Previously, any package would match any other package ID when searching
using the rust_path_hack, so long as the directory had one or more crate
files in it. Now, rustpkg checks that the parent directory matches the
package ID.

This can cause unexpected errors in the runtime when done while
scheduler threads are still initializing. Required some restructuring
of the main_args functions in our libraries.

Treating a package as the thing that can have other packages depend on it,
and depends on other packages, was wrong if a package has more than one
crate. Now, rustpkg knows about dependencies between crates in the same
package. This solves the problem reported in #7879 where rustpkg wrongly
discovered a circular dependency between thhe package and itself, and
recursed infinitely.
Closes #7879

@catamorphism says he has a fix coming soon, so I didn't allocate an issue for
it. If it festers for more than a few days I'll open something up though.

This will initialize a new workspace.

For some reason, I thought it wasn't necessary to write the package_id
attribute (which rustc's filesearch checks when searching for a package)
if the package ID had a single component (like "foo") as opposed to multiple
components (like "foo/bar/quux"). This meant that
`extern mod quux = "an-awesome-library";` didn't work, even if an-awesome-library
existed in the RUST_PATH.
Fixed it.

This is a series of patches to modernize option and result. The highlights are:
* rename `.unwrap_or_default(value)` and etc to `.unwrap_or(value)`
* add `.unwrap_or_default()` that uses the `Default` trait
* add `Default` implementations for vecs, HashMap, Option
* add `Option.and(T) -> Option<T>`, `Option.and_then(&fn() -> Option<T>) -> Option<T>`, `Option.or(T) -> Option<T>`, and `Option.or_else(&fn() -> Option<T>) -> Option<T>`
* add `option::ToOption`, `option::IntoOption`, `option::AsOption`, `result::ToResult`, `result::IntoResult`, `result::AsResult`, `either::ToEither`, and `either::IntoEither`, `either::AsEither`
* renamed `Option::chain*` and `Result::chain*` to `and_then` and `or_else` to avoid the eventual collision with `Iterator.chain`.
* Added a bunch of impls of `Default`
* Added a `#[deriving(Default)]` syntax extension
* Removed impls of `Zero` for `Option<T>` and vecs.

While usage of change_dir_locked is synchronized against itself, it's not
synchronized against other relative path usage, so I'm of the opinion that it
just really doesn't help in running tests. In order to prevent the problems that
have been cropping up, this completely removes the function.
All existing tests (except one) using it have been moved to run-pass tests where
they get their own process and don't need to be synchronized with anyone else.
There is one now-ignored rustpkg test because when I moved it to a run-pass test
apparently run-pass isn't set up to have 'extern mod rustc' (it ends up having
linkage failures).

As per rustpkg.md, rustpkg now builds in a target-specific
subdirectory of build/, and installs libraries into a target-specific
subdirectory of lib.
Closes #8672

Testing this is a little tricky as an intermediate temporary directory is only used for remote git repositories and therefore that path cannot be reliably exercised in the tests.
|
|
Install to the first directory in the RUST_PATH if the user set a
RUST_PATH. In the case where RUST_PATH isn't set, the behavior
remains unchanged.

Package IDs can now refer to a subdirectory of a particular source
tree, and not just a top-level directory with a src/ directory as its
parent.
For example, referring to the package ID a/b/c/d , in workspace W,
if W/src/a is a package, will build the sources for the package in
a/b/c/d (and not other crates in W/src/a).
Closes #6408

rustpkg now accepts most of rustc's command-line arguments and passes
them along to rustc when building or installing.
A few rarely-used arguments aren't implemented yet.
rustpkg doesn't support flags that don't make sense with rustpkg
(for example, --bin and --lib, which get inferred from crate file names).
Closes #8522

rustpkg now uses the workcache library to avoid recompilation.
Hooray!

A [dialogue](https://github.com/mozilla/rust/pull/8909#discussion-diff-6102725) on PR #8909 inspired me to make this change.
r? anyone
(It is possible that `std::path` itself will soon be replaced with a new implementation that kballard's working on, as mentioned in the dialogue linked above, but this revision is simple enough that I figured I'd offer it up.)

In most cases this involved removing a ~str allocations or clones
(yay), or coercing a ~str to a slice. In a few places, I had to bind
an intermediate Path (e.g. path.pop() return values), so that it would
live long enough to support the borrowed &str.
And in a few places, where the code was actively using the property
that the old API returned ~str's, I had to put in to_owned() or
clone(); but in those cases, we're trading an allocation within the
path.rs code for one in the client code, so they neutralize each
other.

This commit adds a rustpkg flag, --rust-path-hack, that allows
rustpkg to *search* inside package directories if they appear in
the RUST_PATH, while *building* libraries and executables into a
different target directory.
This behavior is hidden behind a flag because I believe we only
want to support it temporarily, to make it easier to port servo to
rustpkg.
This commit also includes a fix for how rustpkg fetches sources
from git repositories -- it uses a temporary directory as the target
when invoking `git clone`, then moves that directory into the workspace
if the clone was successful. (The old behavior was that when the
`git clone` failed, the empty target directory would be left lying
around anyway.)

This overhauls `std::run` to instead run on top of libuv. This is *not* in a mergeable state, I've been attempting to diagnose failures in the compiletest suite. I've managed to find a fair number of bugs so far, but I still don't seem to be done yet.
Notable changes:
* This requires upgrading libuv. From the discussion on #6567, I took libuv master from a few days ago, applied one patch to fix process spawning with multiple event loops in libuv, and pushed to my own fork
* The build system for libuv has changed since we last used it. There's some extra checkout from a google build system which apparently does all the magic if you don't want to require autotools, and the google system just requires python. I updated the Makefile to get this build system and build libuv with it instead. This is untested on windows and arm, and both will probably need to see some improvement.
* This required adding some pipe bindings to libuv as well. Currently the support is pretty simple and probably completely unsafe for pipes, but you at least get read/write methods. This is necessary for capturing output of processes.
* I didn't redesign `std::run` at all, I simply tried to reimplement all the existing functionality on top of libuv. Some functions ended up dying, but nothing major. All uses of `std::run` in the compiler still work just fine.
I'm not quite sure how the rest of the runtime deals with this, but I marked process structures as `no_send` because the waiting/waking up has to happen in the same event loop right now. If processes start migrating between event loops then very bad things can happen. This may be what threadsafe I/O would fix, and I would be more than willing to rebase on that if it lands first.
Anyway, for now I wanted to put this up for review, I'm still investigating the corruption/deadlock bugs, but this is in an *almost* workable state. Once I find the bugs I'll also rebase on the current master.

`rustpkg build` et al were only checking one directory up to see if it
was in a dir named "src". Ditch that entirely and instead check if the
cwd is descended from any of the workspace paths. Besides being more
intelligent about whether or not something is a workspace, this also
allows for package ids composed of multiple path components.
