When parsing ND-JSON streams, this is needed to indicate the
point when the ND-JSON stream is considered open, which
occurs just after the last HTTP_EVENT_ON_HEADER.
ND-JSON stream clients cannot rely on the first HTTP_EVENT_ON_DATA,
since that is only triggered by an event, which are optional and
may never be sent, or only sent well after the last HTTP_EVENT_ON_HEADER.
Closes#15952
In some applications, ESP_TLS_ERR_SSL_WANT_READ and
ESP_TLS_ERR_SSL_TIMEOUT are common results which
need handled at the next layer. Downgrade these
to debug.
Correct split header bytes
When the underlying transport returns header,
length, or mask bytes early, again call the
underlying transport.
This solves the WS parser getting offset when
the server sends a burst of frames where the
last WS header is split across packet boundaries,
so fewer than the needed bytes may be available.

1) pre-shift GCM last4 to use 32-bit shift
On 32-bit architectures like Aarch32, RV32, Xtensa,
shifting a 64-bit variable by 32-bits is free,
since it changes the register representing half of the 64-bit var.
Pre-shift the last4 array to take advantage of this.
2) unroll first GCM iteration
The first loop of gcm_mult() is different from
the others. By unrolling it separately from the
others, the other iterations may take advantage
of the zero-overhead loop construct, in addition
to saving a conditional branch in the loop.
