Paul Bakker 1a1fbba1ae Sanity length checks in ssl_read_record() and ssl_fetch_input()
Both are already covered in other places, but not in a clear fashion. So
for instance Coverity thinks the value is still tainted.

In case full SSL frames arrived, they were rejected because an overly

Paul Bakker 956c9e063d Reduced the input / output overhead with 200+ bytes and covered corner
case

The actual input / output buffer overhead is only 301 instead of 512.
This requires a proper check on the padding_idx to prevent out of bounds
reads.

Previously a remote party could potentially trigger an access error and
thus stop the application when sending a malicious packet having
MAX_CONTENT_LEN of data, 32 bytes of MAC and a decrypted padlen of .
This would result in reading from in_ctr + 13 + 32 + MAX_CONTENT_LEN - 1 - 1
for 256 bytes (including fake padding check). Or 13 + 32 bytes over the
buffer length.

We now reset padding_idx to 0, if it's clear that it will never be a
valid padding (padlen > msg_len || msg_len + padlen + 256 > buffer_len)
