Log a note when applying a taint to a task signature (e.g. when using
the -f or -C command line options) so that the user knows this has been
done.

If -f is specified, force dependent tasks to be re-run next time. This
works by changing the force behaviour so that instead of deleting the
task's stamp, we write a "taint" file into the stamps directory, which
will alter the taskhash randomly and thus trigger the task to re-run
next time we evaluate whether or not that should be done as well as
influencing the taskhashes of any dependent tasks so that they are
similarly re-triggered. As a bonus because we write this file as
<stamp file name>.taskname.taint, the existing code which deletes the
stamp files in OE's do_clean will already handle removing it.
This means you can now do the following:
bitbake somepackage
[ change the source code in the package's WORKDIR ]
bitbake -c compile -f somepackage
bitbake somepackage
and the result will be that all of the tasks that depend on do_compile
(do_install, do_package, etc.) will be re-run in the last step.
Note that to operate in the manner described above you need full hashing
enabled (i.e. BB_SIGNATURE_HANDLER must be set to a signature handler
that inherits from BasicHash). If this is not the case, -f will just
delete the stamp for the specified task as it did before.
This fix is required for [YOCTO #2615] and [YOCTO #2256].

Add a dependency to each variable on a filtered list of its varflags.
This is intended to catch things such as SRC_URI checksums, varflags
controlling extra functionality from classes (e.g. the recently updated
update-alternatives class in OE-Core), etc. and ensure their values
influence the sstate checksums.
There is an exclusion list which needs to be set via bitbake.conf
(BB_SIGNATURE_EXCLUDE_FLAGS), if this is not set then the functionality
is disabled. The existing vardepsexclude mechanism can also be used to
exclude undesired varflags, but they must be fully specified, e.g.:
do_patch[vardepsexclude] += "do_patch[someflag]"
Implements [YOCTO #2517].

Gathers a list of paths to have checksums calculated at parse time, and
processes these when calculating task hashes. Checksums are cached with
the file's current mtime. Thus, changing any local file in SRC_URI will
now cause the do_fetch taskhash to change, thus forcing a rebuild.
This change adds very roughly about an 8% increase in parse time (a few
seconds) and maybe a few seconds during runqueue generation, so a fairly
moderate performance hit.
Note that since paths are resolved at parse time, this will not force
a rebuild when files are introduced which would cause that resolved path
to be different - for example, where a machine-specific version of a file
was added without otherwise changing the recipe. This will need to be
handled in a future update.
Code to hook this into the signature generator was courtesy of
Richard Purdie <richard.purdie@linuxfoundation.org>.
Implements [YOCTO #2044].

the basehash when there is no taskhash, just like what dump_sigtask

The dataCache exposes much useful information to the singature generation code
for example its possible to figure out whether kernel dependencies are
important or not based on the RRECOMMENDS values.
We therefore pass this information to the handler and trust it to handle
any API changes in the dataCache structure.
For backwards compatibility, OE-Core is already updated to handle
the extra argument when it appears.

The actual task names are discounted for comparison of dependent tasks, only
the actual hashes are used. This updates the comparison code to account for
this change, attempting heuristic matching for more user friendly output but
falling back to showing the changed hashes directly. This avoids some confusing
output to users where it looked like tasks had changed when they had not and
actually had the same hash but a different taskname.

to be forced to specific values
We have a problem if we want to inject specific information into the variable
dependency code. There are cases for example where we want a dependency
on the value of X but it doesn't matter how X was constructed or what
dependencies it might have had, we only care about the absolute value.
With the current code, its near enough impossible to do this.
This patch adds such a mechanism so the user can trigger this with code like:
baselib[vardepvalue] = "${baselib}"
It also refactors some of the code so we do variable lookups once
instead of doing this in two different functions.

Without this patch the tash hash dependencies can be in a order
that is dependent upon directory/filesystem layout. With this
change the data is sorted the same regardless.
Without this the dependent hashes could be in different orders
on different systems and consequently final md5 hash would differ
as well even though nothing else changed.

When comparing sig files, if the recipe locations had changed, the
dependent tasks list would show as changed even if the actual hash
had not changed. This updates the code to only compare the base part
of the pathnames.
It also tweaks some of the output to add newlines to aid comparing
two lists of variables as it makes the location of the difference
clearer.

Given we use bb.error, not bb.fatal, here, it seems this was intended to be
non-fatal, yet we'd end up trying to concatenate None. Fix this by setting an
empty task to the empty string, for the purposes of hashing. Also str() the
value we get from the datastore, just in case something other than a string
was stored there.

Tracing down signature changes and dependencies is hard unless the complete task
chain can be evaultated. Since we have the data available at task exeuction
time, writing it to disk makes sense.
This change is suboptimal internal knowledge stamp_internal() has leaks into
make_stamp() and the concepts used by this code need revisiting but the change
brings enough usability benefit to warrant its inclusion despite that.

current bitbake-diffsigs simply print out the whole 'runtaskdeps' when there's mismatch, which
is not very readable. On the other hand, 'runtaskhashes' comparison is broken which assumes

from addition, removal or hash change.
