In the unlikely event that the return value from the read callback is
larger than the number of bytes we asked for, we can end up incrementing
buf->len beyond capacity. Check the return value from the read callback to
prevent this.

Provide an extensible buffer implementation that uses a read callback.2019-01-17T06:32:12+00:00jsing2019-01-17T06:32:12+00:00urn:sha1:dfcb2879ed4cb98147d3c6bcf56f7e6da34adacb
The read callback returns a TLS13_IO_* value on EOF, failure, want pollin
or want pollout, or a positive value indicating the number of bytes read.
This will be used by upcoming TLSv1.3 handshake message and record
processing code, both of which need the ability to read a fixed size
header, before extending the buffer to the number of bytes specified in the
header.
