Closes#4708
This updates jsoncpp, mbedtls, TCLAP and SQLiteCpp to their latest stable release. A few additional changes were needed:
* jsoncpp deprecated Reader, FastWriter and StyledWriter which I've replaced
with some helper functions in JsonUtils.cpp
* SQLiteCpp changed how it builds with external sqlite libraries, now expecting
them to be installed. The simplest path was to remove sqlite from cuberite's
submodule and just use SQLiteCpp's internal version.
The algorithm was designed so All portals must be facing the center, no matter which block had the eye inserted in last.
Note: Still need to create a block entity so that portals don't become invisible when you relog.
Addresses part of #3445Fixes#3695
* Replaces AppendVPrintf with fmt::sprintf
* fmt::ArgList now used as a type safe alternative to varargs.
* Removed SIZE_T_FMT compatibility macros. fmt::sprintf is fully portable and supports %zu.
* Adds FLOG functions to log with fmt's native formatting style.
Adds a block handler for concrete powder and implements hardening to concrete.
Concrete powder turns into concrete when:
* It is next to water when it receives a block update
* It falls onto a water block (even with Physics SandInstantFall=1)
* Check for intersection between placed blocks and entities.
+ Implemented GetPlacementCollisionBox, to permit custom placement collision boxes for blocks.
* Factored block-entity placement checking into another function in cPlayer.
- Removed vector min/max functions
* Use GetWorld to get the world in DoesPlacingBlocksIntersectEntity.
+ Added block height checks, allow different cEntity subclasses to decide whether they will prevent block placement.
