Use the current record offset in ssl3_get_record

The function ssl3_get_record() can obtain multiple records in one go
as long as we are set up for pipelining and all the records are app
data records. The logic in the while loop which reads in each record is
supposed to only continue looping if the last record we read was app data
and we have an app data record waiting in the buffer to be processed. It
was actually checking that the first record had app data and we have an
app data record waiting. This actually amounts to the same thing so wasn't
wrong - but it looks a bit odd because it uses the |rr| array without an
offset.

There is only one read buffer

Pipelining introduced the concept of multiple records being read in one
go. Therefore we work with an array of SSL3_RECORD objects. The pipelining
change erroneously made a change in ssl3_get_record() to apply the current
record offset to the SSL3_BUFFER we are using for reading. This is wrong -
there is only ever one read buffer. This reverts that change. In practice
this should make little difference because the code block in question is
only ever used when we are processing a single record.

This patch fixes an issue which causes the 'openssl ca' commands to
fail if '-config' is not specified even if it says so otherwise.
Problem is that the default config is not loaded and the conf variable
is NULL which causes an exception.
