Uninstalls a given list of disabled modules.
string[] $module_list: The modules to uninstall. It is the caller's responsibility to ensure that all modules in this list have already been disabled before this function is called.
bool $uninstall_dependents: (optional) If TRUE, the function will check that all modules which depend on the passed-in module list either are already uninstalled or contained in the list, and it will ensure that the modules are uninstalled in the correct order. This incurs a significant performance cost, so use FALSE if you know $module_list is already complete and in the correct order. Defaults to TRUE.
bool Returns TRUE if the operation succeeds or FALSE if it aborts due to an unsafe condition, namely, $uninstall_dependents is TRUE and a module in $module_list has dependents which are not already uninstalled and not also included in $module_list).
