add hist2d function (2-dimensional histogram)
Update logdet. Close #3070.
Update .travis.yml configuration in the manual.
Use Number instead of Integer in some linalg operations
added isela function, removed redundant functions: isinteger, isreal, iscomplex, isbool.
renamed integer_valued, real_valued, float64_valued
Merge pull request #3052 from daviddelaat/linalgnumber

RFC: Use Number instead of Integer in some linalg operations
=== fallback can now replace == definitions for basic integer types
a couple other equality-related fixes:
  !isequal(-0.0f0, 0.0)
  signbit() for BigFloat, make BigFloat isequal() work
  == and isequal for Ranges

clean up fpiseq and fpislt intrinsics a bit
fix conversion of -0.0 to Uint
rename isinteger/realvalued -> isinteger/real, isela -> iseltype
fix #3018 and update windows build instructions (closes #3049) to avoid gcc/openblas compile bugs
fix corner case of iround(prevfloat(0.5))
Merge branch 'master' of github.com:JuliaLang/julia
Update README.windows.md formatting

WINDOWS: fix win32 build and tests
remove a couple more redundant intrinsics
a bit more about isequal() and floats in the manual
Shut down all named pipes and tcp streams in jl_close_uv.
Add a test for shutdown being called twice.  Unfortunately it hangs rather than fails.
Stop using libuv's flags, check in jl_close_uv if close has already been called from julia
Change is_open to isopen
