GitWrapper._clone crashes occasionally but unfortunately
the root cause is not found yet. We need more info for debugging.

It is possible the user set a command to run in cloned Git repository,
but that command can ask for additional input. However Pungi will
capture all output, so if there is a prompt, it will never be shown.
In order to prevent confusion ("Did this hang?"), let's send empty
string to stdin of the program. That will cause any possible read to see
EOF immediately, which should cause an error that will then be reported
by Pungi to the user.
It is still possible the program will wait for input if it reads
directly from TTY. However in such case the prompt should hopefully also
be sent to TTY directly, so that possible confusion should be cleared.

If it fails, we can't really tell if it's a transient error or just too
old git client. Fall back to full clone immediately and retry there.

Before this patch, there were two code paths: either getting the only
the wanted content by calling git-archive, or cloning the repository and
copying the files.
Both these approaches have the downside of not allowing retriving
content from a specific git commit.
The workaround is to create a new empty repo (in the location to which
we cloned previously), fetching the specific commit to there and then
checking it out.
This supports any commit and works identically for any protocol. The
downside is that all files in that commit will be downloaded. It should
be no worse than the git-clone path, but can result in bigger transfers
than git-archive.
Unfortunately this is only supported with git 2.5+. On older version
fetch will fail with no error message (tested with 1.8.3). This can be
used to fall back to full clone. This fallback is clearly suboptimal in
terms of data transfer, but it should work reliably.

There is no guarantee that it will print any text. We don't even need
the output, we just print it to error log if there is a problem.

Instead use the definition from python-six. Once we drop Py 2 support
completely, we'll just swap underscores with dots.

This will automatically convert the output to unicode/str and we will
not have to worry about decoding ourselves.

When a file should be obtained from a git repository, allow running an
arbitrary command (like `make`) after clone but before copying the files
out. This only works for the Git backend.
The downside is that a clone is needed and we can no longer use `git
archive` to speed things up.

There are a couple arguments that are never used. We can just remove
them. This also fixes a bug where temporary files would be left
undeleted in tests.

In multiple situations we need to create temporary files or directories
that should not be preserved after compose is finished. Let's add
context managers that ensure these get cleaned up.
This fixes tests leaving garbage around in /tmp.

The address is no longer correct. We can just as well simply point to

Introduces a new metadata file to track arbitrary files added during the
extra-files phase. This file is placed in the root of each tree and is
called ``extra_files.json``. It is a JSON file containing a single
object, which contains a "header" key with an object describing the
metadata, and a "data" key, which is an array of objects, where each
object represents a file. Each object contains the "file", "checksums",
and "size" keys. "file" is the relative path from the tree root to the
extra file. "checksums" is an object containing one or more checksums,
where the key is the digest type and the value of that key is the hex
digest. Finally, the size is the size of the file in bytes.
For example:
{
"header": {"version": "1.0},
"data": [
{
"file": "GPL",
"checksums": {
"sha256": "8177f97513213526df2cf6184d8ff986c675afb514d4e68a404010521b880643"
},
"size": 18092
},
{
"file": "release-notes/notes.html",
"checksums": {
"sha256": "82b1ba8db522aadf101dca6404235fba179e559b95ea24ff39ee1e5d9a53bdcb"
},
"size": 1120
}

This will avoid confusion when the file can not be found, but previous
export from remote location worked well. In such case the log said:
Exporting from SCM...
Boom, no files found...
This commit changes it into:

Exporting file from current working dir...
Boom, no files found...

It should have raised NotImplementedError, but we better remove it
altogher since we are missing export_dir anyway.

Instead of spawning `cp x/* y` there is now Python code to the same
thing. This should help with debugging if something fails as the
traceback will be more informative (rather than saying a command
failed). As another benefit the tests get much simpler.
