Version Control With Subversion Source

Finish issue #190 ("Incorrect statement in svnsync command-line
reference (?)").

* en/book/ref-svn.xml,
* en/book/ref-svnmucc.xml,
* en/book/ref-svnrdump.xml,
* en/book/ref-svnsync.xml
Universally tweak the example usage of the --config-option option in
the Reference matter to show how to disable HTTP compression,
something that applies to all of the relevant binaries (unlike the
use of autoprops or the use of the Serf HTTP library).

Finish #194 ("Fix about the use of external diff tools: 'svn diff
--force' allows it!").

* en/book/ch07-customizing-svn.xml
(svn.advanced.externaldifftools): Note that 'svn diff --force' will
perform a real diff even if MIME types indicate that it shouldn't.

Fix issue #233 ("Inconsistent example code for treeconflict").

* en/book/ch02-basic-usage.xml
(svn.tour.treeconflicts.example): Fix the "left side" label of a
couple of 'svn diff' output examples to read "revision 14" instead
of "working copy".

Finish issue #232 ("SSL is not only encryption").

* en/book/ch01-fundamental-concepts.xml
(svn.basic.in-action.wc.tbl-1): Claim that https provides "SSL
encapsulation (encryption and authentication)".

Finish issue #238 (1.8 change: New SVNMasterVersion Apache HTTP Server
configuration directive).

* en/book/ch06-server-configuration.xml
(svn.serverconfig.httpd.extra.writethruproxy.caveats,
svn.serverconfig.httpd.ref): Mention the SVNMasterVersion directive.

* tools/bin/spew-svn-command-options
Add 'svnauth' and 'svnmucc' to the list of programs whose options
are listed.

Bump copyright years.

For issue #234 (1.8 change: The Berkeley DB-based repository back-end
has been deprecated), move most of the Berkeley DB-specific
information to a new Appendix D and purge the book of the implication
that choosing a repository backend is really a thing.

* en/book/appd-berkeley-db.xml
New appendix, primarily populated with material culled from...

* en/book/ch05-repository-admin.xml
...this chapter, which now clearly favors FSFS.

* en/book/book.xml
Hook up the new appendix.

* en/book/ch03-advanced-topics.xml
* en/book/ref-svnadmin.xml
Update some cross references.
