[OE-core] [RFC PATCH 0/3] Shared state for all !

[Joshua Lock]

This is an RFC series, and for ease of review sent as against the Poky tree so
that it can be reviewed as a whole.

In Yocto #2041[2]  Mark reported an issue with reusing shared state as a
different user on the same machine.

Since the whole purpose of shared state is that it be shared I decided to dig
into this issue. I wanted to at least be able to use the shared-state cache of
a different user without error, even if all of the objects aren't actually used
(i.e. native, at least on the Edison branch I did most of the testing with).

This is an RFC mainly because it changes the permissions of created directories,
sstate files and siginfo files from what they have traditionally been.

There is more of the rhyme an reason in the patch commit headers and comments
but tl;dr bb.mkdirhier directories will be 0777 (rwxrwxrwx) with this patch, as
will all of the contents of sstate-cache (siginfo and tgz) files.

This is actually what one would expect from reading the Python API docs for
os.makedirs "The default mode is 0777 (octal)."[1] but not what actually happens
on most modern Linux systems thanks to umask.

Please review the following changes for suitability for inclusion. If you have
any objections or suggestions for improvement, please respond to the patches. If
you agree with the changes, please provide your Acked-by.

Regards,

Joshua
