  Log Message:
  -----------
  XrdTpc: Factor out recursive writes.

This separates the writing methods of the stream to avoid potential
recursion when dumping buffered data.  This also allows the buffer
to accept partial data so the beginning offset of the buffer is
always a multiple of the buffer size (i.e., the buffer offsets
always stay MB-aligned).

With this, a single incoming buffer from curl may be split across
two entries in order to keep alignment.

  Changed paths:
    M src/XrdTpc/XrdTpcStream.hh

  Log Message:
  -----------
  XrdTpc: Do not allow partial buffer writes

The multistream code uses an occupied buffer as an indication that
a request is ongoing; for now, we can't do partial buffer writes
as this causes the back-off code to think the buffer is free and
start too many requests.

  Log Message:
  -----------
  XrdTpc: Adjust buffer size based on number of streams.

As we only write when buffers are full and we don't need a full 16MB
buffer when we are doing single-streams (for single stream, we're only
waiting to accumulate a "large-enough" MB-aligned buffer), we can
simply decrease the buffer size.  Saves some allocated-but-unused
space.

  Changed paths:
    M src/XrdTpc/XrdTpcStream.cc

  Log Message:
  -----------
  XrdTpc: Always populate error buffer with messages.

Even when there's an internal logic error, make sure the Write
method populates the error message - if nothing else, will be useful
for debugging.
