Don't assume commutativity for multiplication in QR calculations. Replace ν with v. Fix multiplication with Q' from the right.
call _init() in modules at init time. closes #1268
Merge branch 'master' of github.com:JuliaLang/julia into jb/module_init
rename _init to __init__
better module initialization order: init inner modules after outer modules
are complete and initialized.
fix #5963
Revert "fix #5963"

This reverts commit df0921b50ca50a27fe8495935810105c41476043.
Redirect stderr from which

This avoids `which: no fetch in ($PATH)` messages when downloading dependencies. These can get pretty long.
Add quotes and an informative error message

Since [ -x  ] is true, but [ -x "" ] is false
Alternative fix for #3567

As discussed in #5825, this puts handles that should be preserved into a global ObjectIdDict. The only slightly sketchy parts are the idle and async worker invocations which I'll have to think about (we don't have a good interface for them yet, really), but it's not as simple as just putting a wait() based interface on top, since people are using them for synchronization with threaded C libraries.

Fix two small bugs in process handling with new libuv.

First, I forgot the finalizer (my bad). The second issue is slightly
more subtle which is that we now destroy process objects earlier, so
libuv might actually get a SIGCHLD. We have a custom patch that
disables signals while in fork, which also happended to block SIGCHLD
because it was in the wrong place. The associated libuv commit fixes
that.

call __init__() in modules at init time
Better fix for #4366

- Instead of throwing DomainError for besselj(n, x) when
  n>typemax(Int32), call besselj(float64(n), x) instead.
- Fixes also wraparound for n<typemin(Int32).

The behavior for n::Int is now symmetric and complements the runtime
dispatch behavior for n::FloatingPoint.
