1fc8a2f2a4 rt: use the [u]int[nn]_t types in the RNG. 
This means that `ub4`s are always 4 bytes, rather than being 8 bytes on
x64. (Suggested but not implemented by upstream: "Porting it to a 64-bit
machine [...] may just need an adjustment of the definition of ub4")

106fd12423 rt: pull upstream ISAAC code for consistency between 32/64 bit platforms 
The "unsigned 4 byte" `ub4`s are actually 8 bytes on 64-bit platforms
which mean that some bits > 2**32 were retained in calculations, these
would then "reappear" after a shift and so the stream of random numbers
would differ on 32 bit vs 64 bit platforms.

Like I commented in #2043, I can't reproduce the weirdness from #1388 on either mac or linux (x84_64) and pushing to try gives all green.

That's 128 less bytes to have to keep in the stack for every call to __morestack.

a5ddc00982 rustc: Use an out pointer to return structs in x86 C ABI. #5347 
This Adds a bunch of tests for passing and returning structs
of various sizes to C. It fixes the struct return rules on unix,
and on windows for structs of size > 8 bytes. Struct passing
on unix for structs under a certain size appears to still be broken.

ef282dbe2a auto merge of #5409 : brson/rust/rt, r=brson 
r?

There are a lot of commits here, but not all that much substance. Mostly just refactoring.

I started sketching out the beginnings of a very simple I/O API in `core::rt::io` that represents I/O streams as a single `Stream` trait instead of `Reader` / `Writer` pairs. This seems to be the more common pattern (at least this is how the .NET BCL does it) and it seems to me that separate readers and writers would make duplex streams very awkward. Regardless, I don't intend to go very far down the I/O API design road without some mailing list discussion.

I've also started on the uv bindings for file I/O but haven't gotten very far.

Also hooked up the new scheduler to `rust_start` and the compiletest driver. 70% of run-pass test cases already pass, but I wouldn't read too much into that.

I also split the direct, low-level uv bindings in two so that the scheduler can have its own set, leaving `std::net` on its own.

6d4499ce4d auto merge of #5424 : luqmana/rust/inline-rt, r=brson 
As per #2521. Inlining seems to improve performance slightly:

                 Inlined          Not Inlined
    x86:         13.5482            14.4112
    x86_64:      17.4712            18.0696

(Average of 5 runs timed with `time`)

```Rust

fn foo() -> int {
    int::from_str(~"28098").unwrap()
}

fn main() {
    for 1000000.times {
        foo();
        foo();
        foo();
        foo();
        foo();
    }
}
```

All run on:

    Linux 3.2.0-0.bpo.4-amd64 #1 SMP Debian 3.2.35-2~bpo60+1 x86_64 GNU/Linux

The MIPS and ARM bits I didn't inline since I'm not as familiar with them and I also can't test them. All green on try.

efc7f82bc4 Revamp foreign code not to consider the Rust modes. This requires 
adjusting a few foreign functions that were declared with by-ref
mode.  This also allows us to remove by-val mode in the near future.

With copy mode, though, we have to be careful because Rust will implicitly pass
somethings by pointer but this may not be the C ABI rules.  For example, rust
will pass a struct Foo as a Foo*.  So I added some code into the adapters to
fix this (though the C ABI rules may put the pointer back, oh well).

This patch also includes a lint mode for the use of by-ref mode
in foreign functions as the semantics of this have changed.

0ad3a110be Work around linkage bug cross-compiling from x86_64-apple-darwin to i686-apple-darwin 
The correct opendir/readdir to use appear to be the 64-bit versions called
opendir$INODE64, etc. but for some reason I can't get them to link properly
on i686. Putting them in librustrt and making gcc figure it out works.
This mystery will have to wait for another day.

20fd0c53ed auto merge of #4938 : thestinger/rust/no_zero, r=brson 
I removed the unused wrappers methods named `calloc` because they relied on the malloc wrapper having a `bool zero = true` default parameter (which resulted in some accidental zeroing). Perhaps wrapping the actual calloc function would be useful, but I don't know of an existing use case that could use it so I just removed these.

