Subject: [PATCH] Fix salt.states.file.managed() for
 follow_symlinks=True and test=True (bsc#1199372) (#536)

When managing file /etc/test as follows:
> file /etc/test:
>   file.managed:
>     - name: /etc/test
>     - source: salt://config/test
>     - mode: 644
>     - follow_symlinks: True

and with /etc/test being a symlink to a different file, an invocation of
"salt-call '*' state.apply test=True" can report that the file should be
updated even when a subsequent run of the same command without the test
parameter makes no changes.

The problem is that the test code path doesn't take correctly into
account the follow_symlinks=True setting and ends up comparing
permissions of the symlink instead of its target file.

The patch addresses the problem by extending functions
salt.modules.file.check_managed(), check_managed_changes() and
check_file_meta() to have the follow_symlinks parameter which gets
propagated to the salt.modules.file.stats() call and by updating
salt.states.file.managed() to forward the same parameter to
salt.modules.file.check_managed_changes().

Fixes #62066.

[Cherry-picked from upstream commit
95bfbe31a2dc54723af3f1783d40de152760fe1a. The backport drops
tests/pytests/unit/modules/file/test_file_check.py because the test
requires unavailable patching of loader modules.]
