Deprecate the Solaris/SPARC, Solaris/x64, and Linux/SPARC ports, with the
intent to remove them in a future release.


  - Enhance the build system to issue an error message when an attempt is
    made to configure a build for one of the deprecated ports.  The error
    message will be suppressible via a new configuration option.

  - Mark the ports, and related port-specific features, as deprecated for
    removal in the relevant JDK documentation.


It is not a goal of this JEP to change the status of the affected ports
in any prior release.  The earliest release to which this JEP could be
targeted is JDK 14.


Dropping support for these ports will enable contributors in the OpenJDK
Community to accelerate the development of new features that will move
the platform forward.


### Build-configuration changes

An attempt to configure a Solaris and/or SPARC build will produce the
following output:

    $ bash ./configure
    checking compilation type... native
    configure: error: The Solaris and SPARC ports are deprecated and may be removed in a future release. \
    Use --enable-deprecated-ports=yes to suppress this error.
    configure exiting with result code 1

The new build-configuration option `--enable-deprecated-ports=yes` will
suppress the error and continue:

    $ bash ./configure --enable-deprecated-ports=yes
    checking compilation type... native
    configure: WARNING: The Solaris and SPARC ports are deprecated and may be removed in a future release.
    Build performance summary:
    * Cores to use:   32
    * Memory limit:   96601 MB

    The following warnings were produced. Repeated here for convenience:
    WARNING: The Solaris and SPARC ports are deprecated and may be removed in a future release.

The error/warning will be issued when configuring a build for Solaris and SPARC (including Solaris/SPARC, Solaris/x64, Linux/SPARC).

### Solaris-specific features deprecated for removal

* The OracleUcrypto JCE Provider in the `jdk.crypto.ucrypto` module
* The `jdk.net.SocketFlow` [socket option][SocketFlow]


Just as with [JEP 291 (Deprecate the CMS Garbage Collector)][j291] and
[JEP 335 (Deprecate the Nashorn JavaScript Engine)][j335], an alternative
is for a set of credible developers to express a clear desire to maintain these
ports going forward.  If that happens before this JEP is integrated then this
JEP can be withdrawn.  If that happens after this JEP is integrated, but before
the ports are removed, then a follow-on JEP can revert the deprecation.

[j291]: https://openjdk.java.net/jeps/291
[j335]: https://openjdk.java.net/jeps/335
[SocketFlow]: https://docs.oracle.com/en/java/javase/13/docs/api/jdk.net/jdk/net/SocketFlow.html

I would be willing to take up maintainership for the SPARC port as we're still using Linux/SPARC in Debian.
