Using off_t, at least, in DiskAdaptor layer is problematic because
torrent can contain under 2GiB files but total sum of those files may
exceed 2GiB limit, which makes off_t overflow in 32 bit system without
large file support. So we use int64_t in API. We'll check the file
length before download so that it does not exceed max off_t.
We added 2 macros A2_TEST_DIR and A2_TEST_OUT_DIR to pass tests in
`make distcheck`. A2_TEST_DIR refers to test directory. All output
files by unit tests are now created under A2_TEST_OUT_DIR directory.
Now the constructor of AbstractDiskWriter takes filename as an
argument and filename argument is removed from openFile(),
initAndOpenFile(), openExistingFile() interface. storeDir
member and its accessor functions are removed from DiskAdaptor
because it is not used anymore. size() member function of
DefaultDiskWriter, DirectDiskAdaptor and MultiDiskAdaptor now
can be called without opening file.
