According to the corresponding section, accessing a mutable static variable requires `unsafe` too, and I believe it counts as as language level feature. Add it to the relevant list in the Unsafety section.
Previously this was adding one-too-many `..`s to the path for the
`gotosrc=...` links for local crates. Also, the `root_path` already ends
in `/`s so a trailing / shouldn't be added after the root (some servers
treat `...//...` different to `.../...` including the one running
doc.rust-lang.org).

Because IPv4 address conversion doesn't consider big-endian target, I add functions to handle that.
These function names may need to be changed, but I can't come up with a good one.
This commit moves reflection (as well as the {:?} format modifier) to a new
libdebug crate, all of which is marked experimental.
This is a breaking change because it now requires the debug crate to be
explicitly linked if the :? format qualifier is used. This means that any code
using this feature will have to add `extern crate debug;` to the top of the
crate. Any code relying on reflection will also need to do this.
Closes#12019

My main goals were:
- be clear when we talk about "references" and "pointers"
- remove Managed boxes completely and the concept of GC.

When spawning a process, stdio file descriptors can be configured to be ignored,
which basically means that they'll be closed. Currently this is done by
literally closing the file descriptors in the child, but this can have adverse
side effects if the child process then opens a new file descriptor, assigning it
to a stdio number.
To work around the problems of the child, this commit alters the process
spawning code to map stdio fds to /dev/null on unix (and a similar equivalent on
windows) when they are specified as being ignored. This should allow spawned
programs to have more expected behavior when opening new files.
Closes#14456
This adjusts the "unlinked native library" warning one receives when
compiling with `crate_type="staticlib"`. The warning is just trying to
tell the user that they need to link against these libraries, but the
old text wasn't making this obvious; the new text says this explicitly.
Change `for` desugaring & make refutable pattern errors more precise
This changes for to desugar to the `let`-based pattern match as described in #14390, and adjusts the compiler to use this information for error messages that even mention that it's in a `for` loop.
Also, it makes the compiler record the exact positions of refutable parts of a pattern, to point to exactly them in error messages.
This ensures that a public typedef to a private item is ensured to be public in
terms of linkage. This affects both the visibility of the library's symbols as
well as other lints based on privacy (dead_code for example).

messages when the pattern is refutable.
This means the compiler points directly to the pattern and said that the
problem is the pattern being refutable (rather than just saying that
some value isn't covered in the `match` as it did previously).
Fixes#14390.
The current tutorial says that the only way to get master is to build from source, which isn't true anymore - nightly binaries and an installer for Mac OS X are now available at the install page: http://www.rust-lang.org/install.html . Feedback very much welcome! Addresses issue #13578.
