Add more documentation for FUSE_CAP_EXPORT_SUPPORT (#917)
Add more documentation for FUSE_CAP_EXPORT_SUPPORT
Also remove the flag from passthrough_ll.c and passthrough_hp.cc
as these implementations do _not_ handle that flag. They just
cast fuse_ino_t to an inode and cause a heap buffer overflow
for unknown objects (simplest reproducer are the examples
in "man 2 open_by_handle_at", but to unmount/mount the file
system after name_to_handle_at and before open_by_handle_at).