This gives an ~1% performance improvement for TreeMap, which does a lot of small allocations. Vectors use `realloc` which didn't zero before these changes so there's no measurable change in performance.

cf1c3d2da0 polymorphic indexed_list fixes: 
1) indexed_list no longer has virtual methods. It's not actually subclassed
and there is very rarely good reason to subclass collection classes.
2) Added a virtual dtor to indexed_list_object which is intended to be
subclassed. This allows derived dtors to be called if the object is
deleted with a indexed_list_object*.

8adacc06aa Some isaac_ssed fixes: 
1) Check for eof (shouldn't happen, but if it does we'll fall into an
infinite loop).
2) Use fatal instead of assert (will work if NDEBUG is ever defined
and provides better diagnostics).
3) Ignore errors from close since they shouldn't matter.

Closes #3679.

68e755b1c2 core: Allocate threads on demand, not on scheduler startup 
API change: rust_kernel::create_scheduler() or
rust_scheduler::rust_scheduler() respecitevly now take ownership of the
launch factory argument, it is needed to create new threads on demand.

Also renames rustrt::sched_threads() to rustrt::rust_sched_threads() for
consistency. Added rustrt::rust_max_sched_threads() to return the
maximal number of scheduled threads of the current scheduler.

Fixes #3493.

3f0d207b32 gc: Add stack walker for new garbage collector. 
Safe points are exported in a per-module list via the crate map. A C
runtime call walks the crate map at startup and aggregates the list of
safe points for the program.

Currently the GC doesn't actually deallocate memory on malloc and
free. Adding the GC at this stage is primarily of testing value.

The GC does attempt to clean up exchange heap and stack-allocated
resource on failure.

A result of this patch is that the user now needs to be careful about
what code they write in destructors, because the GC and/or failure
cleanup may need to call destructors. Specifically, calls to malloc
are considered unsafe and may result in infinite loops or segfaults.

6c6a47bf22 std: splitting out tcp server API + tests 
- we now have two interfaces for the TCP/IP server/listener workflow,
based on different user approaches surrounding how to deal with the
flow of accept a new tcp connection:

1. the "original" API closely mimics the low-level libuv API, in that we
have an on_connect_cb that the user provides *that is ran on the libuv
thread*. In this callback, the user can accept() a connection, turning it
into a tcp_socket.. of course, before accepting, they have the option
of passing it to a new task, provided they *make the cb block until
the accept is done* .. this is because, in libuv, you have to do the
uv_accept call in the span of that on_connect_cb callback that gets fired
when a new connection comes in. thems the breaks..

I wanted to just get rid of this API, because the general proposition of
users always running code on the libuv thread sounds like an invitation
for many future headaches. the API restriction to have to choose to
immediately accept a connection (and allow the user to block libuv as
needed) isn't too bad for power users who could conceive of circumstances
where they would drop an incoming TCP connection and know what they're
doing, in general.

but as a general API, I thought this was a bit cumbersome, so I ended up
devising..

2. an API that is initiated with a call to `net::tcp::new_listener()` ..
has a similar signature to `net::tcp::listen()`, except that is just
returns an object that sort of behaves like a `comm::port`. Users can
block on the `tcp_conn_port` to receive new connections, either in the
current task or in a new task, depending on which API route they take
(`net::tcp::conn_recv` or `net::tcp::conn_recv_spawn` respectively).. there
is also a `net::tcp::conn_peek` function that will do a peek on the
underlying port to see if there are pending connections.

The main difference, with this API, is that the low-level libuv glue is
going to *accept every connection attempt*, along with the overhead that
that brings. But, this is a much more hassle-free API for 95% of use
cases and will probably be the one that most users will want to reach for.

Jeff Olson
8769409612 rt: adding rust_uv_* binding for kernel malloc and free'ing :/ 
I need these in the context of doing various malloc/free operations for
libuv structs that need to live in the heap, because of API workflow
(there's no stack to put them in). This has cropped up several times
when impl'ing the high-level API for things like timers, but I've decided
to take the plunge and use this approach for the net::tcp module.

Technically, this can be avoided by spawning a new
task that contains the needed memory structures on its stack and then
having it block for the duration of the time we need that memory to be
valid (this is what I did in std::timer). Exposing this API provides a
much lower overhead way to address
the issue, albeit with safety concerns. The main mitigation policy should
be to use malloc/free with libuv handles only when the handles, are then
associated with a resource or class-with-dtor. So we have a finite lifetime
for the object and can gaurantee a free(), barring a runtime crash (in
which case you have bigger problems!)
