Don't write to config file if `config_is_read_only` is set
Also don't write to cache in this case to prevent cache and config file
being out of sync.

We read config.php an awefull lot of times. So it only makes sense to
kill this as much as wel can.

Format control structures, classes, methods and function
To continue this formatting madness, here's a tiny patch that adds
unified formatting for control structures like if and loops as well as
classes, their methods and anonymous functions. This basically forces
the constructs to start on the same line. This is not exactly what PSR2
wants, but I think we can have a few exceptions with "our" style. The
starting of braces on the same line is pracrically standard for our
code.
This also removes and empty lines from method/function bodies at the
beginning and end.

When installing ownCloud the first time the first thing that an admin saw was an error message:
> Error PHP touch(): Unable to create file owncloud.log because Permission denied at /var/www/owncloud/lib/private/log/owncloud.php#48
Or something related. This lead to a lot confusion as can be seen in our forum and in our issue tracker. This change should make the error messages disappear in most cases (e.g. where the file can actually be written). To test this:
1. On master install ownCloud and check owncloud.log => Error message
2. On this branch install ownCloud and check owncloud.log => No error message
Fixes https://github.com/owncloud/core/issues/13736 and https://github.com/owncloud/core/issues/12893
Use `file_exists` to verify that config file exists
There might be the case that `fopen($file, 'r')` returns false and thus ownCloud might believe that the config file is empty and thus potentially leading to an overwrite of the config file.
This changeset introduces `file_exists` again which was used in ownCloud 5 where no such problems where reported and should not be affected by such problems.

Try to read the file only instead of trying to touch
The permissions are already catched properly on the installation so we just have to check whether the file is readable to prevent fatal errors from happening.

add function to invalidate one opcache file, use it if possible #9885
Issue #9885 appears to be triggered by ownCloud invalidating the entire
PHP opcache. Testing indicates it can be avoided by only invalidating the
single file that was written from the opcache, instead of clearing the
whole thing. In general it is more efficient to invalidate only the single
file that was changed, rather than the whole cache.
This adds a deleteFromOpcodeCache() function which invalidates a single
file from the opcache if possible, returning true if the underlying
function returns true (which may mean 'success', or 'file does not exist',
or 'file exists but is not in opcache', all of which are OK to treat as
good for our purposes). It also changes writeData() in config.php to try
using deleteFromOpcodeCache() and only fall back on clearOpcodeCache() if
that fails.
This adds a file lock to the config in hope that this prevents race conditions as reported in https://github.com/owncloud/core/issues/11070
Testplan:
- [ ] Delete config.php and make it read-only => Error is thrown that it is not writeable
- [ ] Installation still works
- [ ] Changing config settings works (i.e. using the SMTP config switches in the administration menu)
- [ ] Your PC didn't blow up
- [ ] Installing the news app and the "Disable AppCode checker" app did not destroy your installation
Only skip the main config
Otherwise read only additional configs might not be processed
Test on tmpdir
