On the 1.6.x-svn_fs_commit_txn branch, merge in r1052068 from trunk.

Flush out svn_fs_commit_txn() and svn_repos_fs_commit_txn()'s
documentation.

* subversion/include/svn_fs.h
  (svn_fs_commit_txn):
    Note that an invalid revision number is guaranteed to be returned
    if the commit fails.

* subversion/include/svn_repos.h
  (svn_repos_fs_commit_txn):
    Document how a successful commit is determined.
    Document how a post commit FS processing error and a post-commit
     hook error are chained together.
