d8318feba1 patman: test_util: Use unittest text runner to print test results
The python tools' test utilities handle printing test results, but the
output is quite bare compared to an ordinary unittest run. Delegate
printing the results to a unittest text runner, which gives us niceties
like clear separation between each test's result and how long it took to
run the test suite.

Unfortunately it does not print info for skipped tests by default, but
this can be handled later by a custom test result subclass. It also does
not print the tool name; manually print a heading that includes the
toolname so that the outputs of each tool's tests are distinguishable in
the CI output.

7e4b66aa87 dtoc: Support reading a list of arguments
It is helpful to support a string or stringlist containing a list of
space-separated arguments, for example:

   args = "-n fred", "-a", "123";

This resolves to the list:

   -n fred -a 123

which can be passed to a program as arguments.

dd857ee761 dtoc: Allow deleting nodes and adding them in the same sync
This does not work at present, since the current algorithm assumes that
either there are no nodes or all nodes have an offset. If a node is new,

f6176651bc dtoc: Support adding subnodes alongside existing ones
So far we have only needed to add subnodes to empty notds, so have not
had to deal with ordering. However this feature is needed for binman's
expanded nodes, since there may be another node in the same section.

While libfdt adds new properties after existing properties, it adds new
subnodes before existing subnodes. This means that we must reorder the
nodes in the cached version, so that the ordering remains consistent.

Update the sync implementation to sync existing subnodes first, then
add new ones, then tidy up the ordering in the cached version. Update the
test to cover this behaviour.

Also improve the comment about property syncing while we are here.

a004f29464 binman: Tidy up _SetupDtb() to use its own temporary file
At present EnsureCompiled() uses an file from the 'output' directory (in
the tools module) when compiling the device tree. This is fine in most
cases, allowing useful inspection of the output files from binman.

However in functional tests, _SetupDtb() creates an output directory and
immediately removes it afterwards. This serves no benefit and just
confuses things, since the 'official' output directory is supposed to be
created and destroyed in control.Binman().

Add a new parameter for the optional temporary directory to use, and use a
separate temporary directory in _SetupDtb().
