There were basically two problems, which are demostrated by
the new test users u7 and u8 in the unit test.
1. There was a problem if a role was overridden in a context above the
one where it was assigned. E.g. User has teacher role in a course, and
there is a role override in the course-category context. That was being
ignored.
2. Problems with the handling of PROHIBITs. It should be the case that
if there is a PROHIBIT in force, then it cannot be overridden by another
role, or by a role override. However, this was not working in all cases.
Also, I had to add comments to the unit test so that I could understand
it. Hopefully these will be hepful to other developers too.
This change removes the complex and partial loading of role definition data for users.
It is replaced by keeping one system-wide definition for each role in MUC.
This is cheaper to regenerate as it avoids complex database queries (repeated LEFT JOIN to context).
Memory usage is kept low thanks to array CoW for each user access data.
Refactor similar SQL generation code from get_users_by_capability
and get_enrolled_uses to make get_with_capability_sql.
Modified files: accesslib.php, enrollib.php, grouplib.php, new tests.
The function get_role_users() requires the caller to include the $sort fields in
the $fields argument. On PostgreSQL this will cause the function to fail when
the default $sort fields aren't part of the requested fields. The behavior of
the function is augmented to add the $sort fields to $fields if they are not
already present.
* Upgrades existing data so that the groupmembersonly option is
replaced with equivalent data for the new availability API.
* Removes the database field and admin setting used for
groupmembersonly.
* Changes core modinfo library to remove/deprecate groupmembersonly
data and functions.
* Changes other core library files to remove groupmembersonly
references.
Includes deprecation of several functions, listed in lib/upgrade.txt.
When different ID's are set for each sequence a number
of unit test failures appear. They have been corrected
to allow unit tests to pass with the new generator in place.

instance is has been used instead of cmid. This works as all id's are 1
in most cases, but not always.
accesslib_clear_all_caches_for_unit_testing was updated to clear the
$USER->access cache which would fail test when the wrong user's data was used.
