c++ maintenance: eliminate old-style casts.

Old style casts have crept into the code base.

* buf.c (make_buf, buf_grow, buf_get_i8, buf_get_u8): Replace
old style cast with macro.

* ffi.c (align_sw_get, align_sw_put, ffi_be_i32_get,
ffi_be_u32_get, ffi_le_i32_put, ffi_le_i32_get,
ffi_le_u32_get, ffi_be_i64_put, ffi_be_i64_get,
ffi_be_u64_get, ffi_le_i64_put, ffi_le_i64_get,
ffi_le_u64_get, ffi_sbit_put, ffi_sbit_get,
ffi_init_extra_types): Likewise.

* hash.c (hash_buf): Likewise.

* itypes.c (c_i32, c_i64, c_u64): Likewise.

* stream.c (stdio_put_buf, stdio_fill_buf): Likewise.
