[PATCH v3 0/3] Add bblock helper scripts

[Julien Stephan <jstephan@baylibre.com>]

Hi all,

This is v3 from bblock script.

Improvement from v2:
* Add a function in bb.cooker to compute task signatures
* Replace the findSigInfo function by the new created one. This has the
  following advantages:
    * findSigInfo needs the task to be already built to get the siginfo
      file, meaning we cannot lock a recipe on a fresh build
    * we can now generate the signatures for all available task of a given
      recipe
* Check if a given task is already locked. If so, don't duplicate
  entry in bblock.conf

Limitations:
* Needs to taint tasks that are locked, to display a warning
* I may be still missing some checks on user input
* Silently does nothing if given task doesn't exist
* Silently does nothing when resetting a recipe that doesn't exist

I did some tests using qemux86-64 and qemuarm but I may be missing some
corner cases.

Improvement from V1:
* Signatures are now package architecture specific meaning that if you
  switch MACHINE, the lock sig will not be taken into account
* I added the -r option to unlock recipes
* I added a -d option to display the current bblock.conf
* Added an include directive for conf/bblock.conf inside bitbake.conf
* Added -t option to specify the tasks to lock/unlock

Limitations:
* I may be still missing some checks on user input
* I need to find a way to get the list of tasks ( by default still lock
  only the do_compile for now, unless -t is specified)
* Do not check if a particular recipe/task is already locked when trying
  to add lock. So entries may appear multiple times
* We still need the signature of the tasks to be already computed before
  locking. Need to find a way to generate it if missing

V2: https://lists.openembedded.org/g/openembedded-core/message/184697
V1: https://lists.openembedded.org/g/openembedded-core/message/184584

My branch is available here [1]

Cheers
Julien
