Currently, the parser doesn't give any context when it finds an unclosed
delimiter and it's not EOF. Report the most recent unclosed delimiter, to help
the user along.

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 general idea is to remove conditions completely from I/O, so in the meantime
remove the read_error condition to mean the same thing as the io_error condition.
Standardize the is_sep() functions to be the same in both posix and
windows, and re-export from path. Update extra::glob to use this.
Remove the usage of either, as it's going away.
Move the WindowsPath-specific methods out of WindowsPath and make them
top-level functions of path::windows instead. This way you cannot
accidentally write code that will fail to compile on non-windows
architectures without typing ::windows anywhere.
Remove GenericPath::from_c_str() and just impl BytesContainer for
CString instead.
Remove .join_path() and .push_path() and just implement BytesContainer
for Path instead.
Remove FilenameDisplay and add a boolean flag to Display instead.
Remove .each_parent(). It only had one caller, so just inline its
definition there.
Rewrite these methods as methods on Display and FilenameDisplay. This
turns
do path.with_display_str |s| { ... }
into
do path.display().with_str |s| { ... }
Add a new trait BytesContainer that is implemented for both byte vectors
and strings.
Convert Path::from_vec and ::from_str to one function, Path::new().
Remove all the _str-suffixed mutation methods (push, join, with_*,
set_*) and modify the non-suffixed versions to use BytesContainer.
Remove the old path.
Rename path2 to path.
Update all clients for the new path.
Also make some miscellaneous changes to the Path APIs to help the
adoption process.
There's currently a fair amount of code which is being ignored on unnamed blocks
(which are the default now), and I opted to leave it commented out for now. I
intend on very soon revisiting on how we perform linking with extern crates in
an effort to support static linking.
It's unclear to me why these currently aren't allowed, and my best guess is that
a long time ago we didn't strip the ast of cfg nodes before syntax expansion.
Now that this is done, I'm not certain that we should continue to prohibit this
functionality.
This is a step in the right direction towards #5605, because now we can add an
empty `std::macros` module to the documentation with a bunch of empty macros
explaining how they're supposed to be used.
