Lubomir I. Ivanov 769aca9e95 equipment: sanitize 'tank_info' loop limits
In a number of places the global 'tank_info' array
is being iterated based on a 'tank_info[idx].name != NULL'
condition.

This is dangerous because if the user has added a lot of tanks,
such loops can reach 'tank_info[MAX_TANK_INFO]'. This is an
out of bounds read and if the 'name' pointer there happens to be
non-NULL, passing that address to a peace of code that tries
to read it (like strlen()) would either SIGSEGV or have undefined
behavior.

Clamp all loops that iterate 'tank_info' to MAX_TANK_INFO.
