 * Name: symtab_findbyname
 *
 * Description:
 *   Find the symbol in the symbol table with the matching name.
 *   This version assumes that table is not ordered with respect to symbol
 *   name and, hence, access time will be linear with respect to nsyms.
 *
 * Returned Value:
 *   A reference to the symbol table entry if an entry with the matching
 *   name is found; NULL is returned if the entry is not found.
 *
