(cherry picked from commit 30438e42)

It's noisy because the edit profile page wants lots of helpfiles that haven't been written, and it's too close to a release to set about writing them.

In practice it would be more useful along with other debug lines that tell a translator that they need to translate certain help files.
(cherry picked from commit eaaea535)

Previously, get_helpfile_location would just look in $langroot/lang/$langname/... for the file, when it could be in $langroot/$plugintype/$plugintype/lang/$langname.

Spotted while testing David's previous patch.
(cherry picked from commit 07192741)

Allow language packs being installed outside the docroot. Fallback to
the English help file if the localized one is not found.
(cherry picked from commit 13e02387)

Small changes for fixes to (#3014) and (#3019) - exception handling for when curl is missing being the main one

Now they behave better, and respect the language pack search path. get_languages is cached.

Now the following locations are searched:

* docroot - the english language pack lives here
* directories in $dataroot/langpacks matching *.utf8
* anything on langpacksearchpaths

This makes $dataroot/langpacks the preferred place to install language packs, and makes langpacksearchpaths unnecessary for most people.

The upshot of all this is that it'll be much easier to install language packs - just download to $dataroot/langpacks and decompress :)

Make it so that plugin location doesn't need a / after it when specifying a location to search for a pieform template.

This is done by providing a function that form writers need to call to get the template directory. This function scans through the theme directories following the inheritance chain. This allows templates to be overrideable by theme.

Add function raise_memory_limit from Moodle, and use it to raise Mahara's default working memory to 32M.

This comes after a few complaints that certain RSS feeds would cause the View editor to die. Noticed by Derrin, mjmontagne and myself (on biobrio).

being installed.

Previously, we checked for table_exists, but that means we need DDL
which is very heavy. Now we check by catching the exception and ignoring
it if the system isn't installed.

Now no longer counts SET NAMES 'utf8' as a write. This means most pages
show as doing no writes, which is correct. 0 writes showed up as blank
in the footer, so tweaked the code appropriately.

If we don't, defaults for log levels and other such things aren't
specified, which can lead to problems when an error occurs while
connecting to the database.

This reverts commit 5780e905.

I'm going to fix installs now!

It's now only included on lib/upgrade.php.

One existing call to table_exists that was in safe_require has now been ditched as it's unnecessary.

The length of time since last access that tells whether a user has been online recently is configurable.

The block can also be disabled with a configuration parameter.

More work on profile views and three new blocktypes (myfriends/mygroups/myviews) to emulate current profile page TODO: - write wall blocktype - change install default profile view hook to add blocks - upgrade path (xmldb & migration) - blocktype and category and singleblockperview implementation

    - TESTING

this is meant to simplify both the creation of config.php (still from
config-dist.php) and the addition of new config variables that don't
have UI.  they now get added to config-defaults.php which is loaded
after config.php and database.

Perform validation on the parameters while we're in the area.
