Hmm, in terms of maintainability, borrowing an implementation from glibc
doesn't cost much, since the code in glibc doesn't change often. Either way,
we'd have 2 implementations:
   canonicalize == canonicalize-lgpl != glibc canonicalize
or
   canonicalize != canonicalize-lgpl == glibc canonicalize

We cannot easily merge this into a single implementation, because with the
added canonicalize_mode_t argument and the use of file_name_concat, the
gnulib canonicalize differs significantly from the one in glibc.
