num: Slightly optimize bigint
num: Migrate `~[T]` to `std::vec_ng::Vec`
Remove std::cmp::cmp2.

It isn't used anywhere and `cmp2(a, b, c, d)` is identical to
`(a, b).cmp(&(c, d))`.
Tag derived impls with #[automatically_derived]

This will enable rustdoc to treat them specially.
auto merge of #12929 : sfackler/rust/automatically-derived, r=cmr

This will enable rustdoc to treat them specially.

I also got rid of `std::cmp::cmp2`, which is isomorphic to the `TotalOrd` impl for 2-tuples and never used.
Refactored take_unwrap (libstd/option.rs)

Using pattern matching instead of is_some + unwrap
auto merge of #12924 : Florob/rust/bigint, r=alexcrichton

This is a minor optimization of the bignum module. The improvements mostly come from avoiding allocations and boundary checks. This also switches all of libnum to vec_ng::Vec.
Fix a test that was missed in the liblog PR
auto merge of #12933 : edwardw/rust/fallout, r=huonw

The same test was missed in chan/port renaming PR #12815 and was fixed in #12880:

> This was missed because it is skipped on linux and windows, and the mac bots were moving at the time the PR landed.

It seems the same happened to the liblog PR.
Asked if missing (), then asks about an anonymous function. Also added test.
getopts missing docs
auto merge of #12931 : aochagavia/rust/option-take_unwrap, r=cmr

Using pattern matching instead of is_some + unwrap
Add method Vec<T>::as_mut_ptr()
Document the Tm struct and fields
Remove AtomicFlag

fixes #12943
Doc-sprint: Document endian conversion functions
auto merge of #12937 : sinistersnare/rust/method-error-message, r=huonw

its a common (yet easily fixable) error to just forget parens at the end of getter-like methods without any arguments.

The current error message for that case asks for an anonymous function, this patch adds a note asking for either an anonymous function, or for trailing parens.

This is my first contribution! do i need to do anything else?
