Correct usage of sizeof() for pointer types
Given some pointer *x, calling sizeof(x) will give us the size of the pointer (4/8 bytes) not the size fo the underlying dereferenced structure. Use coccinelle to search for these occurrences in the source code, and correct them one by one. In the case of erl_node_tables.c, the erts_snprintf() calls used a much too small buffer. - run_erl.c: Use the size of the signal type, not its pointer. - erl_node_tables.c: Use the size of the _BUFFER in erts_snprintf() to make sure we can use the full space.
