Check:

- a message is collected;
- the daemon does not issue a warning message on startup.
When the .conf file version does not match the package version a warning
message shows up on serial on every boot. This message is generated by
syslog-ng before it is running, so it is not logged to

Some test cases don't use a full build as setup, so split the build()
method into configure() and build().
It allows a test case to perform configuration at the setup stage and
the build inside the test itself.
Call this new method just before build in the BRTest base class, to keep
the current behavior for existing test cases.
This change will be needed when adding a common class to test the git

Currently, some packages may register hooks to be run just before and
just after the generic tarball image is generated, because they need to
prepare the filesystem for read-only or read-write operation.
However, this means that, if any of the hooks or the image generation
fails, the target directory is left in a dangling, inconsistent state.
We fix that by doing a copy of target/, run the hooks on that copy,
generate the generic tarball image out of that, and get rid of the copy.
This way, we can guarantee consistency of the target directory, and we
can even ditch support for post-fs hooks (those that restore target/).

It needs mkzftree from zisofs-tools, so we add a dependency to it, and
we call that one explicitly (to avoid using the one from the host in
PATH).
It also needs the the uncompressed kernel image, but because it is
already in target/ so it gets compressed by mkzftree. We have two
options:
- compress everything but the kernel image,
- compress everything, kernel included, and recopy it later.
We choose the latter, because it is the simplest solution. So, we always
define the kernel-copy hook, but only register it when needed.
Finally, it needs a kernel with support for transparent
(de)compression, so we update the existing test config.

Move the strip out of leading spaces in defconfig fragments from the
BRTest class to the Builder class. It actually postpones the strip out,
consequentially allowing test cases to post-process the defconfig in
their own __init__ before calling the __init__ method from BRTest.
Moving this code to the Builder class also allows any new test class
that inherits from BRTest to reuse the same code even if the new class
overrides the setUp method.
At same time, prepend a newline to the jlevel handling otherwise it
would stop working for defconfig fragments that don't end in a newline.

Since commit cf3cd4388a the -j option is
silently ignored.
The configuration lines are processed using '\n'.join().
This function adds intervening occurrences of the separator, but the
resulting string does not end at a separator.
>>> "n".join(["a","b"])
'anb'
It results in a defconfig that does not end in a newline.
When BR2_JLEVEL is added by -j logic to the defconfig it ends up
concatenated to the last line of the defconfig.
BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_ARM=yBR2_JLEVEL=7
The resulting .config has the default BR2_JLEVEL=0.
Instead of just workaround this problem by adding a newline before
BR2_JLEVEL when -j is used, make the defconfig to end in a newline since
it is a more future-proof solution.
