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Pandoc components of the Makefile are no longer used, and as such the corresponding components of the documentation are out of date.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.
Addresses Issue #24214

Implemented count, nth, and last in constant time for Windows, Chunks,
and ChunksMut created from a slice.
Included checks for overflow in the implementation of nth().
Also added a test for each implemented method to libcoretest.

This commit leverages the runtime support for DWARF exception info added
in #27210 to enable unwinding by default on 64-bit MSVC. This also additionally
adds a few minor fixes here and there in the test harness and such to get
`make check` entirely passing on 64-bit MSVC:
* The invocation of `maketest.py` now works with spaces/quotes in CC
* debuginfo tests are disabled on MSVC
* A link error for librustc was hacked around (see #27438)
I was not able to come up with tests that would expose this bug, as, apparently, Rust types of the args are not used for anything but debug logging.
Thanks to @luqmana for pointing this out!
LLVM might perform tail merging on the calls that initiate the unwinding
process which breaks debuginfo and therefore this test. Since tail
merging is guaranteed to break debuginfo, it should be disabled for this
test.
This allows us to restore a testcase that I had to remove earlier
because of the same problem, because back then I didn't realize that
disabling tail merging was an option.

As title :-)
Part of #24407.

This will need merging with E0193, so probably want to delay any r+ until that goes in and I can merge myself.
See line 181: The lookup should start with the random index and iterate from there.
Also locked stdout (which makes it a bit faster on my machine). And the `make_lookup` function now uses `map` (as the TODO asked for).
Perhaps the multi-thread output from the fasta benchmark could be used to speed it up even more.
