The TLS record type is a single byte value so we can
use uint8_t for it. This allows passing its address
directly to SSL_trace() instead of converting it to
a single byte type first.

We had two different macros for calculating the potential growth due to
encryption. The macro we use for allocating the underlying buffer should be
the same one that we use for reserving bytes for encryption growth.
Also if we are adding the MAC independently of the cipher algorithm then
the encryption growth will not include that MAC so we should remove it
from the amount of bytes that we reserve for that growth. Otherwise we
might exceed our buffer size and the WPACKET_reserve operation will
fail.

During read pipelining we must ensure that the buffer is sufficiently large
to read enough data to fill our pipelines. We also remove some code that
moved data to the start of the packet if we can. This was unnecessary
because of later code which would end up moving it anyway. The earlier move
was also incorrect in the case that |clearold| was 0. This would cause the
read pipelining code to fail with sufficiently large records.

TLS pipelining provides the ability for libssl to read or write multiple
