Add svn_ra_initialize function.  Currently, it does nothing; the reason for it
is so we can require it when used with the new svn_ra APIs in 1.2.

* subversion/libsvn_ra/wrapper_template.h (COMPAT_INITFUNC): Add pool
  to INITFUNC call.

* subversion/libsvn_ra/ra_loader.c (svn_ra_initialize): New function.
  (svn_ra_open, svn_ra_print_modules): Add pool to init_func call.

* subversion/libsvn_ra/ra_loader.h
  (svn_ra__init_func_t, svn_ra__local_init, svn_ra__svn_init,
  svn_ra__dav_init): Add pool argument.

* subversion/include/svn_ra.h (svn_ra_initialize): Declare.

* subversion/libsvn_ra_local/ra_plugin.c (svn_ra_local__init),
* subversion/libsvn_ra_svn/client.c (svn_ra_svn__init),
* subversion/libsvn_ra_dav/session.c (svn_ra_dav__init): Add pool argument.

* subversion/svnversion/main.c (main): 
* subversion/clients/cmdline/main.c (main): Call svn_ra_initialize.
