Improve explanation of fifos.
Fifos are introduced as one of the seven file types but the explanation
given there does not include typical use cases. Add a paragraph about
fifos in the section on pipes and redirections to elaborate a little
how fifos facilitate inter process communication.

Improve table of contents menu and style sheet.
Major changes to the macros and the .css files which should improve
the look and feel of the pages a bit. Most notable is the increased
font size and the new layout of the table of contents dropdown menu.

FS: Remove Link to xfs.org page.
Code: 500 Can't connect to xfs.org:443 (Connection timed out)
Quoting XFS developer Darrick J. Wong on lkml:
> Is there a replacement URL for the xfs documentation?
None that I know of. Some of it went to xfs.org but then we lost
control of it. I tried to push other pieces went to xfs.wiki.kernel.org
but then we lost control of that too. Some of it is slowly migrating to
the kernel source code, but most of the old stuff is probably not
movable because people are afraid of mixing GPL and CC licensed data in
the same git repo/git server.

fs: Improve text on NFS silly renames.
Mention the rmdir problem and that as of nfs4.1 silly renames are
a thing of the past. Adjust the exercise which asks the reader to
create a silly-renamed file accordingly.

OSLV: Replace LXC section.
LXC got more and more complex, which made me write micoforia, a
minimalistic container framework for Linux. This commit replaces the
section on LXC by a similar section on micoforia.

Introduction: Fix duplication anchor.
Since the chapter list is contained twice on the intro page, we
must use different names for the anchors. To do so, change the
TABLE_OF_CONTENTS() macro to receive the name of the anchor as an
argument.

Fix two broken links.
The cluster and the user-info repo were merged recently, and
the cluster repo was removed afterwards. This commit makes
the links refer to the user-info repo instead.
This only affects the internal version of the pages.

Unix Concepts: Remove broken link.
The section on soft and hard links was made a subsection, which has
been merged into the section on Paths, Files and Directories. Remove
the misleading and broken link.

Improve menu.
The grey bar was not very intuitive to use, and it does not work with
all browsers. While elinks ignores the css and renders the menu at
the top of the page, at least one popular cell phone browser neither
shows the bar nor the menu, making it impossible to navigate the pages.
This commit reworks the css and html code to always show an hamburger
icon at the top left corner of the page. Moving the pointer on the
icon opens the menu.

Avoid stray '<!DOCTYPE>' text.
The markdown converter converts the doctype header into html which
results in a stray line at the top of the chapter. This only affects
the chapters that still use markdown: Bash, Git, Command Line
Utilities, and Gridengine.
This patch applies a silly workaround. In the long run, the chapters
should be converted to plain html.

Initial commit.
These files were created 2015 and orginally contained only the
material that was used for the Unix courses held back then at the
MPI for development biology in Tübingen.
Over time, more content was added and existing contents have been
improved. Development was tracked within the non-public "user-info"
git repository that also contains unrelated contents for internal
use within the institute.
In 2019-12 the title was changed to "Advanced Problems in the Linux
Environment" and the pages were made public. To give interested
readers access to the source code, contents were moved to a dedicated
repository that was made public in 2020-01.
No attempts were made to filter out the 269 commits of the user-info
repo that touched the files of the unix course.
