FOV: Raise lower limit to avoid zoom-loading of distant world (#7234)
In the client, raise lower limit from 30 to 45 degrees, to avoid server
seeing this as a zoom and loading world beyond the server-set limit.
Add minimum in settingtypes.txt and enforce lower limit when set using
minetest.conf.

In the server, distrust the client-sent FOV if below the heuristic zoom
threshold and use the player object property 'zoom_fov' to check it, to
protect against hacked clients.

ae9b1aa177 Allow zoom to actually show more data.
This allows the client to retrieve blocks at a greater distance
from the server, thus allowing for a real zoom.

0732bf73a4 Reduce server FOV with forward speed
This causes blocks in front of the player to be rendered sooner and
blocks in the periphal view (that would soon be out of view) a bit later.
Overall this leads to smoother rendering as the player is moving around.

b97b9a550f Retrieve a small cone of blocks in the direction of the players velocity.
This helps retrieving the right set of blocks when the player is falling,
traveling on cart, or in general traveling in a direction different from
the view direction.

1d8d01074f ClientInterface: add a function to verify (correctly) if user limit was reached (#6258)
* ClientInterface: add a function to verify (correctly) if user limit was reached

CS_HelloSent is a better indicator of active slots than CS_Created, which are session objects created after init packet reception

Switch existing checks to ClientInterface::isUserLimitReached()

Use range-based for loop for getClientIds() used function too

This will fix #6254 (not the memory overhead if init is flooded)

d3131aeae7 Map generation limit: Rewrite
The previous implementation applied the setting to blockpos_over_limit(),
objectpos_over_limit() and in createSector(), causing many bugs near the
world edge.

First revert the previous implementation.
Rename blockpos_over_limit() to blockpos_over_max_limit() for clarity.
Add a new function to mapblock.h called blockpos_over_mapgen_limit() that
checks against the map_generation_limit setting, and call this only from
the code that decides where mapgen stops.
Use MAX_MAP_GENERATION_LIMIT in objectpos_over_limit() to reduce the
chance of bugs, there is no need to use map_generation_limit here.

b98f98b367 Fix incorrect distance computation for visible blocks (#4765)
The client would not compute the distance from the camera to
to a mapblock correctly. The result was that blocks that were in
view (i.e. not beyond the fog limit) would not be rendered.

With the improved distance computation, a range adjustment that
existed in clientiface.cpp is no longer required.

e17fbb31d6 Reset block send timer when invoking setBlock(s)NotSent()
As stated in this forum thread [1], I noticed that there is a
2 second interval in which inventory changes are shown on the
client. @yyt16384 found the source of these 2 seconds:
m_nothing_to_send_pause_timer is set to 2.0 every time there
are no changes to make, but this timer is not reset when
SetBlockNotSent or setBlocksNotSent are invoked. So in worst
case, the changed block will be sent over 2 seconds too late.

With this change, changed inventories are updated almost
immediately, but it causes additional connection load.
