86a3f2d492 Add FORCE_NOT_NULL support to the file_fdw foreign data wrapper.
This is implemented as a per-column boolean option, rather than trying
to match COPY's convention of a single option listing the column names.

6e6cc5910b Make the file_fdw validator check that a filename option has been provided.
This was already a runtime failure condition, but it's better to check
at validation time if possible.  Lightly modified version of a patch
by Shigeru Hanada.

7c5d0ae707 Add contrib/file_fdw foreign-data wrapper for reading files via COPY.
This is both very useful in its own right, and an important test case
for the core FDW support.

This commit includes a small refactoring of copy.c to expose its option
checking code as a separately callable function.  The original patch
submission duplicated hundreds of lines of that code, which seemed pretty
unmaintainable.
