For every dev-install the install directory in rawbuild had to be removed. This
patch fixes that and consecutive dev-install works without manual intervention.

Replace system calls which performed single-file permission sets with calls to the built-in chmod.
Replace the implementation of create_directory with a call to create_directory_with_privileges.

Replace several system calls which performed single-file permission sets with the built-in chmod command.

Renamed all extensions to --enable-ext-* because
"we do want to present them together in ./configure --help"

See: b765a28ea9d63b60a14786b1a5484227175d413e

Deprecated old options not removed but commented instead.

¡There are still extensions which are only in build/configure.in!

Changed BUILD_TYPE from OOo to LibO

See: Elide all "SO:" and "OOo:" build.lst prefixes

Will be used by filter/source/config/fragments/makefile.mk.

Cwd::realpath does not work if the path does not exist

This fixes fdo#30568

it was logical problem when I updated the code for fdo#30837

- Pulled together all extension related options in one place in the
  configure, they were cluttered all around the place. We do want to
  present extensions together in ./configure --help.

- Add an -ext- to these configure options to clarify they are
  extensions:
  --enable-ext-presenter-ui, enable-ext-presenter-minimizer,
  --enable-ext-presenter-console, enable-ext-pdfimport,
  --enable-ext-wiki-publisher
  (Similar changes should still be done to the rest of the extensions)

- Quit with explicit error message when using conflicting --without-java
  and --enable-ext-wiki-publisher.

- Remove some minor things.

Partially revert 58f59291db32e07b06311337be1e9f7a930291b2 - the name
here needs to match all those */prj/build.lst prefixes (which still
have "OOo:" at several places)

It breaks KDE3 build on SUSE.

The variables $unsetenv, $setenv, $unset, $set $D, $answer were unused
in this script and have been removed.

Previously we would have been writing out LinuxX86-64Env.Set and
LinuxX86-64Env.Set.sh which made my autocompletion useless. Simplify the
set_soenv.in to actually only produce 1 version which makes us require
bash as interactive build shell.

--with-unzip-home has been deprecated since 2003.
