Commit Message

fix a bug in variable length short calculation which can cause corrupt keyvi files (#32)

fixes a off by 1 miscalculation between the length calculated by getVarshortLength and encodeVarshort, while the 1st returned 2 for 0x7fff the 2nd correctly returned 1 as 0x7fff fits in 1 byte (0111 1111 1111 1111 ). The same bug existed for the next boundary 0x3fffffff.

As a result of this miscalculation it was possible - although rather unlikely - that a bit in a bitvector was set, marking a written cell while it did not got written as the required space was 1 instead of 2. The consequence of the unwritten cell is a default to '\0', this '\0' caused a mismatch starting with version 0.2 where '\0' became a valid transition. This broken transition caused a segfault due to a broken pointer.
