Silenced gcc warnings.

- Added parentheses to inline assignments.

- Removed the unused function "Twople".

- Unnecessarily initialized "iv" of BTree_ini().  (Compiler isn't smart
  enough to see that "iv" is never used uninitialized.)

- Added curly braces.

- Removed unused var "v" from BTree_setstate.

- Used "void" in place of empty parameter lists.
