lib: check frame_size is >= INT32_MAX

When parsing a frame header, validate that the frame_size is less than
or equal to INT32_MAX. Given frame_max is limited between 0 and
INT32_MAX in amqp_login and friends, this does not change the API.

This prevents a potential buffer overflow when a malicious client sends
a frame_size that is close to UINT32_MAX, in which causes an overflow
when computing state->target_size resulting in a small value there. A
buffer is then allocated with the small amount, then memcopy copies the
frame_size writing to memory beyond the end of the buffer.
