Version Control With Subversion Source

Improvements to the book.

* doc/book/book/ch01.xml
Split the list of programs into client-side and server-side.

* doc/book/book/ch03.xml
Fix an example of "svn resolved" usage.

* doc/book/book/ch08.xml
Use simpler syntax for indicating repeatable arguments, to match the built-in
help (issue 1377, r6525).
Move "propset" and "revert" subcommands to restore alphabetical order.
Fix simple errors in a few synopsis lines.
Demote the warning that "svnadmin" refers to the repository by a path rather
than a URL to a normal paragraph, because no danger is involved and to bring
it in line with the corresponding note for "svnlook".

* doc/book/book/appc.xml
Fix mark-up of an email address ("<email>" instead of "<address>").

* book.xml: use the real title of the book.

Finish Issue #1074 (Need a svnadmin command to verify that the repository
is not corrupted). Patch (mostly) by John Szakmeister <john@...>.

* subversion/svnadmin/main.c
(cmd_table): Add new subcommand 'verify'.
(subcommand_dump): Minor no-op changes.
(subcommand_verify): New.

* subversion/libsvn_repos/dump.c
(dump_node, write_revision_record, svn_repos_dump_fs): Don't write
to NULL output streams.
(svn_repos_dump_fs): Don't write to a NULL output stream. Also,
when the output stream is NULL, print feedback messages that say
"Verified revision" instead of "Dumped revision".

* subversion/include/svn_repos.h
(svn_repos_dump_fs): Modified docstring to reflect the acceptance of
a NULL dumpstream.

* subversion/doc/book/book/ch05.xml
Document the new 'svnadmin verify' command.

Document the new "svnadmin list-dblogs" and "list-unused-dblogs" subcommands.

Next stop... is Beta.
The doors open on the right... at Beta.
There is no smoking, littering, or radio playing on the build train.

* TODO: More stuff todo.

* doc/book/book/ch01.xml
Some minor fixes. Patch somewhat by Matt Blais <mblais1@...>.

* doc/book/book/ch06.xml : Small grammar fix.

* notes/releases.txt: Add some truth.

* doc/book/README: Update some stale URLs, fix some paths.

Modifications to the book.

Patch contributed by Francois Beausoleil. This closes issue 1187.

* doc/book/book/appa.xml:
Updated the section about the status codes to show the most common ones.
Added reference to other sections for more details.
Left in a comment about the CVS update codes discussions that should
be moved elsewhere.

Sometimes, some of the PNGs in doc/book/book/images/ shows up as
black squares in stead of pictures.

* doc/book/book/images/ch04dia1.png: Adjusting the file to look as a
image again in svn-doc.chm (the Windows HTML-help file)
