These are relatively complete, although only lightly tested.  Missing:

 - events
 - last_errno
 - user_cancel

Don't assume that if guestfs_case_sensitive_path returns NULL, that it
means the file does not exist.

The (previously undefined) behaviour of case_sensitive_path was that a
NULL return meant "either the file doesn't exist or some other error".
However in commit 973581780d8a006f336684fef6762801402d775d this was
changed so that if the last element of the path didn't exist, it was
assumed to be a new file and the (non-NULL) path of the new file is
returned.

This change breaks code (including in libguestfs) which tries to use
case_sensitive_path as a dual-purpose call to fix-up a path for
Windows and test if the file exists.  Such code should be rewritten so
that it explicitly tests for file existence after calling
case_sensitive_path.

I examined all the calls to case_sensitive_path in libguestfs and
modified them where necessary.

This adds standard LICENSE and BUGS sections to all of the man pages
that are processed by podwrapper.

Modify all the calls to $(PODWRAPPER) to add the right --license
parameter according to the content.  Note that this relaxes the
license on some code example pages, making them effectively BSD-style
licensed.

section.

Ensure each man page contains consistent COPYRIGHT and AUTHOR
sections.

Remove the LICENSE section.  We will add that back in podwrapper in a
later commit.

Since our minimum supported version is now 1.16 and mount was fixed in
1.13.16, it is now safe to replace mount-options + empty options with
mount wherever it occurs.

In libguestfs 1.20, you will be able to use 'add_drive'
instead of 'add_drive_opts' (except in the C bindings).

However until libguestfs 1.20 is the minimum stable version
people will still be using old versions where you have to use
'add_drive_opts'.  This makes the examples confusing.

Therefore continue to use 'add_drive_opts' in the examples
for now.
