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,
instead of relying on Cargo's registry (which was part of the distfiles,

devel/cargo: Add patch to fix LibreSSL support

Cargo crashes when compiled with LibreSSL. To fix this, it needs newer
versions of some crates it depends on. See the following GitHub pull
request:
https://github.com/rust-lang/cargo/pull/3521

The registry is also recreated because of those new crates.

`PORTREVISION` is bumped to 2.

devel/cargo: Fix bootstrap checksum + use ${OPENSSLBASE}

Because devel/cargo and lang/rust-nightly use a different DISTFILE with
the same name, the wrong checksum and size was selected in devel/cargo.
To fix this, keep the parent directory (a date) in the DISTFILE name.

Also, depending on the value of DEFAULT_VERSION=ssl= and whether OpenSSL
from ports is installed, the openssl-sys crate could fail to build.
Passing OpenSSL location to make was way too complicated anyway. So
simplify it and use ${OPENSSLBASE}. This was reported in PR 216385.

Bump PORTREVISION to 1.

devel/cargo: Update to 0.15.0, enable on i386

The new version requires cargo(1) to be available. Therefore, we let the
Ports system to extract the bootstrap cargo (it was done by the Cargo
build system before) and set a configure flag to point to it.

We need to set OPENSSL_DIR as a Make environment variable because the
openssl-sys crate's build.rs doesn't know about FreeBSD.

Finally, enable devel/cargo on i386. A bootstrap cargo executable is
available for FreeBSD/i386 since last October but I missed it. We can
now use it to build a port/package for i386.

devel/cargo: Update to 0.14.0

This implicitely fixes the fact that the previous bootstrap archive
fetch was failing because it was updated from a snapshot of
0.12.0-nightly to 0.13.0-nightly, even though the same URL was used.

Cargo requires a prebuilt bootstrapped version of itself. The only one
