Validate staticdata and object property length limits (#11511)
Some games provide users with enough freedom to create items
with metadata longer than 64KB, preventing this from causing
issues is on them but we'll still do the minimum not to abort
the server if this happens.

947466ab28 (se)SerializeString: Include max length in the name
This commit clarifies the maximal length of the serialized strings.
It will avoid accidental use of serializeString() when a larger string can be expected.

Removes unused Wide String serialization functions

5146086a64 Drop content_sao.{cpp,h}
Move LuaEntitySAO to a new dedicated file
Drop TestSAO (useless object)
Drop the old static startup initialized SAO factory, which was pretty useless.
This factory was using a std::map for 2 elements, now just use a simple condition owned by ServerEnvironment, which will be lightweight, that will also drop a one time useful test on each LuaEntitySAO creation. This should reduce server load on massive SAO creation

a067d40454 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.

2c860a6a42 ServerEnvironment & StaticObject cleanups
* isFreeServerActiveObjectId is now part of ServerEnvironment
* getFreeServerActiveObjectId is now part of ServerEnvironment
* StaticObject constructor now take ServerActiveObject instead of type + string. This permits to remove a big string copy in some code parts

0cde03254a Don't serialize StaticObjectList with > 65535 objects
Because the count is serialized as u16, this would cause overflow.

If minetest later deserialized a mapblock with an incorrect
static object count, it would be unable to find the NameIdMapping
(which comes after the StaticObjectList) and abort with an error
such as "Invalid block data in database: unsupported NameIdMapping
version" (issue #2610).

f7d65091f8 serialize.h: use machine native byte swapping if available, fall-back to previous generic method if not (supported for GCC using endian.h, detection done in cmake) write/readARGB8() - just write 32-bit color in one op, instead of 4 1-byte ops cleanup: removed unneeded buffer init for some serialize-out functions use a #define for the fixed point factor in read/writeF1000()
nodemetadata.cpp, nodetimer.cpp
	optimzation: simpler deserialize node position method

staticobject.cpp:
	cleanup: use util/serialize.h inlines instead of its own de/serialization

serialize.cpp:
	minor optimization/cleanup: avoid generation of unneeded string temporary

CMakeLists.txt, cmake_config.h.in: detection of endian.h

config.h: added HAVE_ENDIAN_H
