Removed remnants of `@mut` and `~mut` from comments and the type system.
Completed patch searching for rust docs
Made temporary changes to include multiple keywords in rustdoc search

Implemented search based on multiple keywords

Added some commenting and house cleaning

Added path searching to rustdoc
Update .po and strip down untranslated entries.

This work is done by execute these commands manually:

$ po4a --copyright-holder="The Rust Project Developers" \
    --package-name="Rust" \
    --package-version="0.10-pre" \
    -M UTF-8 -L UTF-8 \
    doc/po4a.conf
$ for f in doc/po/**/*.po; do
>   msgattrib --translated $f -o $f.strip
>   if [ -e $f.strip ]; then
>       mv $f.strip $f
>   else
>       rm $f
>   fi
> done

It should be managed by the build system automatically to use in our
translation workflow, but I've not yet done that.

Temporary change to issue #10535. Requires significant re-factoring to search completely based on the index paths. For example searching for "File::" in this fix will return no results. Still need to search completely based on path (rather than name's + types) to completely fix. Will continue to work this
Add noalias and noreturn attributes in more cases.

At least one mostly-translated (over 80% translation rate) document is needed to test the translation workflow, so I'll working on Japanese translation.
Fix the representation of C void pointers in LLVM IR

Currently, we have c_void defined to be represented as an empty struct,
but LLVM expects C's void* to be represented as i8*. That means we
currently generate code in which LLVM doesn't recognize malloc() and
free() and can't apply certain optimization that would remove calls to
those functions.

Renamed LIBDIR_RELATIVE to CFG_LIBDIR_RELATIVE
add an experimental tag for Gc<T> due to cycles

This type isn't yet very useful since it only pretends cycles won't be
a problem. Anyone using it should be made aware that they're going to
leak.
auto merge of #11521 : dguenther/rust/hide_libdir_relative, r=alexcrichton

Renamed `LIBDIR_RELATIVE` to `CFG_LIBDIR_RELATIVE`. It's not a configurable variable, but it looks out of place without the `CFG_` prefix.

std::trie: add benchmarks for insert.
std::trie: optimise insert slightly.

This reduces the number of moves/memcpy's we do, which makes insert
faster, especially in cases of keys with long equal prefixes (the
_low_bits tests):

Before:

    bench_insert_large                ... bench:    553966 ns/iter (+/- 64050)

remove reference counting headers from ~

Unique pointers and vectors currently contain a reference counting
header when containing a managed pointer.

This `{ ref_count, type_desc, prev, next }` header is not necessary and
not a sensible foundation for tracing. It adds needless complexity to
library code and is responsible for breakage in places where the branch
has been left out.

The `borrow_offset` field can now be removed from `TyDesc` along with
the associated handling in the compiler.
