Add struct and type doc comments for extra::url::*
Add struct and type doc comments for extra::url::*

Updated doc comments further, following suggestions from huonw in PR
#10752.
Add a macro to check if logging at a given label is enabled

This is useful when the information that is needed to do useful logging
is expensive to produce.
Disallow duplicate bindings of struct fields

Closes #9725
Add test to check for debug logging disabled at compile time
Search for libfoo.a on windows as well as foo.lib

Turns out LLVM only builds libfoo.a libraries, so we're going to need this logic
to statically link librustc

Register new snapshots
auto merge of #10747 : alexcrichton/rust/snapshots, r=cmr

This registers new snapshots after the landing of #10528, and then goes on to tweak the build process to build a monolithic `rustc` binary for use in future snapshots. This mainly involved dropping the dynamic dependency on `librustllvm`, so that's now built as a static library (with a dynamically generated rust file listing LLVM dependencies).

This currently doesn't actually make the snapshot any smaller (24MB => 23MB), but I noticed that the executable has 11MB of metadata so once progress is made on #10740 we should have a much smaller snapshot.

There's not really a super-compelling reason to distribute just a binary because we have all the infrastructure for dealing with a directory structure, but to me it seems "more correct" that a snapshot compiler is just a `rustc` binary.
Fix a bug in exporting trait implementations

I used the wrong condition where I was looking for "is this method public or is
this implementation a trait" rather than what was being checked.
Fix the comments for libsyntax::parse::parser::parse_sugary_call_expr

The comments on this function date back from when it was used for `for`
expressions in addition to `do` expressions.
Improve various Vim syntax highlighting things.

- Implement comment nesting (the implementation is quite ugly at present
  and is not quite correct; note the big comment in that area).

- Highlight invalid escape sequences as errors.

- Fix up various inconsistencies and incorrectnesses in number
  highlighting.

- Update prelude items (``std::io::{Buffer, Writer, Reader, Seek}``).

- Highlight the ``proc`` keyword.

- Remove %-formatting sequence highlighting (a relic of old formatting).

- Don't highlight TODO in strings (it's unconventional).

Don't infinitely recurse in a process test

Note entirely sure how this is passing at all today, but regardless this fixes
the problems seen in #10790
Move std::util::ignore to std::prelude::drop

It's a more fitting name for the most common use case of this function.

std::str: remove from_utf8.

This function had type &[u8] -> ~str, i.e. it allocates a string
internally, even though the non-allocating version that take &[u8] ->
&str and ~[u8] -> ~str are all that is necessary in most circumstances.
std::str: s/from_utf8_slice/from_utf8/, to make the basic case shorter.
