Kotlin module (3.x): some work needed wrt JSTEP-4 (unchecked exceptions)

[cowtowncoder]

So, as per email I sent on jackson-dev, there is work for JSTEP-4 (https://github.com/FasterXML/jackson-future-ideas/wiki/JSTEP-4), in particular:

FasterXML/jackson-databind#2177

and I intend to merge changes to master of most repos soon (January 19th, 2021), with force publish to get 3.0.0-SNAPSHOT. Right now changes are on exp/jstep-4-for-3.0 branches of affect repos, most notably for jackson-core and jackson-databind.

This issue is just created for coordination: I will update details once I merge changes. Not the ideal mechanism for sure, but hope it's better than mailing lists at least.

Changes mentioned have now been made and a new 3.0.0-SNAPSHOT of core components published.

In most cases changes needed should be simply either replacing "throws IOException" (and similar) with "throws JacksonException", or just removing (since exceptions are now unchecked): I have tried to indicate likeliest base exception for documentation purpose.

FWTW, does not look like this breaks anything in Kotlin module -- I assume Kotlin deals with all exceptions as unchecked.

Yep, I don't think this will require any changes in Kotlin.
