Add inverse hyperbolic functions
Fixed type signature of uninhabited method.

Added unit test to prevent similar mistakes from happening again. The
previous method was wrong because it dereferenced a pointer to a void type to
match on the result. No self pointer was needed, and the correct method
signature took the self value by value.
Remove re-exports from libcore/core.rc

Also fix up all the fallout elsewhere throughout core. It's really nice being
able to have the prelude.
revert PriorityQueue to using init()

uninit() would result in potentially running a destructor on arbitrary
memory if the Ord implementation throws
Add ldexp and frexp functions
Remove unnecessary infinity check
auto merge of #6456 : brson/rust/libuv, r=brson

This includes 26fa6f8 which fixes #6258

@ILyoan I ported your patches forward and confirmed that they build but you should be aware of this upgrade.

I'm not quite sure how resolution works with traits, but it seems to me like the public imports at the top-level of the core crate were leaking into the sub-crates, but that could also be working as intended. Regardless, things compile without the re-exports now.
auto merge of #6463 : bjz/rust/numeric-traits, r=thestinger

This is part of the numeric trait reform tracked on issue #4819
Move `position` and `rposition` methods to `ImmutableVector` trait
libstd: impl Num for BigUint/BigInt
Update .gitignore
libstd: impl `Orderable` for `BigUint`/`BigInt`
libstd: `Rational` requires `Integer` as type bounds instead of `Num`
libstd: `Ratio` requires `Clone` instead of `Copy`

This allows creating `Ratio<T>` which `T` is non-implicitly copyable types
such as `BigInt`.
libstd: Add tests for BigRational
Replace shared/unique by managed/owned in the tutorial
Issue #5967: Make rvalues mutable
Add explanatory comment to is_rvalue_or_immutable()
