rustdoc: bring it inline
doc: Update modules for containers
Update FFI signature table to use pipe format

Rustdoc doesn't seem like it's converting the old format to a table as we can see here:
http://static.rust-lang.org/doc/master/complement-cheatsheet.html#ffi-(foreign-function-interface)
This new format should fix that and it's also rendered by Github's markdown preview.
clarify docs for std:io::fs::Path::{is_dir,is_file,exists}; add lstat

Clarifies the interaction of `is_dir`, `is_file` and `exists` with
symbolic links.  Adds a convenience `lstat` function alongside of
`stat`.  Removes references to conditions.

Closes issue #12583.
