[swdb]: integration squashed

SWDB - Unified Software Database for DNF integration

history sqlite, yumdb and history persistor replaced by SWDB
yum/history classes rewritten into libdnf-swdb
see https://github.com/edynox/libdnf

Original commit tree was too long and caused problems when rebasing.
Find original tree here: https://github.com/edynox/dnf/tree/hif-swdb
I will try to keep both branches up to date for easier debugging until
PR will be merged.

[swdb]: rewritten transaction merging into libdnf

Transaction merging was done via obsoleted classes YumHistoryTransaction
and YumMergedHistoryTransaction which were significantly redundant with
SWDB Transaction implementation.

Transactions are now merged directly in SWDB using method merge.
i.e. T1.merge(T2),

[swdb]: trans with support + fixed history info

TRANS_WITH was missing from history info output.

Fixed package comparation and merged transaction IDs.

[swdb]: transaction comparison tests

Fixed tests for transaction comparison

Rewritten yumdb usage in base.py - introduced in upstream

[swdb]: change lib path for testing

[swdb]: refactor nvra to nevra in swdb calls

[swdb]: fix group_remove unit test and group reset

[swdb]: support for get erased reason

Introduced in rpm-software-management/dnf@3c661d6

[swdb]: cosmetic changes - package represenation

use str(pkg) instead of pkg.nevra

rename some variable names

[swdb]: refactor group is_installed to installed

For compatibility with original api + some cosmetic changes

[swdb]: port mark group feature to swdb

+ remove YumHistoryMergedTransaction from rollback command

[swdb]: reorganize database sources in DNF

Drop unused yum files and migrate SWDB sources out of the yum folder.

[swdb]: drop yum/packages.py

Replaced by DnfSwdbPkg method `match(pattern)`

[swdb]: API refactor - nevra -> DnfPackage

Hide internal swdb nevra binding from user

[swdb]: mark history.group as property

Load GroupPersistor lazily

[swdb]: API for asking if a group is installed (RhBug:1339623)

[swdb]: refactor reason - string -> enum

Use reason enumeration for simplier comparation and database access.

[swdb]: refactor package type to enum

Use enumeration for package type instead of string.

Fix ui_from_repo for transaction_with packages.

[swdb]: introduce dnf.db.types

Move Swdb specific types to separate file to avoid circular dependencies
between history and other source files.
