- remove /usr/include from the include path since the iOS SDK provides the correct version
- `_NSGetEnviron()` is private and not available on iOS
- `.align` without an argument is not allowed with the Apple tools. 2^2 should be the default alignment
- ignore error messages for XCode < 5
- pass include path to libuv
There were a few ambiguous error messages which look like they could have
cropped up from either the rust compiler for the format string parser. To
differentiate, the prefix 'invalid format string' is now added in front of all
format string errors.

According to apple's documentation of rpath semantics, `@executable_path` means
that the path is relative the the *process executable*, not necessarily the
library in question. On the other hand, `@loader_path` is the path that points to
the library which contains the `@loader_path` reference. All of our rpath usage is
based off the library or executable, not just the executable. This means that on
OSX we should be using `@loader_path` instead of `@executable_path` to achieve the
same semantics as linux's $ORIGIN.
The purpose of this is to unblock the current snapshot from landing. It appears that because we were propagating linker arguments we never saw this before. Now that we're no longer printing linker arguments, we're depending on the libraries to resolve their own references. In using `@executable_path` on OSX, libraries in different locations than the executable were not able to resolve their references (because their rpaths listed were all relative to the location of the library, not the executable).
I'm still a little unclear on how this ever passed locally on my own machine, but it's clear why this is failing on the bots at least.

This binds to the appropriate pthreads_* and Windows specific functions
and calls them from Rust. This allows for removal of the C++ support
code for threads.
This needs to be reviewed for the Windows parts, I've tested on OS X and Linux.

Right now if you're running a program with its output piped to some location and
the program decides to go awry, when you kill the program via some signal none
of the program's last 4K of output will get printed to the screen. In theory the
solution to this would be to register a signal handler as part of the runtime
which then flushes the output stream.
I believe that the current behavior is far enough from what's expected that we
shouldn't be providing this sort of "super buffering" by default when stdout
isn't attached to a tty.
This isn't quite as fancy as the struct in #9913, but I'm not sure we should be exposing crate names/hashes of the types. That being said, it'd be pretty easy to extend this (the deterministic hashing regardless of what crate you're in was the hard part).
The snapshot just failed due to a debuginfo test failing, and according to its
output at
http://buildbot.rust-lang.org/builders/snap3-linux/builds/564/steps/test/logs/stdio
it appears to be because the printed lines has a little less information than
the original lines were checking for. I would suspect that this is just because
of a slightly different version of gdb, but it's not that serious regardless.

This fleshes out the io::file module a fair bit more, adding all of the functionality that I can think of that we would want. Some questions about the representation which I'm curious about:
* I modified `FileStat` to be a little less platform-agnostic, but it's still fairly platform-specific. I don't want to hide information that we have, but I don't want to depend on this information being available. One possible route is to have an `extra` field which has all this os-dependent stuff which is clearly documented as it should be avoided.
* Does it make sense for directory functions to be top-level functions instead of static methods? It seems silly to import `std::rt::io::file` and `std::rt::io::File` at the top of files that need to deal with directories and files.
This renames the `file` module to `fs` because that more accurately describes
its current purpose (manipulating the filesystem, not just files).
Additionally, this adds an UnstableFileStat structure as a nested structure of
FileStat to signify that the fields should not be depended on. The structure is
currently flagged with #[unstable], but it's unlikely that it has much meaning.

This file did not respect the #[link(name = "...")] attribute when it was
clearly intended to do so. The problem is that the crate attributes just weren't
passed in. This causes lots of problems in rust today because the object file
for all our libraries is inferred to be 'lib.o' because all of the files are
called 'lib.rs'.
I tried to figure out a good way to test for this, but I wasn't able to come up
with a good way that fit into our current testing framework. Nonetheless, I have
tested this locally and object files get named as they should. This should fix
compiling with `make -jN` again (because the object files are all different
again).

This adds bindings to the remaining functions provided by libuv, all of which
are useful operations on files which need to get exposed somehow.
Some highlights:
* Dropped `FileReader` and `FileWriter` and `FileStream` for one `File` type
* Moved all file-related methods to be static methods under `File`
* All directory related methods are still top-level functions
* Created `io::FilePermission` types (backed by u32) that are what you'd expect
* Created `io::FileType` and refactored `FileStat` to use FileType and
FilePermission
* Removed the expanding matrix of `FileMode` operations. The mode of reading a
file will not have the O_CREAT flag, but a write mode will always have the
O_CREAT flag.

This commit moves all thread-blocking I/O functions from the std::os module.
Their replacements can be found in either std::rt::io::file or in a hidden
"old_os" module inside of native::file. I didn't want to outright delete these
functions because they have a lot of special casing learned over time for each
OS/platform, and I imagine that these will someday get integrated into a
blocking implementation of IoFactory. For now, they're moved to a private module
to prevent bitrot and still have tests to ensure that they work.
I've also expanded the extensions to a few more methods defined on Path, most of
which were previously defined in std::os but now have non-thread-blocking
implementations as part of using the current IoFactory.
The api of io::file is in flux, but I plan on changing it in the next commit as
well.
Closes#10057
The invocation for making a directory should be able to specify a mode to make
the directory with (instead of defaulting to one particular mode). Additionally,
libuv and various OSes implement efficient versions of renaming files, so this
operation is exposed as an IoFactory call.
