use I3__FILE__ for DLOG, leave __FILE__ as is See also commit 0e752070ac2bed02d0858bbc450ddcee36e3b9b5, which broke source code listings in gdb unless you cd into i3/src. This should give us best of both :-).

Implement fake-outputs option (cmdline, cfg) for multi-monitor testing This kills the dependency on xdmx and makes the testsuite simpler and more flexible (in the output sizes / configurations).

Fix clang -Wextra except -Wunused-parameter. Cleared all warnings that occur when passing CFLAGS="-Wall -Wextra -Wno-unused-parameter" to make using clang 3.3 on Linux x86-64.

format **/*.c with clang-format-3.5 This has multiple effects: 1) The i3 codebase is now consistently formatted. clang-format uncovered plenty of places where inconsistent code made it into our code base. 2) When writing code, you don’t need to think or worry about our coding style. Write it in yours, then run clang-format-3.5 3) When submitting patches, we don’t need to argue about coding style. The basic idea is that we don’t want to care about _how_ we write the code, but _what_ it does :). The coding style that we use is defined in the .clang-format config file and is based on the google style, but adapted in such a way that the number of modifications to the i3 code base is minimal.
