Stack overflow in error report code

[dzid]

Running on a Win32 platform. If call to Win32 TlsAlloc() function made from CPLGetTLSList() fails, there is infinite recursion as CPLError() eventually enters the same code again and again until stack overflows.

Another part of the problem is that even if CPLError() worked, the returned (invalid) index is then used in TlsGetValue() function that may either crash or return 0, making CPLGetTLS() to crash.

I understand that it is very unlikely for TlsAlloc() to fail, however I discovered this scenario from a real client's crash dump so that's definitely possible.

I believe this is a duplicate of #4175 fixed in GDAL 1.10.0
