(NB. I started sending this first with an incorrect patch attached, so
if there's another copy of this mail without this little "NB" notice,
ignore that one.)

Hi Mike, it sure has been a while! (So much for hearing from me
"tomorrow" ...)

Here's the second version of the patch. I have not implemented anything
in the RA/FS loaders for checking the versions of plugins; I began to,
but it got out of hand and I thought the main version checks should be
finished first. However I have added svn_libname__version() functions
for the plugin libraries. I guess these should eventually be added to
the vtables or something, and checked from the loaders...?

Proposed log message follows.

-- Edmund.

Implement library version functions, and check library versions in
command-line clients. Each library features a "svn_libname_version"
function that returns information on the Subversion version the library
is compiled as. Clients call their own "check_lib_versions" (or a
similarly named) function that uses svn_ver_check_list (from
libsvn_subr/version.c) to call the version functions of a list of
libraries, which ensures there are no version mismatches.

This change is a generalisation of r9697 to other libraries and
clients, and fixes issue 1861.

* subversion/libsvn_delta/version.c (svn_delta_version),
   subversion/libsvn_ra_svn/client.c (svn_ra_svn_version):
     New files, with functions for returning library versions.

* subversion/libsvn_delta/version.c (svn_delta_version),
   subversion/libsvn_diff/util.c (svn_diff_version),
   subversion/libsvn_fs/fs-loader.c (svn_fs_version),
   subversion/libsvn_fs_base/fs.c (svn_fs_base__version),
   subversion/libsvn_fs_fs/fs.c: (svn_fs_fs__version),
   subversion/libsvn_ra/ra_loader.c (svn_ra_version),
   subversion/libsvn_ra_dav/util.c (svn_ra_dav__version),
   subversion/libsvn_ra_local/ra_plugin.c (svn_ra_local__version),
   subversion/libsvn_repos/repos.c (svn_repos_version),
   subversion/libsvn_wc/util.c (svn_wc_version):
     New functions for returning library versions.

* subversion/include/svn_delta.h (svn_delta_version),
   subversion/include/svn_diff.h (svn_diff_version),
   subversion/include/svn_fs.h (svn_fs_version),
   subversion/libsvn_fs_base/fs.h (svn_fs_base__version),
   subversion/libsvn_fs_fs/fs.h (svn_fs_fs__version),
   subversion/include/svn_ra.h (svn_ra_version),
   subversion/libsvn_ra_dav/ra_dav.h (svn_ra_dav__version),
   subversion/libsvn_ra_local/ra_local.h (svn_ra_local__version),
   subversion/include/svn_ra_svn.h (svn_ra_svn_version),
   subversion/include/svn_repos.h (svn_repos_version),
   subversion/include/svn_wc.h (svn_wc_version):
     New function symbols.

* subversion/svnadmin/main.c,
   subversion/svnlook/main.c,
   subversion/svndumpfilter/main.c,
   subversion/svnserve/main.c,
   subversion/svnversion/main.c,
   contrib/client-side/svn-push/svn-push.c:
     (check_lib_versions): New function that checks the compiled
         versions of all svn libraries needed by this client.
     (main): Call check_lib_versions() and exit with failure if library
         versions are not adequate.

* subversion/clients/cmdline/main.c:
     (check_lib_versions): Add remaining library version checks.
