2.7 and 3.7 and no longer generates any deprecation warnings:

```
$ python3 -Wall unicode.py -v 11.0.0
Using Unicode version: 11.0.0
Regenerated tables.rs.
$ git diff tables.rs
$ python2 -Wall unicode.py -v 11.0.0
Using Unicode version: 11.0.0
Regenerated tables.rs.
$ git diff tables.rs
$ python2 --version
Python 2.7.16
$ python3 --version
Python 3.7.3
```

## Extra functionality

Furthermore, the script will check and download the latest Unicode version by default (without the `-v` argument). The `--help` is below:

```
$ ./unicode.py --help
usage: unicode.py [-h] [-v VERSION]

Regenerate Unicode tables (tables.rs).

optional arguments:
  -h, --help            show this help message and exit
  -v VERSION, --version VERSION
                        Unicode version to use (if not specified, defaults to
                        latest available final release).
```

## Cleanups

I have cleaned up the code quite a bit, with Python best practices and code style in mind. I'm happy to provide more details and rationale for all my changes if the reviewers so desire.

One externally visible change is that the Unicode data will now be downloaded into `src/libcore/unicode/downloaded` directory suffixed by Unicode version:

```
$ pwd
.../rust/src/libcore/unicode
$ exa -T downloaded/
downloaded

3b208d2dac Reduce the size of static data in std_unicode::tables.
`BoolTrie` works well for sets of code points spread out through
most of Unicode’s range, but is uses a lot of space for sets
with few, mostly low, code points.

This switches a few of its instances to a similar but simpler trie
data structure.

 ## Before

`size_of::<BoolTrie>()` is 1552, which is added to
`table.r3.len() * 8 + t.r5.len() + t.r6.len() * 8`:

* `Cc_table`: 1632
* `White_Space_table`: 1656
* `Pattern_White_Space_table`: 1640
* Total: 4928 bytes

 ## After

`size_of::<SmallBoolTrie>()` is 32, which is added to
`t.r1.len() + t.r2.len() * 8`:

* `Cc_table`: 51
* `White_Space_table`: 273
* `Pattern_White_Space_table`: 193
* Total: 517 bytes

 ## Difference

Every Rust program with `std` statically linked should be about 4 KB smaller.

31a8638e5e rustbuild: Tweak for vendored dependencies
A few changes are included here:

* The `winapi` and `url` dependencies were dropped. The source code for these
  projects is pretty weighty, and we're about to vendor them, so let's not
  commit to that intake just yet. If necessary we can vendor them later but for
  now it shouldn't be necessary.

* The `--frozen` flag is now always passed to Cargo, obviating the need for
  tidy's `cargo_lock` check.

* Tidy was updated to not check the vendor directory

de1838148c Add /obj/ to .gitignore
This is the build directory our buildbots use, and right now the bots are
running `git clean -f -f -d` to remove all untracked files between runs and this
is accidentally deleting `obj`, so we're building LLVM a lot.

Hopefully this keeps the bots caching `obj` so we can clean it out manually and
leave LLVM around.

046e6874c4 Add a Cargo-based build system
This commit is the start of a series of commits which start to replace the
makefiles with a Cargo-based build system. The aim is not to remove the
makefiles entirely just yet but rather just replace the portions that invoke the
compiler to do the bootstrap. This commit specifically adds enough support to
perform the bootstrap (and all the cross compilation within) along with
generating documentation.

More commits will follow up in this series to actually wire up the makefiles to
call this build system, so stay tuned!
