5844c8c7f0 Cleanups to the common.sys_info API
* Move get_all_subclasses out of sys_info as it is unrelated to system
  information.
* get_all_subclasses now returns a set() instead of a list.
* Don't port get_platform to sys_info as it is deprecated.  Code using
  the common API should just use platform.system() directly.
* Rename load_platform_subclass() to get_platform_subclass and do not
  instantiate the rturned class.
* Test the compat shims in module_utils/basic.py separately from the new
  API in module_utils/common/sys_info.py and module_utils/common/_utils.py

52449cc01a AnsiballZ improvements
Now that we don't need to worry about python-2.4 and 2.5, we can make
some improvements to the way AnsiballZ handles modules.

* Change AnsiballZ wrapper to use import to invoke the module
  We need the module to think of itself as a script because it could be
  coded as:

      main()

  or as:

      if __name__ == '__main__':
          main()

  Or even as:

      if __name__ == '__main__':
          random_function_name()

  A script will invoke all of those.  Prior to this change, we invoked
  a second Python interpreter on the module so that it really was
  a script.  However, this means that we have to run python twice (once
  for the AnsiballZ wrapper and once for the module).  This change makes
  the module think that it is a script (because __name__ in the module ==
  '__main__') but it's actually being invoked by us importing the module
  code.

  There's three ways we've come up to do this.
  * The most elegant is to use zipimporter and tell the import mechanism
    that the module being loaded is __main__:
    * 5959f11c9d/lib/ansible/executor/module_common.py (L175)
    * zipimporter is nice because we do not have to extract the module from
      the zip file and save it to the disk when we do that.  The import
      machinery does it all for us.
    * The drawback is that modules do not have a __file__ which points
      to a real file when they do this.  Modules could be using __file__
      to for a variety of reasons, most of those probably have
      replacements (the most common one is to find a writable directory
      for temporary files.  AnsibleModule.tmpdir should be used instead)
      We can monkeypatch __file__ in fom AnsibleModule initialization
      but that's kind of gross.  There's no way I can see to do this
      from the wrapper.

  * Next, there's imp.load_module():
    * https://github.com/abadger/ansible/blob/340edf7489/lib/ansible/executor/module_common.py#L151
    * imp has the nice property of allowing us to set __name__ to
      __main__ without changing the name of the file itself
    * We also don't have to do anything special to set __file__ for
      backwards compatibility (although the reason for that is the
      drawback):
    * Its drawback is that it requires the file to exist on disk so we
      have to explicitly extract it from the zipfile and save it to
      a temporary file

  * The last choice is to use exec to execute the module:
    * https://github.com/abadger/ansible/blob/f47a4ccc76/lib/ansible/executor/module_common.py#L175
    * The code we would have to maintain for this looks pretty clean.
      In the wrapper we create a ModuleType, set __file__ on it, read
      the module's contents in from the zip file and then exec it.
    * Drawbacks: We still have to explicitly extract the file's contents
      from the zip archive instead of letting python's import mechanism
      handle it.
    * Exec also has hidden performance issues and breaks certain
      assumptions that modules could be making about their own code:
      http://lucumr.pocoo.org/2011/2/1/exec-in-python/

  Our plan is to use imp.load_module() for now, deprecate the use of
  __file__ in modules, and switch to zipimport once the deprecation
  period for __file__ is over (without monkeypatching a fake __file__ in
  via AnsibleModule).

* Rename the name of the AnsiBallZ wrapped module
  This makes it obvious that the wrapped module isn't the module file that
  we distribute.  It's part of trying to mitigate the fact that the module
  is now named __main)).py in tracebacks.

* Shield all wrapper symbols inside of a function
  With the new import code, all symbols in the wrapper become visible in
  the module.  To mitigate the chance of collisions, move most symbols
  into a toplevel function.  The only symbols left in the global namespace
  are now _ANSIBALLZ_WRAPPER and _ansiballz_main.

8bdd04c147 Fix remote_tmp when become with non admin user (#42396)
* Fix tmpdir on non root become

 - also avoid exception if tmpdir and remote_tmp are None
 - give 'None' on deescalation so tempfile will fallback to it's default behaviour
   and use system dirs
 - fix issue with bad tempdir (not existing/not createable/not writeable)
   i.e nobody and ~/.ansible/tmp
 - added tests for blockfile case

* Revert "Temporarily revert c119d54"

This reverts commit 5c614a59a6.

* changes based on PR feedback and changelog fragment

* changes based on the review

* Fix tmpdir when makedirs failed so we just use the system tmp

* Let missing remote_tmp fail

If remote_tmp is missing then there's something more basic wrong in the
communication from the controller to the module-side.  It's better to
be alerted in this case than to silently ignore it.

jborean and I have independently checked what happens if the user sets
ansible_remote_tmp to empty string and !!null and both cases work fine.
(null is turned into a default value controller-side.  empty string
triggers the warning because it is probably not a directory that the
become user is able to use).

* Achievement Get: No longer need mock/generator.py
  * Now done via pytest's parametrization
  * Port safe_eval to pytest
  * Port text tests to pytest
  * Port test_set_mode_if_different to pytest

* Change conftest AnsibleModule fixtures to be more flexible
  * Move the AnsibleModules fixtures to module_utils/conftest.py for sharing
  * Testing the argspec code requires:
    * injecting both the argspec and the arguments.
    * Patching the arguments into sys.stdin at a different level

* More porting to obsolete mock/procenv.py
  * Port run_command to pytest
  * Port known_hosts tests to pytest
  * Port safe_eval to pytest
  * Port test_distribution_version.py to pytest
  * Port test_log to pytest
  * Port test__log_invocation to pytest
  * Remove unneeded import of procenv in test_postgresql

* Port test_pip to pytest style
  * As part of this, create a pytest ansiblemodule fixture in
    modules/conftest.py.  This is slightly different than the
    approach taken in module_utils because here we need to override the
    AnsibleModule that the modules will inherit from instead of one that
    we're instantiating ourselves.

* Fixup usage of parametrization in test_deprecate_warn

* Check that the pip module failed in our test

4b0aa1214c Ziploader
* Ziploader proof of concept (jimi-c)

* Cleanups to proof of concept ziploader branch:

* python3 compatible base64 encoding
* zipfile compression (still need to enable toggling this off for
  systems without zlib support in python)
* Allow non-wildcard imports (still need to make this recusrsive so that
  we can have module_utils code that imports other module_utils code.)
* Better tracebacks: module filename is kept and module_utils directory
  is kept so that tracebacks show the real filenames that the errors
  appear in.

* Make sure we import modules that are used into the module_utils files that they are used in.

* Set ansible version in a more pythonic way for ziploader than we were doing in module replacer

* Make it possible to set the module compression as an inventory var

This may be necessary on systems where python has been compiled without
zlib compression.

* Refactoring of module_common code:

* module replacer only replaces values that make sense for that type of
  file (example: don't attempt to replace python imports if we're in
  a powershell module).
* Implement configurable shebang support for ziploader wrapper
* Implement client-side constants (for SELINUX_SPECIAL_FS and SYSLOG)
  via environment variable.
* Remove strip_comments param as we're never going to use it (ruins line
  numbering)

* Don't repeat ourselves about detecting REPLACER

* Add an easy way to debug

* Port test-module to the ziploader-aware modify_module()

* strip comments and blank lines from the wrapper so we send less over the wire.

* Comments cleanup

* Remember to output write the module line itself in powershell modules

* for line in lines strips the newlines so we have to add them back in
