LocalFile::lock() held an explicit DB transaction open while a
potentially slow file backend operation was in progress, causing
production errors.
Instead, protect write operations with non-blocking locks. If a file is
locked, report the failure to the user. Like an edit conflict, informing
the user is appropriate in most cases. For example, if two admins try to
delete the same file at the same time, only one should succeed, and the
second does not need to wait for the first.
In upgradeRow(), locks were used to protect operations which read from a
file and write the result back to the database. The lock was supposed
to prevent overwriting of fresh data with stale data. Use a timestamp
check instead.

(Everywhere except includes/PHPVersionCheck.php)
(Then, manually fix some line length and indentation issues)
Then manually reviewed the replacements for cases where confusing
operator precedence would result in incorrect results
(fixing those in I478db046a1cc162c6767003ce45c9b56270f3372).

phpdbg is a gdb-style debugger for PHP that is run from the command
line. However, it has a different PHP_SAPI value, so it was impossible
to run maintenance scripts with it (until now).
To avoid having to check both PHP_SAPI values in a bunch of places,
introduce wfIsCLI() to easily check whether running from the
command-line or not.
We're (CI team) interested in generating code coverage with phpdbg
instead of xdebug, hence this patch.
