Listing 13.10 added in commit 42d9b5f32956
("together/applyrcu: Add example of retriggering a grace period")
is too tall for ebook-size builds.
As the \ebresizeverb command used to shrink code snippets requires
a verbatim element to be fed via \input{}, move the snippet into
CodeSamples/together/retrigger-gp.c.
The code snippet is now handled by fcvextract.pl.
