lang/rust: Update to 1.29.0

Up to and including Rust 1.27.x, the Rust build system shelled out to
a configure script to detect the presence and usability of libunwind.
Since Rust 1.28.0, it's using a static result in a `build.rs` file and
expects libunwind to be used. It was not the case on FreeBSD so far, so
we need a patch to this `build.rs` to disable that. We still need to
study if the FreeBSD port should use libunwind and what to do with this
patch. But this problem prevented the update to Rust 1.28.0 already, so
enough delay.

lang/rust: Add `make makesum-all-archs` target

It is a helper to ease the generation of the `distinfo` file for all the

lang/rust: Update to 1.26.0

The announcement is available on Rust blog:
https://blog.rust-lang.org/2018/05/10/Rust-1.26.html

Rust 1.25.0, used as the bootstrap compiler, contains the patch from
bdrewery@ to use the compat (non-ino64) symbols on FreeBSD 12-CURRENT.
Therefore, we don't need `old_fstat.c` and the associated machinery in
the `Makefile` anymore.

Update to 1.25.0.

- The ABI patch is no longer needed on head due to fixes being upstreamed
  to use the pre-ino64 symbols.  The ABI patch is still needed for the
  bootstrap but should be removable for 1.26.0 if it uses beta 2018-03-18.

Unbreak on i386/amd64 and update to 1.25.0-2018-02-19

- Stop using git to build as it is unmaintainable due to submodules,
  but more importantly because src/vendor is no longer bundled.  Just
  fetch the source already generated that has all dependencies bundled.
  It may be a bit slower to get updates but is far more maintainable.

  apply exactly between both versions.

lang/rust: Skip `.cargo-checksum.json` update when it's missing

Currently we need to update `.cargo-checksum.json` in several patched

GitHub instead of a proper released source archive. This change makes
`post-patch` and `do-configure` recipes fine in both cases.

lang/rust: Disable "omit frame pointers"

Before the patch, the default behavior of the compiler was to omit frame
pointers. However, even though it looks fine for the code produced
by the compiler, the compiler itself was broken. When there was a
compilation error, rustc panics to report that error. While handling
that panic, it tries to unwind the stack but fails to do so, which
results in an abort(3).

Here is an example:

    $ rustc hello.rs
    error: invalid reference to argument `0` (no arguments given)
     --> hello.rs:2:5

lang/rust: Remove the LLVM_PORT option

FTR, this option allowed to used LLVM from ports instead of building the
bundled copy.

The problem is that this combination isn't really tested upstream. This
led to regressions which are difficult to diagnose. For instance, in
Rust 1.21.0, the bundled LLVM provided a new API to query the features
supported by the target arch. The equivalent code inside Rust was
removed to use that new API. Unfortunately, building Rust 1.21.0+ with a
copy of LLVM not providing this API didn't failed but instead made that
list of CPU features empty. This resulted in the following obscure build
failure in Firefox:

    error[E0432]: unresolved import `x86::sse2`

To avoid future pain for both end users and maintainers, we decided to
remove that option. Yes, it will increase the (already long) time to
build Rust, but it should save time wasted on debugging what is not
really supported anyway.

lang/rust: Install Cargo + use bundled crates

This port now provides Cargo. This is the recommended now because Cargo
won't be provided separately in the future.

To build Cargo, we set `extended = true` in `config.toml`. As a side
effect, this flag also installs Rust source code. The port has a new
`SOURCES` option (disabled by default) to keep those sources.

As a consequence of this, `devel/cargo` is removed. Several ports
and Makefiles in Mk were updated to depend on `lang/rust` instead of
`devel/cargo`.

The other big change in this patch is the use of the bundled crates,

The main change in the port is the switch from configure+make to the

indicates:

 * where to install things;
 * which release channel to use;
 * where to find Python and llvm-config;
 * if documentation should be also built.

The build process should now honor ${MAKE_JOBS_NUMBER} instead of always
using all available CPU cores.

lang/rust: Enable on FreeBSD/aarch64 + various fixes

This port now uses an unofficial bootstrap of Rust 1.17.0 and Cargo

https://gist.github.com/dumbbell/b587da50ef014078da9e732a4331ebad

The port's Makefile was changed to:
    - allow to override the versions and directories of the bootstrap
      archives;
    - patch the bootstrap script and manifest with those
      versions/directories.

Beside changes to support FreeBSD/aarch64, the port received the
following fixes:
    - Pass python path to the configure script.
    - Fix and simplify the extraction of rust-std bootstrap by re-using
      existing variables.
    - Make sure tar(1) doesn't produce sparse file entries when it
      recreates the rust-std bootstrap because Python 2's tarfile module
      doesn't support them (PR 219842).

lang/rust, lang/rust-nightly: Generate PLIST in post-install

Several libraries have their filename computed and based on the absolute
path to source files. Therefore, we need to generate the PLIST. Rust
installer already produces manifests listing files it installs. The port
now uses those files to complete `${TMPPLIST}`.

While the port built fine in Poudriere, it failed when built directly on
the host (regular make or with portmaster(1)) or using a different tool
such as Synth. This commit fixes the build for those methods.

Handling of DOCS-specific files is also unified with normal files. This
gets rid of code duplication.

Rust may fail to build if a previous version is already installed
because the bootstrapped rustc puts "-L/usr/local/lib" at the beginning
of the linker flags. Therefore, mark rust as a CONFLICTS_BUILD with
itself.

Fix the build as a normal user by setting permissions on all directories
to 0755 [1].

Be closer to the standalone installer's file hierarchy by installing
files such as "components", "manifest-rustc" and "uninstall.sh".

Add "files/patch-src_librustc__back_target_freebsd__base.rs"
to remove "-L/usr/local/lib", "-L/usr/local/lib/gcc46" and
"-L/usr/local/lib/gcc44" from the builtin linker flags.
