libuv: Build the library within CMake

Take logic from upstream `Makefile.am` and `configure.ac` to build libuv
sources.

Update `uv.h` to include KWSys Large File Support configuration so that
consistent stream libraries are used (on AIX with XL).

Add a `cm_uv.h` header to include the CMake-provided copy of the `uv.h`
header from CMake sources.
