Replace __tsan::OverrideFlags with __tsan_default_options()

[GoogleCodeExporter]

It's currently only possible to set the default TSan options in the client 
program by declaring the __tsan::OverrideFlags() function that modifies the 
flags.
This approach requires the client to be aware of the layout of the 
__tsan::Flags struct, which changes over time. For some clients it may be 
inconvenient, e.g. it's hard to support two different compiler versions with 
different flags.
We need to introduce the 'char *__tsan_default_options()' function similar to 
that used by ASan and MSan instead.
