state: rework changeset calculation algorithm Calculate changesets directly by stabilizating the package graph instead of recalculating the whole graph and then diffing (similar approach as seen in 'smart' package manager). The algorithm is not complete: defferred search space forking is missing. So you don't always get a solution on complex graphs. Benefits: - usually the search state tree is smaller (less memory used) - speed relational to changeset size, not database size (usually faster) - touch only packages related to users request (can work on partitially broken state; upgrades only necessary packages, fixes #7) Also implemented: - command prompt to confirm operation if packages are deleted or downgraded - requesting deletion of package suggests removal of all packages depending on the package being removed (you'll get list of packages that also get removed if you want package X removed) - option --simulate to see what would have been done (mainly for testing) - an untested implementation of versioned dependencies and conflicts A lot has changed, so expect new bugs too.

pkg: dependencies to specific package checksum When package is installed from commandline, we should always install that specific instance of package (never favor repository version if it has difference identity). Otherwise we might not always end-up installing the .apk given on command line. The dependency is now against specific checksum identity (marked with >< dependency comparison). Fixes #492.

add: support for forced versions Support version numbers specified with packages. For example: apk add 'busybox<1.14' apk add 'squid=>3.0'

int apk_version_validate(apk_blob_t ver);
version: added apk_version_compare_blob() function We want be able to compare blobs so we basicly revert the old change, and make a wrapper that takes version strings.
