auto merge of #8220 : luqmana/rust/arm-linux, r=cmr

Update the arm linux support some more. We had a previous patch for the RasberryPi. This adds a new target `arm-unknown-linux-gnueabi` for more general arm linux support.

Build/Host machine: x86_64 Debian testing (jessie) with the `gcc-4.4-arm-linux-gnueabi` package

Tested on targets:

- TS-7800 Feroceon (ARMv5TEJ) running Debian 7.0 wheezy
- Beaglebone black (ARMv7) running Angstrom GNU/Linux v2012.12
   - rustc flags:  `--target=arm-unknown-linux-gnueabi --linker=arm-linux-gnueabi-gcc`

- Samsung Galaxy S II (to make sure android still works)
   - rustc flags:  `--target=arm-linux-androideabi --android-cross-path=[path to standalone toolchain]`

Since not all arm devices (i.e. afaik anything older than armv6 like the ts-7800 i tested on) supported getting the tls address via the `mrc` instruction, I made it also try via the magic address the kernel maps into the address space (0xFFFF0FF0). One or the other should work (and on android it seems like both work).

Also fixes a bug where rustc would always try to invoke the android assembler for any kind of arm target.

std: Fix newsched logging truncation

The truncation needs to be done in the console logger in order
to catch all the logging output, and because truncation only matters
when outputting to the console.

Useful for SDL and possibly Android too.

auto merge of #8183 : omasanori/rust/migrate-new, r=sanxiyn

It seems that relatively new code uses `Foo::new()` instead of `Foo()` so I wrote a patch to migrate some structs to the former style.
Is it a right direction? If there are any guidelines not to use new()-style, could you add them to the [style guide](https://github.com/omasanori/rust/wiki/Note-style-guide)?
auto merge of #8289 : sfackler/rust/push_byte, r=erickt

It was previously pushing the byte on top of the string's null
terminator. I added a test to make sure it doesn't break in the future.
std: Use correct lifetime parameter on str::raw::slice_bytes

fn slice_bytes is marked unsafe since it allows violating the valid
string encoding property; but the function did also allow extending the
lifetime of the slice by mistake, since it's returning `&str`.

Use the annotation `slice_bytes<'a>(&'a str, ...) -> &'a str` so
that all uses of slice_bytes are region checked correctly.
