Fix code path that can overflow the native stack
de2b766 
We had a bug where a PHP program can infinitely recurse in a certain way
that doesn't hit any of our native stack overflow checks and causes the
process to segfault. Below I've included a snippet of the callstack that
caused HHVM to crash.

The fix is to make invokeFunc(), invokeFuncFew(), and invokeContFunc()
unconditionally perform a stack overflow check for the native stack. I
tried to keep the fix minimal and non-invasive so that we can get this
hotfixed if needed.

change logging in exit handlers to not avoid locking
e92f900 
Summary:
We have seen deadlock running `terminationHandler` -> `hasSubscribers` in 2 threads.
It's unclear which other thread is holding the lock.

To make things easier to debug next time, let's change terminationHandler (and
also main.cpp) to bypass the logging lock and write to stderr directly.

Zero size array causes crash in AsyncUDPSocket on llvm15
3302869 
Summary:
AsyncUDPSocket test cases are crashing when running under llvm15. During
debugging it seems that the issue is the fact that the code tries to allocated 0
size array. Changing the code to prevent such allocation.

This is not very clean why to fix, but I am not sure if there is better one.
Please let me know if you have any suggestions.

Sample crash:
```
$ buck test //folly/io/async/test:async_udp_socket_test
...
stdout:
Note: Google Test filter = AsyncUDPSocketTest.TestDetachAttach
[==========] Running 1 test from 1 test suite.
[----------] Global test environment set-up.
[----------] 1 test from AsyncUDPSocketTest
