Robert Haas a05dc4d7fd Provide readfuncs support for custom scans.
Commit a0d9f6e434bb56f7e5441b7988f3982feead33b3 added this support for
all other plan node types; this fills in the gap.

Since TextOutCustomScan complicates this and is pretty well useless,
remove it.

KaiGai Kohei, with some modifications by me.
