Move netmgr/uv-compat.h to <isc/uv.h>

As we are going to use libuv outside of the netmgr, we need the shims to
be readily available for the rest of the codebase.

Move the "netmgr/uv-compat.h" to <isc/uv.h> and netmgr/uv-compat.c to
uv.c, and as a rule of thumb, the users of libuv should include
<isc/uv.h> instead of <uv.h> directly.

Additionally, merge netmgr/uverr2result.c into uv.c and rename the
single function from isc__nm_uverr2result() to isc_uverr2result().
