List of changes:
* New OOP API using PHP namespace \core\session\.
* All handlers now update the sessions table consistently.
* Experimental DB session support in Oracle.
* Full support for session file handler (filesystem locking required).
* New option for alternative session directory.
* Official memcached session handler support.
* Workaround for memcached version with non-functional gc.
* Improved security - forced session id regeneration.
* Improved compatibility with recent PHP releases.
* Fixed borked CSS during install in debug mode.
* Switched to file based sessions in new installs.
* DB session setting disappears if DB does not support sessions.
* DB session setting disappears if session handler specified in config.php.
* Fast purging of sessions used in request only.
* No legacy distinction - file, database and memcached support the same functionality.
* Session handler name included in performance info.
* Fixed user_loggedin and user_loggedout event triggering.
* Other minor bugfixing and improvements.
* Fixed database session segfault if MUC disposed before $DB.
Limitations:
* Session access time is now updated right after session start.
* Support for $CFG->sessionlockloggedinonly was removed.
* First request does not update userid in sessions table.
* The timeouts may break badly if server hosting forces PHP.ini session settings.
* The session GC is a lot slower, we do not rely on external session timeouts.
* There cannot be any hooks triggered at the session write time.
* File and memcached handlers do not support session lock acquire timeouts.
* Some low level PHP session functions can not be used directly in Moodle code.
This commit moves user agent related functionality out of several
core libraries and combines it into a more manageable class.
All core uses are converted and functions deprecated in favor
of the new class.

Better performance, more reliable, completely self contained,
more validation and full backwards compatibility.
This will also allow us to implement ignoring of plugins.
get_plugin_list was calling clean_param($pluginname, PARAM_PLUGIN) a
lot (600+ times per page), and that is much slower than you would guess.
A specific function for this case, (which we then also use from
clean_param) is a performance win.
I also broke the unit tests into more, smaller, named tests, so that
when things start failing, more tests are run, and it is clearer what
the problem is.
In a couple of cases, I adjusted the $ideal lenght in the test. A
careful counting of the characters in the test input (added as comments)
suggests that the new values make for better tests.
This change removes the "0 bytes" option from the get_max_upload_sizes list
and replaces it with "Course limit (X)" or "Site limit (X)" (whichever is smaller).
This means we can remove all custom handling in the modules that were removing and
adding these options. It only affects pages that pass valid options for sitelimit and
courselimit - so admin pages will work correctly.
It also orders the list so the course/site limit options will be first
(as it will be the largest).
AMOS START
REM [courseuploadlimit, core] has been parameterized to get [uploadlimitwithsize, core]
AMOS END
The logic change here allows for multiple dots to be part
of a file name or folder name. Most Unit Tests have not
been altered and reflect the exact logic as it was before.
usergetdate should return consistent values for different timezone. There are
two return path
1. If timezone is servertime, it returns getdate
2. If timezone other then servertime, it use gmstrftime, which returns string and
values with leading zero.
In second case, leading zero's are removed and values are type casted. One major fix
is with yday, getdate returns 0 through 365, whereas %j returns 001 through 366. This
has been fixed as well.
Includes:
* constants refactoring
* reworked db table init
* support for $CFG->debug = -1
* functional DB tests
* fixed $DB->get_indexes() to not throw exceptions when table does not exist
* fix handling of user passwords in test db
* add debug info to exception messages
* removed unnecessary PHP debug errors from mathslib
* fixed @error suppression in get_string
* fixed PHPUnit error handler setup
* added timezone info to default install
