Mapgen v6: Various mudflow code improvements and bugfixes (#8805)
Calculate 'i' inside 'y' loop to avoid 'i' and 'y' becoming
out of step due to the uses of 'continue'.
Simplify calculation of 'p2d' when coordinates are inverted.
Remove some unnecessary and unreliable 'index out of
voxelmanip' checks.
Move calculation of '&em' out of loops.
For 'Loop further down until not air' code, use y coordinate
to detect being out of voxelmanip, instead of checking index
which did not detect that.
Add and improve comments.
Indent the 'for (;; y--) {' loop.
Improve format and fix codestyle issues.

Inventory: Send dirty lists where appropriate (#8742)
This change reduces the amount of sent data towards clients. Inventory lists that are already known to the player are skipped, saving quite some data over time.

Add player sprite textures back into the engine as a fallback (#8823)
'player.png' and 'player_back.png' are hardcoded into the engine as
the default appearence of the player object, so the textures should
be present in the engine.
This results in a functional fallback sprite player for when a game
has no player appearence related code.

Mapgen v6: Fix mudflow iteration and iterate twice (#8795)
In MapgenV6::flowMud(), the previous implementation of coordinate
inversion caused the 2 inverted mudflow iterations (out of the 3
iterations) to not loop over the area, so only 1 non-inverted
iteration occurred.
Fix this bug but only iterate mudflow twice, as mapgen v6 has only
had 1 iteration for many years. There is now a good balance of 1
non-inverted iteration and 1 inverted iteration.

Fix unnecessary exception use in 3 more methods (#8791)
* Fix unnecessary exception use in Server::SendBlocks
The code in this method calls getBlockNoCreate and then
messes around with try...catch to skip blocks which are not
in the memory. Additionally, it repeatedly calls
m_env.getMap() inside this loop. Speed the code up by
extracting the m_env.getMap() out of the loop and getting
rid of the try...catch.
* Fix unnecessary exception use in Server::SendBlock
Another unnecessary try...catch is slowing down
Server::SendBlock. Remove that to speed it up and get a nice
side effect of simplifying the code in question.
* Fix unnecessary exception use in MMVManip::initialEmerge
Remove another unneeded exception usage from
MMVManip::initialEmerge to speed that code up and simplify
it but be careful to not remove the braces as there is a
TimeTaker in use there.

Clear old item groups when they are overridden. (#8753)
This fixes overridden items keeping their old groups in the group to
items mapping even after their groups have been changed in lua.
It also prevents a more widespread issue where overriding an item
will add its content ID *twice* to the mapping, resulting in odd
behaviour in features such as ABMs.

Handle multiple deserialization of a block's entities
This fix consists of two parts:
- Clear the list of stored entities. This has no side-effects.
- Catch the case where active entities exist and print a message.
Clearing the active entitiy list has side-effects that should
be handled. (those entities are known to the environment and
to clients).
As avoiding those side-effects is more complex, and as this
problem is not expected to occur (with PR #4847 merged), there
is no real incentive to implement this ATM.
This issue was a contributing factor to bug #4217. With the other
contributing factor removed (PR #4847), this commit makes sure this
factor does not go unnoticed if it ever happens again.

Fix breakage of non-GLES2 setups (#8774)
The commit 526a9e4b66abaf83eb6b1aaa3e93375acd87b830 breaks
the non-GLES2 setups because the code that is intended to
handle that is behind "elseif()" which is interpreted as
"elseif(false)" and thus the code never gets executed. Fix
that by changing the offending line to else().
Additionally, to avoid breaking the server only build
(which shall not have a dependency on GL/GLU/GLES at all),
enclose the entire block code in if(BUILD_CLIENT).

Avoid crash caused by, and improve, 'findSpawnPos()' (#8728)
Avoid an unsuitable spawn position (which if outside mapgen limits can
cause a crash) if the main 0-3999 loop reaches its end. Fallback to a
spawn at 0,0,0.
Check the mapgen-returned 'spawn_level' value for being outside limits.
When 'air_count' reaches 2, move back down 1 to spawn in the lower
empty node.
If the spawn position is disallowed by 'objectpos_over_limit()', 'break'
from loop instead of 'continue' because positions above are probably
also over limit.
Reset 'air_count' to 0 if an obstruction is found, to make 'air_count'
consecutive empty nodes.
Allow spawn in 'airlike' drawtype nodes such as mod-added vacuum,
alien atmospheres, fog etc.

Do not add group values of zero to group lists. (#8751)
This fixes an issue where when the engine looked up groups (for example,
in ABM node names), NodeDefManager's m_group_to_items would contain nodes

It brings consistency to the behaviour described in the api

ContentCAO: Fix broken attachments on join (#8701)
What happened:
1) Object data is received. Client begins to read the data
2) Client initializes all its children (gob_cmd_update_infant)
3) Children try to attach to parent (yet not added)
4) Parent initializes, is added to the environment
And somewhere in between, Irrlicht wrecks up the attachments due to the missing matrix node.
The solution here is to:
1) Use the same structure as ServerActiveObject
2) Attach all children after the parent is really initialized
