Do not error out on validating a delta where a source file is missing in the target. This is valid. It can just have been removed.
Replace nimble_parsec with yecc and leex to avoid tearing hair out while debugging.
Fix handling of escaped double quotes in strings.
Add Confuse.Fwup functions for processing config that has already been read from file. This allows doing things more efficiently when making multiple calls and so on.
Fix issues where the Confuse.Fwup module was not interpreting meta.conf style definitions.
Add function for checking delta safety between two fwup configs.
Fix bug where Confuse.Fwup.get_features/1 could return a string in delta_fwup_version.
Add function to get fwup feature information and figure out minimum required version and version for delta updates.
Fix weird return format for Confuse.Fwup.get_delta_files/1.
Initial effort.
Supports the minimal parsing required to extract relevant information from meta.conf as used in the fwup tool. It will not interpolate variables or any other exciting bits. It will not perform includes.
