[Lazarus] Documentation update (CHM building, lazutils)

[Marco van de Voort]

As part of the 2.6.0 documentation effort, I regenerated the docs for FPC,
and as usual I also try to build the LCL docs. I had to create some XMLs for
non existing LCL units.

I also commited a clenaed up version of the script I use to generate lcl.chm
as "docs/html/build_lcl_chm.sh".

I noticed that the LCL is now dependent on other package(s). At least a
package "lazutils". There seems to be some documentation in
docs/html/lazutils but they are only moved former LCL documentation.

What is the plan with this package? Is it a part of the LCL or really an
optional component? The LCL docs refers to lazutf8 81 times. If it is just a
matter of generating an extra CHM and set up the buildscripts for it, just
say so and I'll do it.

I also noticed some copies of the RTl docs in docs/xml/rtl but these don't
seem to be diffs/additions but full copies (and now it is hard to find out
what these actually change). Can these be removed?

Below is the condensed error list:
