This is being added to resolve setscene race issues where we do have
particular dependencies required between setscene tasks. This allows
specific dependencies to be specified. This allows us to fix the races
in sstate with the useradd class in OE-Core.
Any tasks being depended upon have their reverse dependencies cleared to
ensure we don't have circular references.

When constructing the setscene inter-dependencies, we need to account for all task,
not just the last one found. This patch corrects this oversight and ensures all
dependencies are added, not just the first one found.

The existing looping code can mask an existing "found = True"
by forcing it to False each time. This can lead to dependency
lists not being fully searched and results in dependency errors.
An exmaple of this was the autobuilder building linux-yocto from
sstate but then rebuilding some of the recipe's tasks for no
apparent reason. Separating the logic into two variables solves this
problem since any "found = True" value is now always preserved.

If A depends upon B which depends upon C and the setscene for B
succeeds but C is going to get rebuilt, we should wait for C to
try and build A but currently we don't.
This is due to the timing of when we run the task_skip() as this
triggers other tasks to become buildable. This patch moves the timing
of that call to a more appropriate place allowing dependencies to
behave as expected.

The code which populates setscene_covered list was adding a task to the
covered list if all of the tasks that depend upon it were also covered;
however, this means that tasks that would have installed "runtime"
dependencies were being marked as covered also, e.g. gmp-native and
mpfr-native are needed by gcc-cross at runtime since they are shared
libraries that gcc links to, but their do_populate_sysroot tasks were
being marked as covered, resulting in failures later on if gcc-cross was
available from sstate but mpfr-native and gmp-native weren't.
Since we currently have no real way to handle runtime dependencies for
native packages, add a workaround which avoids marking tasks as covered
if one or more of their revdeps are from a different recipe.
Fixes [YOCTO #1536].

This fixes two problems:
a) Variables which were in the parent environment but not set as "export"
variables in the datastore could end up in the task environment
b) oe.environ.update() can't cope with the generator returned by
bb.data.exported_vars()
Whilst the updated code isn't as neat, it does do the expected thing,
sets the environment correctly and stops unwanted values leaking into
the task environment.

This patch, based on proof of concept code from Richard adds code to
bitbake to allow individual tasks to optionally specify their stamp
file using the stamp-base flag. This takes the same form as the STAMP
variable but can be specified on a per task basis.
Code is also added to runqueue to ensure that if two tasks share the
same stamp file, only one will be executed at once.
A significant usecase for this code is to share source code (${S})
between recipes where separate build directories (${B}) are used.

The umask for a task can now be set as:
task[umask] = 022
task[umask] = '022'
If specified as a text string, it must be octal. (This is due to
recipe parsing where it's always set to a string.)

JaMa reported issues where bitbake would rebuild things instead of using the
existing built tasks. This was tracked to a case where:
a) rm_work is uses
b) A depends on B
c) B has a version change (e.g. PR bump)
and A *and* B would then rebuild.
It turns out that rm_work was correctly turning stamp files into the correct
_setscene varients but bitbake was then ignoring them during setscene processing.
If the correct sstate checksumed files didn't exist, everything would seemingly
rebuild.
The fix is to check for existing *_setscene stamps and if present, honour them.
If "basichash" is enabled, the hash is included with the stamps so everything
should then function as intended.

If a build causes a real task to be run when the setscene task has already
run then it was possible for dependent packages to be rebuilding at the same
time as a rebuild of the packages they depended on, resulting in failures
when files were missing. This change looks in the setscene covered list and
removes anything where a dependency of the real task is going to be run (e.g.
do_install is going to be run even though the setscene equivalent of
do_populate_sysroot has already been run).
As an additional safeguard we also delete the stamp file for the setscene
task under these circumstances.

This patch is a quick proof of concept to show how source code could
be shared between recipes which use ${B} to have a separate build
directory compared to source directory ${S}.
Issues:
a) gcc uses sed and creates config files against ${S} which means
the directory should not be shared. Need to change the way that works.
b) Could be extended to cover eglibc except there is a patch applied
against nativesdk versions which again makes the source incompatible.
c) Need to clean up the layout in work-shared and make a directory level deeper
to ensure patch separation.
d) clean task does not remove stamps

Parsing the recipe in the parent before forking off the child worker
can mean the parent doesn't hit the idle loop and becomes a bottleneck
when lauching many short lived processes.
The reason we need this in the parent is to figure out the fakeroot
environmental options. To address this, add the fakeroot variables
to the cache and move recipe loadData into the child task.
For a poky-image-sato build this results in about a 2 minute speedup
(1.8%).

The server UI was reading 1024 bytes, then sleeping for 0.25 seconds. Since
most new LogRecord events are larger than this it leads to a build up of data
which is only processed slowly, leading to a bottleneck and a slow down of
all bitbake processes.
Thanks to Dongxiao Xu <dongxiao.xu@intel.com> for the great work in debugging
this. A large value has been left in for the read() command just to ensure some
fairness amongst process handling if a task tries to log truly huge amounts of
data to the server, or goes crazy and ensures the main loop doesn't stall.
