Mega-commit with improvements and changes done in the past days.
- Introduce package states: unpacked, broken, installed, etc. Not yet finished, only unpacked and installed are used for now. - Move package metadata files in binary packages directly to the top directory, this speeds up some ops and makes easier to continue working in future changes. - xbps-bin: -C flag to check the hash of package files has been superseded by the 'check' target, which verifies the integrity of an installed package. - Use the 'essential' object when upgrading packages, overwritting current files. This is needed for critical packages like sh, libc and others. - Miscellaneous tweaks and improvements thorough the code. --HG-- extra : convert_revision : 2073fcc123efc24b3e9327b5e22aa91752f20df6
