This has no tests because it's near impossible to test -- since TestFn uses
`proc`s, they can not be cloned or tested for equality. The only way to really
test this is making sure that for a given number of shards `a`, sharding from
1 to `a` yields the complete set of tests. But `filter_tests` takes its vector
by value and `proc`s cannot be compared.

The Float trait in libstd is quite a large trait which has dependencies on cmath
(libm) and such, which libcore cannot satisfy. It also has many functions that
libcore can implement, however, as LLVM has intrinsics or they're just bit
twiddling.
This commit moves what it can of the Float trait from the standard library into
libcore to allow floats to be usable in the core library. The remaining
functions are now resident in a FloatMath trait in the standard library (in the
prelude now). Previous code which was generic over just the Float trait may now
need to be generic over the FloatMath trait.

Previously the longer hand-written usage string was never being printed:
theoretically it was trying to detect when precisely `--help` was
passed (but not `-h`), but the getopts framework was considering a check
for the presence of `-h` to be a check for that of `--help` too,
i.e. the code was always going through the `-h` path.
This changes it to print the extended usage for both `-h` and `--help`,
meaning that it does actually appear correctly.
for `~str`/`~[]`.
Note that `~self` still remains, since I forgot to add support for
`Box<self>` before the snapshot.
How to update your code:
* Instead of `~EXPR`, you should write `box EXPR`.
* Instead of `~TYPE`, you should write `Box<Type>`.
* Instead of `~PATTERN`, you should write `box PATTERN`.

A new flag to the test runner, --nocapture, can be passed to instruct that the
output of tests should not be captured by default. The behavior can also be
triggered via a RUST_TEST_NOCAPTURE environment variable being set.

The constructor for `TaskBuilder` is being changed to an associated
function called `new` for consistency with the rest of the standard
library.

This pull request:
- Merges the `Round` trait into the `Float` trait, continuing issue #10387.
- Has floating point functions take their parameters by value.
- Cleans up the formatting and organisation in the definition and implementations of the `Float` trait.
More information on the breaking changes can be found in the commit messages.
Make all of the methods in `std::num::Float` take `self` and their other parameters by value.
Some of the `Float` methods took their parameters by value, and others took them by reference. This standardises them to one convention. The `Float` trait is intended for the built in IEEE 754 numbers only so we don't have to worry about the trait serving types of larger sizes.

libstd: Implement `StrBuf`, a new string buffer type like `Vec`, and port all code over to use it.
