GS_FT_get()intools/filetransfer.cdereferences the pointer fromcalloc()and stores the result ofstrdup()without checking either for failure (issue #123). Ifcallocreturns NULL the followingp->pattern = ...writes through a NULL pointer.This returns -1 on allocation failure, matching the existing convention in the sibling
GS_FT_put(), and frees the partially-built request ifstrdupfails.Closes #123
