exchange: don't send stream data when server.uncompressed is set
Previously, bundle2 stream support would send out data even though
the streaming clone feature was disabled. This commit changes
the part handler to respect the server config.

# Script to get stable diff output on any platform.

# Output of this script is almost equivalent to GNU diff with "-Nru".

# Use this script as "hg pdiff" via extdiff extension with preparation
# below in test scripts:

# $ cat >> $HGRCPATH <<EOF
# > [extdiff]
# > pdiff = sh "$RUNTESTDIR/pdiff"
# > EOF

# USAGE: filediff file1 file2 [header]

# implementation to return 1 at detecting changes.
#
# On bash and dash, assignment to variable inside while-block
# doesn't affect outside, because inside while-block is executed
# in sub-shell. BTW, it affects outside while-block on ksh (as sh
# on Solaris).
