Unsuffixed literals like 1 and 1.1, and free type parameters sometimes
have to be printed in error messages, which ended up with \<V0>, \<VI0>

into the message so it's not a completely black box.

The gamma and bessel functions are of little utility outside a small specialized subset of use cases, and so they don't really make sense for inclusion in the standard library. The only reason they were included in the first place was to mirror libm, which is not a very good justification. If people need them for their own projects then they can make their own bindings to libm (which isn't too hard).

In general, you can run "rustpkg help <cmd>" to see some specific usage information for <cmd>. However, this was handled in a very ad-hoc and buggy manner. For example, running "rustpkg help prefer" would actually show you the usage information for the "uninstall" cmd. Or "rustpkg help test" would show you the usage information for the "build" command. Or "rustpkg help list" would just run the "list" command (and not show you anything usage information)

Instead of reading a byte at a time in a loop we hardcode how to read each size.
We also try to do as few reads as possible by reading as big primitive types as
possible. For example if size is eight we do a single read of a u64 value and
if size is seven we read it as [u32|u16|u8].

So far the following code
```
struct Foo;
fn main() {
let mut t = Foo;
let ref b = Foo;
a += *b;
}
```
errors with
```
test.rs:15:3: 13:11 error: binary operation + cannot be applied to type `Foo`
test.rs:15 *a += *b;
```
Since assignment-operators are no longer expanded to ```left = left OP right``` but are independents operators it should be
```
test.rs:15:3: 13:11 error: binary operation += cannot be applied to type `Foo`
test.rs:15 *a += *b;
```
to make it clear that implementing Add for Foo is not gonna work. (cf issues #11143, #11344)
Besides that, we also need to typecheck the rhs expression even if the operator has no implementation, or we end up with unknown types for the nodes of the rhs and an ICE later on while resolving types. (once again cf #11143 and #11344).
This probably would get fixed with #5992, but in the meantime it's a confusing error to stumble upon.
@pcwalton, you wrote the original code, what do you think?
(closes #11143 and #11344)
Instead of reading a byte at a time in a loop we copy the relevant bytes into
a temporary vector of size eight. We can then read the value from the temporary
vector using a single u64 read. LLVM seems to be able to optimize this
almost scarily good.

auto merge of #11376 : alexcrichton/rust/remove-eof, r=pcwalton
This is something I have been meaning to do for awhile, but upon inspection of the `eof` method on all of the `Reader` impls you may find some interesting surprises. The method returns a good answer for almost all wrapped I/O objects (buffered readers, mem readers, util readers, etc), but the actual return value on all I/O objects themselves is almost always useless.
Almost no I/O object other than a file actually knows when it's hit EOF or not. I think that pretending that all objects know when they've hit the end when almost none do is probably a bad idea. I can't really come up with a good answer to "is this file descriptor at eof" or "is this tcp stream at eof" much less "is this udp socket at eof". Due to being unable to answer these questions for *all* readers, I believe that it shouldn't be a part of the core `Reader` trait.
