+
+ Add scratch file handles.
+
+ Now a file handle can refer to a disk file, to an in-memory
+ structure, or to the "inline" file, instead of just to a disk
+ file. The introduction of new categories means that special cases
+ for the inline file in a few places could be eliminated, but it
+ also means that code that assumed that a handle refers to a file
+ has to check for that.
+
+ Also, now file handles can be freed, so code now must be sure not
+ to access a handle after closing it (with fh_close()).
+
+ * Makefile.am: Add any-reader.c, any-reader.h, any-writer.c,
+ any-writer.h, scratch-handle.c, scratch-handle.h,
