Jian He reported the src/include/utility/tcop.h one and the remainder
were found by using a script to look for src/* and check that we have a

Make it clear that "astreamer" stands for "archive streamer".
Generalize comments that still believe this code can only be used
by pg_basebackup. Add some comments explaining the asymmetry
between the gzip, lz4, and zstd astreamers, in the hopes of making
life easier for anyone who hacks on this code in the future.
