make util::NonCopyable a unit struct instead of a struct with a unit
remove bitrotted cant_nest field from RWARC (the #[mutable] tag suffices)
Document unstable::atomics fetch_* return values
Thread order_lock through rwlock condvars for reacquiring access_lock. Fixes #7065.
Add a test case for #7065.
Change sync::RWlock implementation to use atomic uint instead of exclusive, for performance. Close #7066.
Improve comments in sync and arc a bit more.

syntax: correct the Rand::rand call to select enum variants in #[deriving(Rand)].

Previously, this was not a global call, and so when `#[deriving(Rand)]`

Also, fix a minor inconsistency between uints and u32s for this piece
of code.
syntax: revert the uint -> u32 "fix"; make the names/comment match.
xfail test on windows, because extern mod doesn't work there
update the libstd docstring for the rename
