The distinction between native inputs and "normal" inputs can already be
determined by looking at the 'native?' field of <gexp-input>. The extra
'natives' field of <gexp> added complexity for no good reason.

(gexp-inputs)[native-input?]: New procedure.
Use it.

Before that, 'guix environment guile' (for instance) would define environment
variables that would refer to the "include" output of Bash, the "debug" output
of libgc, etc., even though these are not listed as inputs in the recipe of
'guile'.
* guix/gexp.scm (lower-inputs): Export.
* guix/scripts/environment.scm (evaluate-input-search-paths): Remove
'derivations' parameter; add 'search-paths'. Expect 'inputs' to be
a list of tuples. Adjust callers.

expression like #~#+#~#$coreutils would include those of the inner
gexp.

'ungexp-native' or 'ungexp-native-splicing'.
[collect-native-escapes]: Ignore everything below 'ungexp' or
'ungexp-splicing'.
From now own, (guix packages) depends on (guix gexps); it was the other
way around now. This means that (guix packages) code can use gexps.
