commandserver: drop tell() and seek() from channels (issue5049)

These operations are obviously invalid for file-like channels because they
will read or write protocol headers.

This patch works around the issue that "hg archive" generates a corrupted
zip file on Windows commandserver because of unusable tell() implementation.
But the problem still occurs without using a commandserver.

  $ hg archive -R not-small-repo -t zip - | cat > invalid.zip

So, this patch cannot fix the issue5049 completely.

#require symlink

  $ origdir=`pwd`

  $ hg init repo
  $ cd repo
  $ ln -s nothing dangling

avoid tar warnings about old timestamp

  $ hg ci -d '2000-01-01 00:00:00 +0000' -qAm 'add symlink'

  $ hg archive -t files ../archive
  $ hg archive -t tar -p tar ../archive.tar
  $ hg archive -t zip -p zip ../archive.zip
