Previously, we assumed that reply->str was NULL
terminated. However, this turned out to be not true,
as users reported crashes in strlen connected to
where reply->str was appended to an std::string.

Use the method recomended by the docs, to read the
length separately.

Add new node property 'floodable', default false
Define "air" as floodable = true in C++ and lua

Fix for commit 87dcee6a It uses the wrong variable and only covers some use cases. This change covers all use cases.

Removing the target file on other platforms was enabled likely unintentionally
by commit 5f1f1151.

This may be the reason why there has been corruption of files on Linux on hard
shutdowns.

Previously I described the problem and this fix in issue #3084.

My commit

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

This reverts commit 91bafcee.

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

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.

* Horizontal and vertical are used wrongly. Use height and width because
	horizontal/vertical describes different things. Thanks @kilbith for pointing out.
* Update minetest.conf.example and settings_translation_file.cpp
* Correct maximum/minimum copy paste mistake.

On non-windows platforms this just used a semaphore,
which meant that multiple calls to signal() would
result in wait() returning multiple times.

This is set to the XDG cache path where possible.
It's set to the app's cache path on Android.

Fix the type of the threshold value for mapgen.
The commit

a78dd7f2 "Fix spelling of noise_threshold"

has changed it to be read as int, but it can have non-integral values too.

Thanks to @kwolekr for pointing this out.

To terminate unwanted shadows from floatlands or realms above
Also add to LuaVoxelManip calc_lighting for use in mapgen mods
Remove the 2 argument calcLighting, mapgens now use the 5
argument form to specify the volumes for propagateSunlight and
spreadLight
In mgsinglenode replace calcLighting with setLighting and
clean-up use of tabs and spaces

On openSUSE luajit is not detected correctly.
This is because openSUSE is using a lua version suffix, like other Linux distributions do it also.
So the include directory is:
include/luajit-5_1-2.0

openSUSE sets that option to ON.

Fixes #3420.
