Closes #11881.

This code has been copied from the original issue and updated for
modern Rust APIs.

Fixes #12910.

Apparently windows doesn't like reading from stdin with a large buffer size, and
it also apparently is ok with a smaller buffer size. This changes the reader
returned by stdin() to return an 8k buffered reader for stdin rather than a 64k
buffered reader.

Apparently libuv has run into this before, taking a peek at their code, with a
specific comment in their console code saying that "ReadConsole can't handle big
buffers", which I presume is related to invoking ReadFile as if it were a file
descriptor.

Closes #13304

Few places where previous version of tidy script cannot find XXX:
* inside one-line comment preceding by a few spaces;
* inside multiline comments (now it finds it if multiline comment starts
on the same line with XXX).

Change occurences of XXX found by new tidy script.

Closes #13360

This is an optimization which is quite impactful for compiling small crates.
Reading libstd's metadata takes about 50ms, and a hello world before this change
took about 100ms (this change halves that time).

Recent changes made it such that this optimization wasn't performed, but I think
it's a better idea do to this for now. See #10786 for tracking this issue.

When linking, all crates in the local CStore are used to link the final product.
With #[phase(syntax)], crates want to be omitted from this linkage phase, and
this was achieved by dumping the entire CStore after loading crates. This causes
crates like the standard library to get loaded twice. This loading process is a
fairly expensive operation when dealing with decompressing metadata.

This commit alters the loading process to never register syntax crates in
CStore. Instead, only phase(link) crates ever make their way into the map of
crates. The CrateLoader trait was altered to return everything in one method
instead of having separate methods for finding information.

This separate crate cache is one factor which is causing libstd to be loaded
twice during normal compilation. The crates loaded for syntax extensions have a
separate cache than the crates loaded for linking, so all crates are loaded once
per #[phase] they're tagged with.

This removes the cache and instead uses the CStore structure itself as the cache
for loaded crates. This should allow crates loaded during the syntax phase to be
shared with the crates loaded during the link phase.

Closes #4293

This appears to be causing the BSD bots to lock up when looking at the core
dumps I've managed to get. Dropping the `FileDesc` structure triggers the `Arc`
it's contained in to get cleaned up, invoking free(). This instead just closes
the file descriptor (the arc itself is never cleaned up).

I'm still not entirely sure why this is a problem because the pthreads runtime
should register hooks for fork() to prevent this sort of deadlock, but perhaps
that's only done on linux?

Rebasing of #12304.

Add requirements of TotalEq and TotalOrd

Clarify that TotalEq needs an underlying equivalence relation and that TotalOrd
needs a total ordering and specifically named the required (and sufficient)
attributes.

This test relies on the parent to be descheduled before the child sends its
data. This has proved to be unreliable on libnative on the bots. It's a fairly
trivial test regardless, so ignoring it for now won't lose much.

This also makes the listener struct sendable again by explicitly putting the
Send bound on the relevant Rtio object.

cc #13352

This has to be the most pathetic pull request I've ever made, but the `[` in `#![some_attribute]` was not getting highlighted in KATE.

`Reader`, `Writer`, `MemReader`, `MemWriter`, and `MultiWriter` now work with `Vec<u8>` instead of `~[u8]`. This does introduce some extra copies since `from_utf8_owned` isn't usable anymore, but I think that can't be helped until `~str`'s representation changes.

This should make BSD use the proper GNU make.

Broken on BSD. #12460

There's a little more allocation here and there now since
from_utf8_owned can't be used with Vec.

In the error message for when a private field is used, include the name of the struct, or if it's a struct-like enum variant, the names of the variant and the enum.

This fixes #13341.
