e2d54c9f "shutdown when requested from lua in singleplayer too"

broke minetest's feature to connect to servers. The client crashed
after the connection init was complete.

Thanks to @sofar for reporting the bug.

Fixes #3498.

If an `XDG_CACHE_HOME` can't be found or `RUN_IN_PLACE` is enabled,
`path_cache` is left at its default of `$PATH_USER/cache`
(at a time when `PATH_USER` is `..`), rather than being reset to
`$PATH_USER/cache` after `PATH_USER` has been properly set.

And replace manual tests for error with SQLOK() where possible.

This allows other applications (e.g. minetestmapper) to interrogate
the database while minetest is running, without causing an almost
certain minetest crash.

This reverts commit f14e7bac.

Reverted due to missinterpretation of agreement, obvious dislike and me not interested in doing fights for feature I don't actually need

Before, minetest.request_shutdown didn't shut down
singleplayer instances or server instances from the server tab.

This commit fixes this. Fixes #3489.

-> Redis backend: break from switch to fix bug
-> Dummy and redis backends: reserve the count so that creating the list is faster

The freehoster these files were hosted on is shutting down soon-ish, they're now hosted on my VPS.

Before, sub-makes called by make were called without make knowing they
were sub-makes. This however led make's jobserver not do its tasks,
and the build process ended up with inefficient parralelisation. This
commit fixes this by applying the two ways the make manual tells
about: putting + to the start of the line (used when ndk-build is
invoked), and exchanging "make" with "$(MAKE)".

Before, make complained with messages like:

make[2]: warning: jobserver unavailable: using -j1.  Add `+' to parent make rule.

This complaint can now only been seen for openssl. openssl has issues
if make gets exchanged with $(MAKE): if exchanged, above error message
is multiplied for various subdirs of the openssl source tree.

On a 4 core box, "make -j 4" build time from "make clean_all" cleaned
source tree could be improved from 15:34 minutes to 10:45 minutes.
This means a speedup of 45%.

dcb91cf0 hacked around the biggest issue
this caused, but wasted a lot of CPU time and disk space  It also still
included a lot of other unwanted files.  This removes all of `doc/` except
the license, and also removes the server list.

Previous commit

70ea5d55 "Add support for limiting rotation of automatic face movement dir entitys"

by sapier has broken minetest's feature to open worlds. This was due to a
missing stack pop operation.

Thanks to @oleastre for reporting this bug and suggesting the fix.
