Add in `contrib/debug_bootstrap.gdb` for https://gist.github.com/staticfloat/6188418
Unexport bind/TcpSocket
Rename subtype to issubtype
conv, conv2, and deconv use strided arrays
@parallel and Darray use only workers. Minor cleanup of pmap.
Fancy Mac Profiler
Don't skip frames
Use modified version of Apple's libunwind
make operators with names (e.g. colon, vcat) refer to local identifiers,
and add to Base.Operators. closes #4128
Add rounding modes to normal floating point arithmetic
Add Float32 rounding mode tests
Integrate the new rounding modes with BigFloats

This changes the old rounding mode sketch to a more intuitive one,
and using types instead of constants seems to be more logical.
Export RoundAwayZero too (even though it only works for BigFloats)
Stop hardcoding the `fenv.h` constants

As suggested by Viral in https://github.com/JuliaLang/julia/pull/3149
