Tor Lillqvist 76fc34baeb Make bridgetest exercise parameter passing in the C++/UNO bridge harder
The C++/UNO bridge for macOS on arm64 currently uses the Linux code.
Apple's ABI uses slightly different parameter passing on the stack,
though. See
https://developer.apple.com/documentation/xcode/writing_arm64_code_for_apple_platforms?language=objc

That has not been taken into account yet in the bridge code. The
bridgetest, when run on macOS on arm64, didn't notice, sadly, but
succeeded. With this change it crashes, as one would expect it to do.

Add one more byte and short parameter to the setValues(), setValues2()
and getValues() calls in the XBridgeTestBase interface. The stack
allocation for those [in] parameters to setValues() differ between the
Linux and Apple ABIs. Add corresponding attributes to the interface,
and members to the SimpleTest struct.

The changes to the source files in the cli subdirectory (C++/CLI,
VB.NET, and C#) are done blindly as they aren't compiled even on
Windows currently. Most likely the changes to them are incomplete and
erroneous.

Testing tools

== How to check compatibility between compilers ==

Since the interfaces used in the cpp bridgetest are not changed often
one can just build the cppobj.uno.dll and the constructors.uno.dll
(testtools/source/bridgetest) in an
old environment and then use them in the new environment. That is the files
are copied into the testtools/wntmsciXX.pro folder which corresponds to the
new environment.

On Windows this test will typically fail because the tests use the
cppu::getCaughtException function, which only works when all libs are build
using the same runtime.

This part of the test can switched off. To do this go into the
testtools/source/bridgetest folder and call
dmake compcheck=1

This will add a new compiler define (-DCOMPCHECK) and will be used in the
bridgetest.cxx to switch off the code which uses the getCaughtException function.
However, there is still a test which causes the test component to throw
and IllegalArgumentException. This still works.


== Using source/bridgetest for stress testing ==

Start a modified bridgetest_server (with the final "--singleaccept" argument
removed from the uno executable call) or a modified bridgetest_javaserver (with
the final "singleaccept" argument replaced with "multi" in the java executable
call), then start a modified bridgetest_client (with a final "stress" argument
added to the uno executable call).  The client will continuously establish
connections to the server which are immediately destroyed again.  The test will
run forever, unless an error occurs.
