> Log:
> Fix the "missing fsfs.conf" file situation in FSFS.
> This is a follow-up to the partial fix made in r905303.
>
> Make svnadmin upgrade create the fsfs.conf file, and make svnadmin
> hotcopy ask the user to run svnadmin upgrade if the file is missing.

> * subversion/libsvn_fs_fs/fs.h
> (SVN_FS_FS__MIN_CONFIG_FILE): New constant.
>
> * subversion/libsvn_fs_fs/fs_fs.c
> (upgrade_body): Try to create the fsfs.conf config file if it is not
> a file, and error out if it is a directory.
> (svn_fs_fs__hotcopy): Only try to copy fsfs.conf if the format is
> new enough to support fsfs.conf. If copying fsfs.conf fails because
> it does not exist, raise an error asking the user to run svnadmin
> upgrade.
