Don't assume commutativity for multiplication in QR calculations. Replace ν with v. Fix multiplication with Q' from the right.
Make MersenneTwister equivalent in 32- and 64-bit architectures

As mentioned in issue #5999, reproduce the solution in 67f6fee for the MersenneTwister.

Note that users on 64-bit architectures will see their randomness change with no change in their seed.
fix #6033 and #6044

- trap errors inside timer callbacks
- protect timers from GC
- ignore uv alloc requests when handle->data==NULL
Base.Printf: get rid of unnecessary leading underscores in names.

This was briefly the way to indicate that a name was private to a
module, but we no longer do things that way.
BigFloat printf: prevent assertion errors [#5756].

Now you get stack overflow or no method errors instead, which at
least doesn't kill the process, so that's an improvement. The real
solution is to implement decoding for BigFloat and BigInt (coming).

Merge branch 'master' of https://github.com/JuliaLang/julia into jb/uvfixes
tolerate multiple calls to stop_timer
remove IdleAsyncWork, add_idle_cb, queueAsync
base/gmp.jl: define string(::BigInt) = dec(x).

The definition that used gmp_snprintf is ancient and unnecessary.

base/grisu.jl: use zero-dimensional arrays for NEG, LEN & POINT.

Since zero-dimensional arrays always have size 1, this might avoid
some bounds checks that otherwise have to be done.
Check for nonfinite numbers in abs2(::Complex)

abs2 now follows the behavior of abs in allowing Inf to dominate NaN. Ref: #5979
