This test uses the SB API to set and read back bytes of data, and it works fine
when Python 2 is the scripting language. On Windows, however, Python 3 is the

Note this line from the test:

  addr_data = '\x11\x22\x33\x44\x55\x66\x77\x88'

The intent here is to create an array of eight bytes as a string literal. This
works in Python 2, but Python 3 treats those as a series Unicode code points,
and the CPython implementation happens to encode those code points as UTF-8.
The first seven characters encode directly as single bytes of the same value,
but the UTF-8 encoding of 0x88 is two bytes long: 0xC2 0x88.  Thus the input
array doesn't have the intended data at the end, and tests that rely on the
byte fails.

Adding the b prefix tells Python 3 that we want a byte array rather than a
string. With this change, the test now passes on Windows.

Fix TestMoveNearest on Windows

The header file for the DLL tried to declare inline functions and a local
function as dllexport which broke the compile and link.  Removing the bad
declarations solves the problem, and the test passes on Windows now.
