Subject: Support `use ...::self` imports
X-Git-Tag: v0.0.108.0^2~27
X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=e6b040d51589d726cb506830e2b0e0363f411634;p=ldk-c-bindings

Support `use ...::self` imports

Previously we'd supported `use self:...` but this adds support for
using some path that ends with `self`.
