A datum in a virtual table is an 64-byte string. The strings usually take the form "name value". A vtable_row_t is an array of these data, and represents a row in a virtual table. It is a structure "imposed" on an already-allocated block of data. This struct does NOT allocate or deallocate anything.
Each "attribute" or entry of the row is identified by an integer.

Initialize a row for n attributes. Must be at least 1. Assumes we have enough space for this to happen. User of this row must have allocated enough space. Let the maximum value size be m.
