Check if apc is disabled during ownCloud setup, if so enable it

[yodax]

I was able to reproduce the issue reported in the ownCloud 9.1.1 PR. If I change my config to disable apc, I get the same error message. Running the setup with this PR fixes the problem.

I check if it is explicitly disabled otherwise I do nothing, it might be enabled somewhere else.

editconf is idempotent so it should be safe to use it without the if block around it?

[yodax]

I put the if block there because the setting can be enabled in more than one place. My original config file didn't contain the setting. It is in another file.

I don't understand....

This option can be set in 2 places;

• /etc/php5/mods-available/apcu.ini
• /etc/php5/fpm/php.ini

I didn't want to build an option that sets it in both locations, just remove the explicit disable from the modules configuration. That's not the place where I would normally enable the setting. It is enabled by default. To enable it for fpm I would set it in that ini.

I don't think it will hurt to remove the if block, I just think it isn't pretty to do that.

Ahhha. Makes sense.
