This will help not to meet confusing errors.
In issue #5873, the error was "expected constant expr for vector length: Can't cast str to int".
It was originally "expected constant expr for vector length: Non-constant path in constant expr" (though still invalid error).
This patch make the original error to be printed.
This patch is a sledge hammer that moves all tests into `#[cfg(test)] mod test { .. }`, and makes them private, there were several instances of `pub mod tests { #[test] pub fn ... } `.
(The reason for this is I was playing with using `syntax` to index code ([result so far](http://www.ug.it.usyd.edu.au/~hwil7821/rust-api/)) and it was getting some junk from the tests.)
The rustdoc commit is particularly brutal, so it's fine if that one isn't landed.
In order to do a context switch you have to give up ownership of the scheduler,
effectively passing it to the next execution context. This could help avoid
some situations here tasks retain unsafe pointers to schedulers between context
switches, across which they may have changed threads.
There are still a number of uses of unsafe scheduler pointers.
This adds examples for the methods in std::base64.
Each example is complete in the sense that you can copy-paste it into a file and compile it successfully without adding anything (imports, etc). The hardest part of figuring out how to use this was figuring out the right import statements to put at the top.

Pulled out tests into their own modules inside the files they test,
as per the draft style guidelines.
Started a new module, path_util, for utility functions to do with
paths and directories.
Changed default_dest_dir to use a condition and return Path
instead of Option<Path>.
Closes#5487, #1913, and #4568
I tracked this by adding all used unsafe blocks/functions to a set on the `tcx` passed around, and then when the lint pass comes around if an unsafe block/function isn't listed in that set, it's unused.
I also removed everything from the compiler that was unused, and up to stage2 is now compiling without any known unused unsafe blocks.
I chose `unused_unsafe` as the name of the lint attribute, but there may be a better name...

This takes care of one of the last remnants of assumptions about enum layout. A type visitor is now passed a function to read a value's discriminant, then accesses fields by being passed a byte offset for each one. The latter may not be fully general, despite the constraints imposed on representations by borrowed pointers, but works for any representations currently planned and is relatively simple.
Closes#5652.
Update an old test to pass. I'm not 100% sure what the intent of the test was, but it's hard to see how I could have corrupted the intent of the test from the tiny changes I made.
This is a follow-up to #5761. Its purpose is to make core::libc more consistent - it currently only defines SIGKILL and SIGTERM, because they are the only values that happen to be needed by libcore.
This adds all the posix signal value constants, except for those that have different values on different architectures.
The output of the command `man 7 signal` was used to compile these signal values.
