Some of the helper scripts used to run testcases contain some
constructs that are bashisms. Or at least which don't work on dash,
the minimal shell used as /bin/sh on recent Ubuntu systems.
This patch removes these constructs so that the testsuite will pass
"out of the box" on systems where /bin/sh is dash.

This patch modifies the dtc-checkfails.sh testcase wrapper so that
instead of testing just that dtc fails with a particular error code on
the sample input, it scans dtc's stderr output looking for a message
that dtc failed a specific check or checks. This has several advantages:
- It means we more precisely check dtc's checking behaviour
- It means we can check for generation of warnings using the
same script
- It means we can test cases where dtc should generate
multiple errors or warnings from different checks

This patch adds a group of testcases to check that dtc correctly
rejects trees with various structural errors.
To make things easier to test, we change dtc so that failing checks
(as opposed to other errors) result in exit code 2.
This patch also fixes an embarrasing bug uncovered by these new tests:
check_phandles() worked out if the tree's phandles were valid, then
throws that information away and returns success always.

This patch adds a handful of simple testcases for dtc. It adds a dts
file which should generate the same sample tree as is used for the
libfdt testcases, and tests invoking dtc on this dts, plus the
standard batch of libfdt cases on the resulting dtb, which effectively
checks that the dtb is correct.
Because the test framework assumes each testcase is an executable with
the right output conventions, we use a little shell script, dtc.sh, as
a wrapper around dtc itself. It simply invokes dtc and returns a PASS
or FAIL depending on whether dtc returned an error.
It's not much, but it's a start.
