When doing a cross contract call you can supply an optional Weight limit for that call. If one doesn't specify the limit (setting it to 0) the sub call will have all the remaining gas available. If one does specify the limit we subtract that amount eagerly from the Weight meter and fail fast if not enough `Weight` is available. This is quite annoying because setting a fixed limit will set the `gas_required` in the gas estimation according to the specified limit. Even if in that dry-run the actual call didn't consume that whole amount. It effectively discards the more precise measurement it should have from the dry-run. This PR changes the behaviour so that the supplied limit is an actual limit: We do the cross contract call even if the limit is higher than the remaining `Weight`. We then fail and roll back in the cub call in case there is not enough weight. This makes the weight estimation in the dry-run no longer dependent on the weight limit supplied when doing a cross contract call. --------- Co-authored-by: PG Herveou <pgherveou@gmail.com>

- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
