6106c2c21c package/openjdk{-bin}: add OpenJDK25 and configure it as latest
OpenJDK 25 is the latest release.
See: https://endoflife.date/oracle-jdk

- BR2_OPENJDK_VERSION_LATEST is now set to 25.

- Add version-specific patches for 25.0.2+10:
  - 0001: Add ARCv2 ISA processors support to Zero
  - 0002: Compile OpenJDK in headless mode without requirements
  - 0003: Fix ambiguous cmp() overload in aarch64 macro assembler
          (older GCC 6.x compatibility)
  - 0004: Fix constexpr on non-literal type in Shenandoah GC
          (older GCC 6.x compatibility)

- Add -fpermissive to fix template definition error with older GCC.

- Update HOST_OPENJDK_BIN_VERSION for OpenJDK 25.

- Update the expectedVersion variable in JniTest.java from 0x00150000
  (JNI 21) to 0x00180000 (JNI 24/25).

Tested with:
$ ./support/testing/run-tests -o ~/br-test-py/ -d ~/br-test-dl/ \
    tests.package.test_openjdk.TestOpenJdk

681b92664d support/testing: TestOpenJdk: remove stime() function call
stime() has been deprecated in glibc 2.31 [1] and replaced with
clock_settime(). Let's replace the stime() function call used in
BR2_PACKAGE_OPENJDK_JNI_TEST sources with clock_settime().

Apply the same change as busybox [2]. Make sure that timeToSet
has been zeroed.

With that fixed, the test "Call Native Library to Set System Time"
succeed:

  [BRTEST# java -cp /usr/bin JniTest
  Test: Get JNI Version passed
  Test: Read Native String Constant passed
  Test: Write Java String to Native Library passed
  Test: Write Java Char Array to Native Library passed
  Test: Write String Member to Native Library passed
  Test: Set String Member from Native Library passed
  Test: Execeute Java Function from Native Library passed
  Test: Instantiate Java Class passed
  Test: Call Native Library to Set System Time passed
  [BRTEST# echo $?
  0

The last external toolchain using a glibc 2.30 was the Bootlin
aarch64--glibc--bleeding-edge-2020.02-2, so since then TestOpenJdk
is broken.

095cab35a9 package/openjdk{-bin}: drop OpenJDK11 and add OpenJDK21
OpenJDK 21 is out and with it, OpenJDK11 is now EOL.
See: https://endoflife.date/oracle-jdk As such, drop support for 11 and do the
following:

  - The 0001-Add-ARCv2-ISA-processors-support-to-Zero.patch patch now applies to
    both 17 and 21. Move it out of the version-specific directoriy.

  - BR2_OPENJDK_VERSION_LTS is now set to 17.

  - BR2_OPENJDK_VERSION_LATEST is now set to 21.

  - Drop --disable-hotspot-gtest as it has been removed, and was ignored in 17.

  - Add two separate HOST_OPENJDK_BIN_VERSION defines in openjdk-bin.mk as
    there is not a point release yet for OpenJDK 21.

  - Update the expectedVersion variable in JniTest.java from 0x000A0000 to
    0x00150000

Tested with:
./support/testing/run-tests tests.package.test_openjdk.TestOpenJdk.test_run

e9a02417f3 package/openjdk-bin: install to host/usr/lib/jvm
Buildroot currently installs openjdk-bin to $(HOST_DIR)/ instead of the more
traditional (for java installations) $(HOST_DIR)/usr/lib/jvm.

As described in https://bugs.busybox.net/show_bug.cgi?id=13001

"Openjdk-bin provides it's own libfreetype.so and places it into
$(HOST_DIR)/lib/. This library causes build failures with the
host-xapp_mkfontscale package due to the overwritten libfreetype.so.

mkfontscale.o: In function `doDirectory':
mkfontscale.c:(.text+0x1a80): undefined reference to `FT_Get_BDF_Property'
collect2: error: ld returned 1 exit status

Reproducing the error is done by repeating the following steps.
make host-freetype
make host-openjdk-bin
make host-xapp_mkfontscale"

There are two options for fixing this problem:

 1) add host-freetype and host-lksctp-tools as dependencies to host-openjdk-bin
    and then remove the provided libfreetype.so and libsctp.so libraries
    in a post_extract_hook.

 2) change the installation directory from $(HOST_DIR)/ to
    $(HOST_DIR)/usr/lib/jvm just like the target OpenJDK package and
    copy the entire source directories contents to the above location.

The second option provides the following advantages:
  - the directory structure is consistent with how we handle the target OpenJDK.

  - the HOST_OPENJDK_BIN_INSTALL_CMDS step is simplified.

  - packages such as Maven require directories of which we are currently not
    copying. These missing directories cause programs such as Maven to crash
    when running with an error such as
    "Can't read cryptographic policy directory: unlimited."

  - does not miss any other libraries that solution 1 would not cope with
    (e.g. libzip.so from host-libzip, or libnet.so from not-yet existing
    host-libnet, or libsctp.so from not-yet existing host-lksctp-tools)

Because the second option is both simple, easier to implement, is low-impact,
and fixes the problems described above wholly, it is the best to implement.

To implement the above changes, we must also modify the following files in the
same patch to match the host's new directory paths:

 - openjdk.mk
 - openjdk-jni-test.mk
 - openjdk-hello-world.mk

To avoid having to change all those packages in the future, expose two
new variables, HOST_OPENJDK_BIN_ROOT_DIR which contains the path where
the openjdk-bin was installed in, and JAVAC, which contains the path to
the javac compiler (modeled after the way the autoconf et al. variables
are set and exposed).

Tested with:
./support/testing/run-tests -o out -d dl tests.package.test_openjdk.TestOpenJdk

6aee78c894 support/testing: openjdk JNI test cases
This test case builds a native library and ensures a Java class can load
and interact with the native library. The test also verifies Java code
can make system calls via the native library.

df7bf8fb41 support/testing/tests/package/test_openjdk: new test
This test is a simple "Hello, World" integration test of the OpenJDK
package.

It compiles the Java app on the host, then runs it on an emulated
AARCH64 target and verifies "Hello, World" is printed.
