8312065: Socket.connect does not timeout when profiling

[yanglong1010]

Hi,

This pull request contains the backport of JDK-8312065, commit 1ce12c4 from the openjdk/jdk17u-dev repository.

I added the test B8312065.java. The test will fail on the JDK8 without my fix, and it will pass on the JDK8 containing my fix.
This test relies on libNativeThread to get the OS thread ID of the Java threads, and send signals to OS threads.
The libNativeThread was introduced to test the fix for JDK-8237858. However, JDK-8237858 only exists in Java 10 and above. There is no JDK-8237858 problem on Java 8, so JDK-8237858 cannot be backported to Java 8.
In order to use libNativeThread, I copied it to my backport.

I ran all the jtreg tests in test/jdk/java/net/ServerSocket,test/jdk/java/net/Socket,test/jdk/java/net/SocketOption,test/jdk/java/net/ipv6 on my host, all passed.

Thanks!

@phohensee I didn't see your approval. Is it because this pull request has been closed by bot. I've reopened it, would you try again ?

/approval 8312065 request I would like to backport this fix to jdk8u-dev.
Low risk: Do not perform redundant loop retries for NET_Poll. Existing tests have proven that it does not affect the original functions, and a dedicated test for this issue has been added.
Testing: All GHA tests are passed. I ran all the jtreg tests (test/jdk/java/net/ServerSocket,test/jdk/java/net/Socket,test/jdk/java/net/SocketOption,test/jdk/java/net/ipv6) related to jdk.net.usePlainSocketImpl on my host, all passed.
Clean backport.
