I broke this in 46fd114e.

Correct parameter names mg_valleys to mgvalleys
Remove biome NoiseParams from MapgenValleysParams
Improve format of parameter code

This often broke the threading tests on OSX.

The old Ant build system has been deprecated for a while and new development is focused on Gradle.
I also removed a hardcoded string that lint caught and moved the patch files to a subdirectory.
I left the JNI files in the root directory.

Also, change the escape character to the more standard \x1b
Thus, it can be used in the future for translation or colored text,
for example.

Fix bug that was leading to oversized tooltips containing multiline text when it have multiple lines

Also, fix a nil error that can happen sometimes in
menu_handle_key_up_down

They break bzr-git, and bzr-git breaks the Minetest PPAs.

Previously, race conditions occurred inside logging, that caused
segfaults because a thread was trying to use an old pointer that
was freed when the string was reallocated. Using a fixed-length buffer
avoids this, at the cost of cutting too long messages over seveal lines.

The shadow bug at y = 63 was caused by dark air being placed as dust,
when the biome dust was unspecified it was falling back to 'air'
In dustTopNodes only dust == 'ignore' will disable dust placement

This fixes the problem that the first timer tick is an
overrun and causes all timers to expire immediately.

replaces #4003

Previous mountain terrain generation was by necessity placing
stone in air, this was removing air from any overgenerated
structures such as tunnels, dungeons and large caves
Moving it into the base terrain generation loop ensures that
only 'ignore' is replaced

generateRidgeTerrain: only return if node_max.Y < water_level - 16
Previously, if water level was set a few nodes above a mapchunk
border the river channel was only partially excavated

This seems very little cost and matches the old behavior more
closely. This will cause some more falling nodes to get added
to falling clusters. With the efficiency of the algorithm, this
really doesn't do much damage.

@SmallJoker has noted a bug that servers from the (local) main menu
favorites list can't be opened.

This commit fixes the bug by disabling any main menu based protocol
checks for servers from the favorite list.

Also, it fixes a second bug that happens when a server from the
public serverlist doesn't send its supported protocol versions,
most likely because its running a minetest older than commit [1].
Then we have shown an error msg that the server has enforced
one specific protocol version. This was most likely not the case.

Of course, we can't do anything better than do an assumption on
the protocol versions if they are not known. That assumption
should however be closest to the most often occuring case as
possible.

Also, some little cleanups.

Apply de morgan to simplify the logic.

Setting only loaded once, default value is to enable them.

Place biome top node on tunnel entrance floor
Instead of doing nothing at node_max.Y + 1 use 1-down
overgeneration for tunnel generation and noisemaps

Fix use of 'air_above' bool so that biome
nodes are only placed in tunnel floors
Minor code improvements
'Continue' when massive cave air is placed
