LU-5504 utils: add const qualifier to changelog accessors.

Commit 6e1365 changed 4 functions, and commit 0f22e4 accidentally
reverted them.

This patch put them back, as well as adding new ones to
changelog_rec_size(), changelog_rec_varsize(), changelog_rec_rename()
and changelog_rec_jobid().

6e1365 also changed changelog_rec_name() and changelog_rec_sname() to
return a const, but that is not possible anymore.
