I want to build a local 2018-01-12 rustc. This is what I do:

git clone https://github.com/rust-lang/rust

git checkout 73ac5d6

./x.py build && sudo ./x.py install

However, it generate such errors after ./x.py build:

➜  rust git:(73ac5d6) ✗ sudo ./x.py install
info: looks like you are running this command under `sudo`
      and so in order to preserve your $HOME this will now
      use vendored sources by default. Note that if this
      does not work you should run a normal build first
      before running a command like `sudo make install`

Update cargo-vendor usage

This contains a variety of updates to clean up the usage of cargo-vendor.

- Remove the install step for the old cargo-vendor now that it is built-in to cargo and available in the stage0 install.
- Update installation instructions, dealing with vendoring. The current instructions of running `sudo ./x.py install` is broken, it will almost always fail (since the vendor directory doesn't exist). Since the steps for properly handling this are numerous, I'm recommending removing the suggestion to use `sudo` altogether.
- If the sudo-forced-vendoring detects that the vendor directory is not available, abort with instructions on how to fix.
- Now that cargo-vendor is built-in, automatically run it if it looks like it is needed.
- Update instructions on how to install cargo.
- Remove the unused markdown link references in README/CONTRIBUTING. This reverts most of #44935. These references don't do anything if they are unused.

Closes #49269
