The capabilities changed ('contextlevel' => CONTEXT_COURSE changed to
'contextlevel' => CONTEXT_MODULE) are:
* moodle/site:accessallgroups
* moodle/site:viewfullnames
* moodle/site:trustcontent
* moodle/site:viewuseridentity
This list came from reviewing the _get_extra_capabilities functions in
all core activities. They were all somewhat inconsistent, but I think it
makes sense that these capabilities are consistently overridable in all
activities. E.g. moodle/site:accessallgroups affects conditional
availability even if there is no other user of groups, and
moodle/site:viewuseridentity and moodle/site:viewfullnames affect the
logs report, if nothing else.
As a result of this, several _get_extra_capabilities functions are no
longer needed, and all the rest have been simplified.
