Types with interior mutability like `Cell` and `RefCell` can be used to
skirt the restriction on mutating mutable values inside an immutable
container.
This adds detailed diagnostics for `E0383`, 'partial reinitialization of
uninitialized structure'.
This is part of rust-lang/rust#24407.

The corrected signature of `ioctl` broke some crates on crates.io, and it's not
currently worth the major version bump of libc, so for now keep the old
signature around for crates.io builds only with a comment to remove it at a
future date.
This should allow libc on crates.io to update to the master version in-tree.
I've verified that this was the only breakage of substance between the version
libc is currently built with and today's master branch.
Initial version of PR had an DerefMut implementation, which was later removed
because it may cause mutable reference aliasing.
Suggest how to implement mutability with reentrant mutex and remove the claim we
implement DerefMut.
Per @steveklabnik's comment [here](https://github.com/rust-lang/cargo/issues/739#issuecomment-130085860), the Pandoc components of the Makefile are no longer used, and as such the corresponding components of the documentation are out of date.
- I've removed the Pandoc (and therefore also LaTeX) elements of the makefile and confirmed that the build proceeds correctly.
- I updated the documentation to reference `rustdoc` and of Pandoc.

Provides a custom implementation of Iterator methods `count`, `nth`, and `last` for the structures `slice::{Windows,Chunks,ChunksMut}` in the core module.
These implementations run in constant time as opposed to the default implementations which run in linear time.

Pretty-printed files sometimes start with #![some_feature], which
looks like a shebang line and confuses Windows builds into thinking
they are executables.

we also must know that the formal types of the arguments are WF.)
warnings. It also checks more conditions than the old code. Keep the
old wf code around unchanged so that we can continue to issue errors for
the cases where we used to report errors.
As part of this, remove the where-clauses-must-reference-parameter rule,
which is easily circumvented.
