[libvirt] [PATCH v2 0/3] Implement mockup capabilities cache in QEMU tests

Since commit e8d55172544c1fafe31a9e09346bdebca4f0d6f9 qemu driver checks emulator capabilities during domain XML post-parse. However, test suite does not initialize it, therefore a condition to skip all checks if there is no cache supplied was added. This is actually a hack, whose sole purpose is to make existing test suite working. Additionally, it prevents from writing new tests for this particular functionality. This series solves this problem by implementing proper cache mockup in test suite. The main idea is to create a cache in standard way and put there pre-defined capabilities sets (which tests already have). In this implementation we introduce "test capability sets", which are named entities. virQEMUCapsCacheLookup() now has a test mode, which is enabled by setting qemuTestCapsName variable to the name of capability set which we want to use in current test. This is based on Martin Kletzander's idea to implement test mode with assertions. Currently, since name of capability set is different from /usr/bin/something, we will get errors if we try to do something with the host filesystem. This is achieved by setting cacheDir and libDir of our mockup cache to "/dev/null". The concept of using named capability sets allows us to further improve the test suite. Now it is possibe to get rid of hardcoded capability sets and replace them with XML files, readable by virQEMUCapsInitCached(). This will allow us to better exercise our capabilities parser. Taking this into account, qemuTestCapsCacheInsert() is actually temporary. It will not be needed any more when capabilities are moved to XML files. Additionally, some small refactoring is done, and common driver initialization and cleanup sequence is put into two functions: qemuTestDriverInit() and qemuTestDriverFree(). V1 => V2 - Fix also domainsnapshotxml2xmltest RFC => v1 - Major rework, almost everything changed.
