- Fix various call-sites that perform string<->FilePath conversions, to assume UTF8 encoded input,
  since Windows' native strings are UTF16.
- Fix the export header to export symbols under Cronet.
- Fix Cronet_Buffer_InitWithAlloc() to handle >32-bit sized allocations correctly under 32-bit.
- Fix the BufferTest.TestInitWithHugeAllocFails to request an allocation size that cannot be
  satisfied even under systems with over-commit.
