Subject: build: Handle introspection a bit better
X-Git-Tag: archive/raspbian/4.12.3+ds-1+rpi1~1^2^2^2~22^2~5^2~43^2

build: Handle introspection a bit better

Error out if introspection is requested,
but g-ir-scanner isn't found.

And if introspection isn't explicitly disabled
but is required for building the docs, build it.
