Auto merge of #8453 - sourcefrog:name-length-limit-8452, r=alexcrichton
Write GNU tar files, supporting long names.
Fixes #8452
If I understand the previous bugs correctly, long trees packaged using Cargo with this patch will be misinterpreted by Cargo from before Jan 2016. (Without this patch, they can't be written at all.)
To me that seems like long enough ago that it's safe to land this now.
Auto merge of #8446 - ehuss:fix-usize-32, r=alexcrichton
Fix overflow error on 32-bit.
This fails to compile on 32-bit platforms with an overflow error ("attempt to shift right by 32_i32 which would overflow").
I think it would be highly unlikely for any value to be in the billions. Alternatively it can be rewritten to something like `assert!(val <= u32::MAX as usize);`.
Exclude the target directory from backups using CACHEDIR.TAG
This patch follows the lead of #4386 (which excludes target directories
from Time Machine backups) and is motived by the same reasons listen
in #3884. CACHEDIR.TAG is an OS-independent mechanism supported by Borg,
restic, GNU Tar and other backup/archiving solutions.
See https://bford.info/cachedir/ for more information about the
specification. This has been discussed in Rust Internals earlier this
year[1] and it seems like it's an uncontroversial improvement so I went
ahead with the patch.
One thing I'm wondering is whether this should maybe cover the whole main target directory (right now it applies to `target/debug`, `target/release` etc. but not to target root).

This is following the discussion on GitHub. The doc tests are no longer
necessary because Layout::new() creates CACHEDIR.TAG directly in target

Cut down on data fetch from git dependencies
Currently Cargo pretty heavily over-approximates data fetch for git
dependencies. For the index it fetches precisely one branch, but for all
other git dependencies Cargo will fetch all branches and all tags all
the time. In each of these situations, however, Cargo knows if one
branch is desired or if only one tag is desired.
This commit updates Cargo's fetching logic to plumb the desired

determine what to fetch. Namely if a branch or tag is explicitly
selected then we only fetch that one reference from the remote, cutting
down on the amount of traffic to the git remote.
Additionally a bugfix included here is that the GitHub fast path for
checking if a repository is up-to-date now works for non-`master`-based

ensure that if we have a locked revision that we plumb the desired

`Rev` very early on, but the fetching logic for `Rev` is very eager and

Some LTO fixes.
This reworks the LTO computation a little to address a few issues:
- `cargo build` in a project with both a lib and bin would not engage the optimization introduced in #8192 where the lib *should* be compiled with `-C linker-plugin-lto` (bitcode only). This happened because the old code was starting root units as `Lto::None`. The solution here is to conditionally choose the starting Lto for roots.
- A project with a dylib dependency would fail to build. It was building the dylib with `-C linker-plugin-lto` which is not valid.
- A project with a bin/lib would build the lib differently based on whether or not it was selected. This changes it so that the lib is built the same. See `lto::between_builds`, where the second build the lib is now fresh.
- Tests/benchmarks of a `lib` target will now support LTO.
- Treats example libs a little more consistently as regular libs.
I scattered some comments throughout, hopefully it's not too difficult to follow.
