pg_basebackup: Refactor code for reading COPY and tar data.
Add a new function ReceiveCopyData that does just that, taking a
callback as an argument to specify what should be done with each chunk
as it is received. This allows a single copy of the logic to be shared
between ReceiveTarFile and ReceiveAndUnpackTarFile, and eliminates
a few #ifdef conditions based on HAVE_LIBZ.
While this is slightly more code, it's arguably clearer, and
there is a pending patch that introduces additional calls to
ReceiveCopyData.
This commit is not intended to result in any functional change.
