Version Control With Subversion Source

Remove possibly confusing language about licenses from the book:

* doc/book/book/ch01.xml: Daniel Rall pointed out that "Apache"
doesn't necessarily imply software to most people. Rather than
expand to clarify, it seems better to just not mention Apache/BSD.

* doc/book/book/ch01.xml: Cite book by title, as requested by cmpilato.

Rewrite the history section of the book, as threatened^H^H^H promised:

* doc/book/book/ch01.xml
(Subversion's History): Convert tone of mystical inevitability to
one of contingent activity.

* doc/book/TODO: updating some notes.

Next stop... is 1.0

The doors open on the left... at 1.0

There is no smoking, littering, or radio playing on the build train.

* doc/book/book/ch06.xml: Fix typo.

* book/ch06.xml: clarify misleading text around apache Location block.

* CHANGES:
Spelling fix.

* tools/test-scripts/svntest/README:
Update the minimum required size for the ramdisk to 570 Mbytes.

* doc/book/REVIEW,
* notes/releases.txt,
* notes/schema-tradeoffs.txt,
* packages/win32-innosetup/missing_shfolderdll.html,
* subversion/bindings/swig/perl/Client.pm,
* subversion/libsvn_fs/notes/fs-history,
* tools/cvs2svn/cvs2svn.1,
* tools/cvs2svn/cvs2svn.py,
* tools/cvs2svn/design-notes.txt:
Remove stutter.

* CHANGES: mention 'svn merge' change.
* doc/book/TODO: some extra ben-notes.

Revision 7740 changed the way the build finds stylesheets. Update
documentation and build to take this into account.

* doc/book/Makefile (XSL_DIR) : Remove this obsolete variable.
* doc/book/README : Don't say the build will looks for stylesheets
in a different directory than tools/xsl/ since this is not true.

* contrib/client-side/svn_load_dirs.pl.in:
Change the spaces between the deleted and added filename columns to
_'s to make the columns easier to visually line up.
Sort deleted and added filenames and directories by the lowercase
versions of their basenames instead of their complete path, which
makes finding files that were moved into different directories
easier to match up.
Patch contributed by Peter Gervai <grin@...>.
