[PATCH] libsvn_fs_util: Move functions from fs.c to fs-util.c

Hello,

Please find attached a follow-up patch for r24350. It is based on the
discussion we had in this mailing list thread [1].

http://subversion.tigris.org/servlets/BrowseList?list=dev&by=thread&from=571463

In this patch, I've moved rest of possible functions from
libsvn_fs_fs/fs.c and libsvn_fs_base/fs.c to libsvn_fs_util/fs-util.c
library. FWIW, i ran 'make davautocheck' with this patch and do not see
any issues.

[[
Move all possible re-usable functions from libsvn_fs_fs/fs.c and
libsvn_fs_base/fs.c to libsvn_fs_util/fs-util.c library.

The list of affected functions are as follows:

base_version() and fs_version() --> svn_fs__version()
check_already_open() and check_already_open() --> check_already_open()

The above functions were static earlier, now they become non-static,
since they are moved to different library.

* subversion/libsvn_fs_base/fs.c
  Do not include "svn_version.h", but include the new candidate
  "private/svn_fs_util.h" header file.
  (check_already_open): Remove.
  (base_version): Remove.
  Rename base_version function name as svn_fs__version function name in
  library_vtable, FS library vtable list which is used by FS loader
  library.
  (svn_fs_base__init): Rename base_version() function as
  svn_fs__version() function.

* subversion/libsvn_fs_fs/fs.c
  Do not include "svn_version.h", but include the new candidate
  "private/svn_fs_util.h" header file.
  (check_already_open): Remove.
  (fs_version): Remove.
  Rename fs_version function name as svn_fs__version function name in
  library_vtable, FS library vtable list which is used by FS loader
  library.
  (svn_fs_fs__init): Rename fs_version() function as svn_fs__version()
  function.

* subversion/include/private/svn_fs_util.h
  Declare check_already_open() function to check if the filesystem is
  already open.
  Declare svn_fs__version() function to return the library version
  number.

* subversion/libsvn_fs_util/fs-util.c
  Include new dependent header files viz. "svn_fs.h", "svn_version.h",
  "svn_private_config.h" and "../libsvn_fs/fs-loader.h".
  check_already_open(): New function to check if the filesystem is
  already open.
  svn_fs__version(): New function to return the library version number.
