I added a test case which does not compile today, and required changes on
privacy's side of things to get right. Additionally, this moves a good bit of
logic which did not belong in reachability into privacy.
All of reachability should solely be responsible for determining what the
reachable surface area of a crate is given the exported surface area (where the
exported surface area is that which is usable by external crates).
Privacy will now correctly figure out what's exported by deeply looking
through reexports. Previously if a module were reexported under another name,
nothing in the module would actually get exported in the executable. I also
consolidated the phases of privacy to be clearer about what's an input to what.
The privacy checking pass no longer uses the notion of an "all public" path, and
the embargo visitor is no longer an input to the checking pass.
Currently the embargo visitor is built as a saturating analysis because it's
unknown what portions of the AST are going to get re-exported.
This also cracks down on exported methods from impl blocks and trait blocks. If you implement a private trait, none of the symbols are exported, and if you have an impl for a private type none of the symbols are exported either. On the other hand, if you implement a public trait for a private type, the symbols are still exported. I'm unclear on whether this last part is correct, but librustc will fail to link unless it's in place.

This was needed to access UEFI boot services in my new Boot2Rust experiment.
I also realized that Rust functions declared as extern always use the C calling convention regardless of how they were declared, so this pull request fixes that as well.
This implements a fair amount of the unimpl() functionality in io::native
relating to filesystem operations. I've also modified all io::fs tests to run in
both a native and uv environment (so everything is actually tested).
There are a few bits of remaining functionality which I was unable to get
working:
* truncate on windows
* change_file_times on windows
* lstat on windows
I think that change_file_times may just need a better interface, but the other
two have large implementations in libuv which I didn't want to tackle trying to
copy. I found a `chsize` function to work for truncate on windows, but it
doesn't quite seem to be working out.

Changes:
* default value when no args
* license
* removed libc printing
* use extra::bigint instead of handmade gmp binding
The drawback is that it's 2 order of magnitude slower, the good news is that there is a good bench for extra::bigint.
If a function is marked as external, then it's likely desired for use with some
native library, so we're not really accomplishing a whole lot by internalizing
all of these symbols.

* moved `extern` inside module
* changed `extern "stdcall"` to `extern "system"`
* changed `cfg(target_os="win32")` to `cfg(windows)`
* only run on Windows && x86, (not x86_64)
* updated copyright dates
There was a syntax error because the `extern "stdcall"` was outside the module instead of inside it.
* moved `extern` inside module
* change `extern "stdcall"` to `extern "system"`
* change `cfg(target_os="win32")` to `cfg(windows)`
* updated copyright dates
* changed log(error, ...) => info!(....)
* added `pub` keyword to kernel32 functions
Changes:
* add licence;
* remove usage of libc and unsafe;
* use BufferedWriter to improve performance;
* use a DummyWriter to cancel binary output in test.

This implementation of the meteor contest implements:
- insertion check with bit trick;
- pregenetation of every feasible placement of the pieces on the
board;
- filtering of placement that implies unfeasible board
- central symetry breaking
related to #2776
I've started working on this issue and pushed a small commit, which adds a range check for integer literals in `middle::const_eval` (no `uint` at the moment)
At the moment, this patch is just a proof of concept, I'm not sure if there is a better function for the checks in `middle::const_eval`. This patch does not check for overflows after constant folding, eg:
let x: i8 = 99 + 99;
