Code in rgb32_data_has_alpha possibly generate this warning using
clang:
utils.c:35:16: error: cast from 'uint8_t *' (aka 'unsigned char *') to 'uint32_t *' (aka 'unsigned int *') increases required alignment from 1 to 4 [-Werror,-Wcast-align]
line = (uint32_t *)data;
^~~~~~~~~~~~~~~~
Although the images are expected to be all aligned in this respect
use byte access on the data instead. This, beside fixing the alignment
issue also avoid problem with big endian machines (images in SPICE are
expected to have the alpha channel as the forth byte).

Currently red_stream_async_read cannot handle read of 0 bytes.
This would cause a wrong assert in async_read_handler.
Fixing the assert would just make the code wrongly detect a
disconnection (usually a return of 0 from read is handled that
way but happens also if you try to read 0 bytes).
Current callers of these function does not pass 0 as size however
handling data protocols having data_length+data this can happen
and is handled manually in red_sasl_handle_auth_steplen.
Avoid needing manually to check for this condition.
