adding uv::direct and beginning to work out tcp request case lots of changes, here.. should've commited sooner. - added uv::direct module that contains rust fns that map, neatly, to the libuv c library as much as possible. they operate on ptrs to libuv structs mapped in rust, as much as possible (there are some notable exceptions). these uv::direct fns should only take inputs from rust and, as neccesary, translate them into C-friendly types and then pass to the C functions. We want to them to return ints, as the libuv functions do, so we can start tracking status. - the notable exceptions for structs above is due to ref gh-1402, which prevents us from passing structs, by value, across the Rust<->C barrier (they turn to garbage, pretty much). So in the cases where we get back by-val structs from C (uv_buf_init(), uv_ip4_addr(), uv_err_t in callbacks) , we're going to use *ctypes::void (or just errnum ints for uv_err_t) until gh-1402 is resolved. - using crust functions, in these uv::direct fns, for callbacks from libuv, will eschew uv_err_t, if possible, in favor a struct int.. if at all possible (probably isn't.. hm.. i know libuv wants to eventually move to replace uv_err_t with an int, as well.. so hm). - started flushing out a big, gnarly test case to exercise the tcp request side of the uv::direct functions. I'm at the point where, after the connection is established, we write to the stream... when the writing is done, we will read from it, then tear the whole thing down. overall, it turns out that doing "close to the metal" interaction with c libraries is painful (and more chatty) when orchestrated from rust. My understanding is that not much, at all, is written in this fashion in the existant core/std codebase.. malloc'ing in C has been preferred, from what I've gathered. So we're treading new ground, here!
