Now we have the toolchain config fragments in the buildroot directory
itself, it is no longer necessary to fetch it from the toolchain URL.
The --toolchains-url option is renamed to --toolchains-csv.
The paths in the toolchains_csv file should be either absolute, or
relative to buildrootdir.
After this change, the script should be called from autobuild-run as:
subprocess.call([os.path.join(srcdir, "utils/genrandconfig"),
"-o", outputdir, "-b", srcdir,
"--toolchains-csv", kwargs['toolchains_csv']],
stdout=devnull, stderr=log)

This has a number of side-effects which must be handled.
The lines in minimal.config may be overridden by the random lines added
by amending the configuration, so is_toolchain_usable() shouldn't take
those into account, or indeed the random lines added. Therefore, make
a copy of the config before appending minimal.config and the random
lines. While we're at it, rename the variable to the more appropriate
toolchainconfig.
minimal.config sets BR2_INIT_NONE=y, but we really also want to test
with BR2_INIT_BUSYBOX=y. Therefore, add a random line to use the
busybox init system. We set its probability rather high. The
probabilities of systemd and eudev are increased since they're now
in the else branch of BR2_INIT_BUSYBOX, which halves the probability
that we even get there.
We now also generate configurations without busybox. Previously,
busybox was almost always selected due to BR2_INIT_BUSYBOX=y. Only if
systemd is selected there was a chance to build without busybox.
We now set BR2_SYSTEM_BIN_SH_NONE=y, the other /bin/sh options are
never tested. However, this is not really something that is relevant
to test in the autobuilders.

When outputdir is 'output' (the default), genrandconfig didn't work
correctly because it expects the configfile in outputdir, while
Buildroot puts it in the buildroot directory.
Fix this by explicitly checking if outputdir == buildrootdir/output.
Because abspath is used for both paths, string comparison works
reliably.

The path to the .config file is calculated in several places - replace
it with a single calculation, and pass configfile as an argument
to is_toolchain_usable and fixup_config. These functions also don't
need outputdir any more.
This makes it easier to fix the case when configfile is not in
outputdir.

The --instance argument is just an artifact of genrandconfig's
history as part of autobuild-run. It is much more logical to pass
the output directory and the buildroot directory as arguments, with
sane defaults.
This also allows us to remove the hack of creating a symlink in the
instance directory if it doesn't exist yet.
Note that the default outputdir 'output' doesn't work yet, because in
that case Buildroot will put the config file in the buildroot directory
instead of the output directory. This will be fixed in a follow-up
patch.
After this change, the script should be called from autobuild-run as:
subprocess.call([os.path.join(srcdir, "utils/genrandconfig"),
"-o", outputdir, "-b", srcdir,
"--toolchains-url", kwargs['toolchains_url']],
stdout=devnull, stderr=log)

The output of genrandconfig is currently very terse, which is annoying
for debugging the script or generally seeing what is going on. Also the
timing information added by log_write isn't very useful when the script
is used stand-alone.
In the new setup, (verbose) output goes to stdout and error output goes
to stderr. Also the "INFO: generate the configuration" message is
eliminated - it should go in the autobuild-run script.
We also add an explicit message when a toolchain can't be used after
the first defconfig, otherwise autobuild-run will just silently
restart.
Note that, since the output of make is no longer redirected to
/dev/null, we get one more message on stderr that will be recorded in
the autobuilder's log file: KCONFIG_SEED=0xXXXXXXXX.
This approach allows us to optimise the error handling to use
exceptions, where appropriate, which can be caught at the top level and
converted to an error message to stderr. This, in turn, allows us to use
subprocess.check_call, which eliminates a lot of conditions.

kwargs is a left-over from the use of docopt, it's better to use
argparse's Namespace object directly.
In addition, most functions use just one or two fields of args, so
these can just as well be passed directly as arguments to the function.
Particularly for outputdir it doesn't make sense to reconstruct it all
the time.

Warnings fixed:
E731 do not assign a lambda expression, use a def
-> urlopen_closing is defined with a def. urlopen is not used
elsewhere so inlined.
E302 expected 2 blank lines
E501 line too long
-> long lines due to a long string are NOT split
E701 multiple statements on one line (colon)
E722 do not use bare except'
-> use "except Exception", so KeyInterrupt and SystemExit are still
passed. We never intended to catch those.
E741 ambiguous variable name 'l'
-> variable name is replaced with the much more descriptive
toolchains_csv
E271 multiple spaces after keyword
E231 missing whitespace after ','

This script will be used by the autobuild-run script to generate the
configuration to test. It is put in the utils directory because it can
also be called directly to allow users to test things.
For now, it is a direct copy of the relevant functions from the
autobuild-run script. The only changes are:
- unneeded import statements are removed;
- code/decode wrappers are limited to decode_byte_list;
- __main__ handling is added.
For now, the only supported arguments are the ones needed for
autobuild-run. Follow-up patches will refactor things and also change
the way the script is called. In this version, it can be called from the
autobuild-run script as:
subprocess.call([os.path.join(srcdir, "utils/genrandconfig"),
"-i", str(kwargs['instance']),
"--toolchains-url", kwargs['toolchains_url']],
stdout=log, stderr=log)
