* Revert "Revert bad duct-tape fix that broke lots of other things"
This reverts commit 4a4900e5e7ea1fd7b897b025b4b666fd2050f80a.
Player: Perform respawn actions when joining while dead
This fixes exploits related to #1567 by calling respawn logic on join when the player has zero health.
This is a shitty fix and doesn't solve the actual issues described in #1567, but it's a simple solution for the exploits related to it.
This also removes a cyclic dependency between TextFormat and Terminal, meaning that TextFormat is now standalone without any external dependencies.
This is also an API break. Beware all ye who wander here, master = bleeding-edge!
TAG_String has a UTF-8 payload, which makes it more expensive to work with. Also, skins can contain bytes which are not valid UTF-8 characters and will therefore be treated as corrupted by external tools.
Additionally a TAG_String can only hold 32767 bytes, which might become a problem in the future.
A TAG_ByteArray can hold up to 2GB of data, and there is no character encoding restrictions on it.
This fix doesn't fix existing data, but it will prevent the bug happening in the future by capping the length of strings to 32767 bytes, and throwing an exception if too long.
This extension hasn't been maintained in 4 years and it doesn't make sense to update it to PHP 7, since :shoghi: just dumped a blob of PHP into zephir. It's not worth the hassle of updating.
I prefer to modularise and then C-ify modules, so that they can be reused on their own.
SIGKILL constant is defined by pcntl, not by posix. If pcntl is not compiled then bugs can occur when trying to kill() the server (such as during a crash).
Closing the command window immediately when an error occurs is particularly unhelpful. This keeps the command window open so that the user can see what went wrong.

Exceptions occurring early in the start sequence (before BaseLang is initialized) will result in the server hanging and not killing process as expected. This works around that issue.
This was causing new players to inexplicably spawn in the wrong place when joining a world for the first time which had a different level name than folder name. With LevelDB worlds, this caused them to spawn wayyyy up at y=32767 for no good reason.
