Richard Purdie 3a737a783c bitbake: data_smart: Make ExpansionErrors more readable ...

This adds context to ExpansionError messages which show the variable chain for which
expansion is being attempted. This should allow users to debug the issues more easily
than the current message (the first line alone below). Example output from a
SRC_URI which references ${S}:

bb.data_smart.ExpansionError: Failure expanding variable PV, expression was 0.1+git${SRCPV} which triggered exception RecursionError: maximum recursion depth exceeded while calling a Python object
The variable dependency chain for the failure is: PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV
-> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV
-> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV
-> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV
-> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV
-> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV

-> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV
-> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV
-> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV
-> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV
-> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV -> PV -> WORKDIR -> S -> SRC_URI -> SRCPV
-> PV -> BP -> FILESPATH

which is more useful that no output. We could truncate at repetition but I suspect
this makes this clearer as it stands so there is little value in complicating the code.
