Bump Gradle from 6.8.3 to 8.10.2 and increase the minimum required
Java version from 8 to 11 (SMACK-953).
The switch from Java 8 to 11 caused some Bytecode portability issues
regarding NIO Buffers. Java changed with version 9 the return type of
some subclasses of Buffer to return the specific Buffer type instead
of the Buffer superclass [JDK-4774077]. For example, ByteBuffer.filp()
previously returned Buffer, while it does return ByteBuffer now.
This sensible change was not reflected by the Android API [1], which
means that AnimalSniffer rightfully started to complain that there is
no method "ByteBuffer ByteBuffer.flip()" in Android, there is only
"Buffer ByteBuffer.flip()", and those are incompatible methods on
Java's Bytecode layer.
As workaround, this changes
return charBuffer.flip().toString();
to
((java.nio.Buffer) charBuffer).flip();
return charBuffer.toString();
to restore the Bytecode portability between Android and Java.
Errorprone also got new checks, of which JavaUtilDate and JdkObsolete
are wroth mentioning.
JavaUtilData basically strongly recommends to use Java's newer time
API over java.util.Date. But since Smack was Java 8 until now,
j.u.Date is widely used.
Similar JdkObsolete mentions obsolete JDK APIs, like data structures
like Vector and Stack. But mostly LinkedList, which should usually be
replaced by ArrayList. And this is what this commit largely does.

Due to a change in Smack 4.5.0-beta2, test execution of (all) SINT tests is aborted when `FormTest` is executed.
It appears that Smack now has more strict argument validation when setting thread IDs on message stanzas. This validation should not fail for the tests that are shipped with Smack.
This is the stack trace when executing the failing test (which no longer occurs after the change in this commit is applied):

After a room is destroyed, the MultiUserChat-stored representation of the 'join' state of any occupant should be updated to reflect that the user is no longer in the room.
This fixes a problem where an occupant (that not itself triggered the destruction) appears to continue be part of a room after its destruction.
Additional integration test assertions are added to check for the invalid state fixed by this commit.
fixes SMACK-949
Only list-multi and list-single fields require at least one value when
submitting a form. In other cases, for example XEP-0045's
muc#roomconfig_roomadmins, which is of type jid-multi, is used without
any values to reset the room's admins list.
Fixes SMACK-946.
