feat: optimize archive reading

Instead of trying to load every database and look for files, this commit
introduces the optimization in which, the service loads packages first,
groups them by database and load files later.

In some cases it significantly descreases times for loading files

+Check outdated packages
+^^^^^^^^^^^^^^^^^^^^^^^
+
+There are few ways for packages to be marked as out-of-date and hence requiring rebuild. Those are following:
+
+#. User requested update of the package. It can be caused by calling ``package-add`` subcommand (or ``package-update`` with arguments).
+#. The most common way for packages to be marked as out-of-dated is that the version in AUR (or the official repositories) is newer than in the repository.
+#. In addition to the above, if package is named as VCS (e.g. has suffix ``-git``) and the last update was more than specified threshold ago, the service will also try to fetch sources and check if the revision is newer than the built one.
+#. In addition, there is ability to check if the dependencies of the package have been updated (e.g. if linked library has been renamed or the modules directory - e.g. in case of python and ruby packages - has been changed). And if so, the package will be marked as out-of-dated as well.

+Implicit dependencies resolution
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In addition to the depends/optional/make/check depends lists the server also handles implicit dependencies. After success build, the application traverse through the build tree and finds
+
+* Libraries to which the binaries (ELF-files) are linked. To do so, the ``NEEDED`` section of the ELF-files are read.
+* Directories which contains files of the package, but do not belong to this package. This case covers, for example, python and ruby submodules.
+
+Having the initial dependencies tree, the application is looking for packages which contains those (both files and directories) paths and creates the initial packages list. After that, the packages list is reduced in the following way:
+
+* From any leaf exclude the package itself and possible debug packages.
+* If the entry (i.e. file or directory) belongs to the package which is in base group, it will be removed.
+* If there is a package which depends on the another package which provide the same entry, the package will be removed.
+* After that, if there is a package which *optionally* depends on the another package in the remaining list, the package will be removed.
+* And finally, if there is any path, which is the child of the entry, and it contains the same package, the package from the smaller entry will be removed.
+
+All those implicit dependencies are stored in the database and extracted on each check. In case if any of the repository packages doesn't contain any entry anymore (e.g. so version has been changed or modules directory has been changed), the dependent package will be marked as out-of-dated.
