- Remove xbps_repo_get_plist() and try to internalize all members at
xbps_repo_open() time.
- Added xbps_repo_open_idxfiles() to also internalize the index-files
plist from repository, which is really huge and must only be internalized
when needed.
- Improve how signed and verified repositories are detected.
- Misc optimizations and small performance improvements.
Bump XBPS_API_VERSION.
These are the core interfaces in the new API:
rpool - Interface to interact with the repository pool.
rindex - Interface to interact with repository indexes.
pkgdb - Interface to interact with local packages.
transaction - Interface to interact with a transaction.
This also brings new repository index format, making the index file
per architecture and being incompatible with previous versions.
The transaction frequency flush option has been removed, and due to
the nature of package states it was causing more harm than good.
More changes coming soon, but the API shall remain stable from now on.
