`OnEntitySpawned` is 1.11 only, so this is fine given our API stability guarantees.
Unfortunately the forward name clashes with quite a few plugins using the same name for their SDKHook callback. Normally we'd just put up with this but there are difficult to solve binary compatibility issues where those plugins will get the callback double-called, and there is a separate issue where the forward isn't called for all entity spawns (unlike the SDKHook), so most plugins can't switch to the forward anyway.
Resolves#1558.
This reverts commit 7bab9cc344.
The change in behaviour to the OnLevelInit forward params isn't obvious
when compiling a plugin, deprecate it to make it a lot more obvious that
something has changed.
Some plugins rely just on the timing of OnLevelInit rather than doing
anything with the entity lump, for these plugins offer a new OnMapInit
forward that is implemented in core rather than sdkhooks. If / when we
offer a new entity lump manipulation API in the future this'll be the
forward where it can be used to make changes.
Newer Source engine versions now use a dynamically allocated buffer for
the map entity lump, and some maps have over 16MB of entity data - far
larger than our 2MB limit.
There is no sane way we can currently handle this, so just remove the
functionality from the forward until a more comprehensive API can be
designed.
Fixes#1470
Looks like the |weapon| parameter went missing during the switch to the
transitional syntax.
There was no -Post typedef including the |damagecustom| bit at all too.
