change ktap_number to "long"

Since we are going to use 64 bit data in script,
repesent ip value or memory pointer, so "int" as
number is not enought for 64 bit data operation,
change ktap_number to "long" now.

There would not bring any performance issue.

There have one issue about read wrong 64 bit value
in compiler, use strtol to fix the issue.

All testcase are passed with this change.

The origin issue was reported by Qingping.

add testcase for 64-bit arith operation

Since we are already changed ktap_number to long,
so check the 64-bit arith operation correctness
in testcase.

Note, it's only work for 64-bit system, not 32-bit.
