78ed8034d2 Add a const JNINativeMethod[] overload for registerNativeMethods()
The JNI interface expects a const JNINativeMethod[] and our wrapper
takes a non-const. Also, this was causing refactoring of exisisting code
with a const JNINativeMethod[] to fail because the call expects a
non-const.

34f72ca52e QJniEnvironment: extend API
This patch adds some convenience methods to QJniEnvironment API:
* an overload of registerNativeMethods() that accepts jclass instead
  of const char *className.
* a findMethod() function is added to query a methodID of a static
  or nonstatic method by its name and signature.

1359238572 Replace conversion operator by operator* in QJniEnvironment
Since conversion operators do implicit conversion that might bring
some potential issues while using the API, let's stick to having
an operator* instead.

deca7cd730 Fix registerNativeMethods for good
The initial implementation and the commit
c00ab6f8ea was wrong:
* env->findClass() in fact returns a global reference, and in any
case we shouldn't be calling that, instead QJniObject would be
enough.
* The size param provided to env->RegisterNatives was wrong.
* A test for registerNativeMethods() is added to ensure such break
is not repeated again.

4e60681c87 Make QJniObject and QJniEnvironment public API
As part of Qt 6 restructring for the extras modules, this change exposes
the Jni APIs which are very important for Android platform. This patch
adds the APIs QJniObject, QJniEnvironment, QJniExceptionCleaner based
from private QtCore and QtAndroidExtras.

The Jni interface is cross-platform which justifies the name, but
currently, this API is used mainly for Android, and the naming comes
generic without Android keyword to avoid any future limitation on
supporting other platforms.

[ChangeLog][QtCore] Add new QJniObject, QJniEnvironment and
QJniExceptionCleaner APIs.
