* NPC shop buy list received from the client is now validated for scripted shops (OnBuyItem), before the control is transfered to the script, as well (bugreport:3680, since r5841, related r8525). [Ai4rei]
* Resolved random compiler warnings. [Ai4rei]
- Silenced pointer size mismatch gcc warning for variables passed to script_setarray_pc (bugreport:4661, since r14613).
* Fixed sql mapreg loading code specifying output buffer size for SqlStmt_BindColumn without zero-terminator, leading to truncations of variable names and/or their values when using the maximum length (bugreport:1939, since r11245). [Ai4rei]
