num: rm wrapping of `Float` methods as functions

The `Float` trait methods will be usable as functions via UFCS, and
we came to a consensus to remove duplicate functions like this a long
time ago.

It does still make sense to keep the duplicate functions when the trait
methods are static, unless the decision to leave out the in-scope trait
name resolution for static methods changes.

syntax: allow stmt/expr macro invocations to be delimited by [].

this is useful for macros like vec! which construct containers
Make libtime fields public
remove the cmath module

This is an implementation detail of the `f32` and `f64` modules and it
should not be public. It renames many functions and leaves out any
provided by LLVM intrinsics, so it is not a sensible binding to the C
standard library's math library and will never be a stable target.

This also removes the abuse of link_name so that this can be switched to
using automatically generated definitions in the future. This also
removes the `scalbn` binding as it is equivalent to `ldexp` when
`FLT_RADIX` is 2, which must always be true for Rust.
std: fix Cell's Show instance.

Previously it was printing the address of the Unsafe contained in the
Cell (i.e. the address of the Cell itself). This is clearly useless, and
was presumably a mistake due to writing `*&` instead of `&*`.

However, this later expression is likely also incorrect, since it takes
a reference into a Cell while other user code is executing (i.e. the
Show instance for the contained type), hence the contents should just be
copied out.
Vec::reserve_exact should not shrink

reserve_exact should not shrink according to documentation.
Reimplement Vec::push_all* with .extend

It is shorter and also fixes missed reserve call.

rebase of #12947 because I'm impatient.
Minor adjustments to the 0.10 release notes.

Mention another lint, fix a typo, and rearrange some things.

* push_all* operations should reserve capacity before pushing data to avoid unnecessary reallocations
* reserve_exact should never shrink, as specified in documentation

rand: remove (almost) all ~[]'s from Vec.

There are a few instances of them in tests which are using functions
from std etc. that still are using ~[].
rand: replace Rng.shuffle's functionality with .shuffle_mut.

Deprecates the `shuffle_mut` name in favour of `shuffle` too.

In future there will be many different types of owned
vectors/vector-likes (e.g. DST's ~[], Vec, SmallVec, Rope, ...), and so
privileging just `Vec` with the "functional" `shuffle` method is silly.
auto merge of #13177 : huonw/rust/devec-rand, r=alexcrichton

Remove ~[] from librand, rename Rng.shuffle_mut to .shuffle.
