While I added svn_fs_commit_txn2() function I think it should not be
exposed through svn_repos_* and RA layer.
FS layer currently doesn't treat svn:date as special property except
commit. And for commit operation it just an option add timestamp
within lock to guarantee them strictly ordered. As far I remember
Michael C. Pilato said somewhere that this intentional FS layer
Repos layer is different: it relies on svn:date order in functions
like svn_repos_dated_revision(). Repos layer has functions to load
repository dump, but this dump supposed to be created by
svn_repos_dump_fs() and have valid svn:date order. Adding option to
specify custom svn:date for new revision in svn_repos() layer will
break this invariant.
