This fixes many problems we were having with a dynamically growing
array because of the realloc (pointers inside the area which was
allocated were no longer valid as soon as the realloc moved the
memory to another address).
Again, this is a rather big change, so expect problems and enable
core-dumps.
Warning: This is not yet thoroughly tested, so be prepared to
encounter some segfaults. Please enable logging and coredumps,
so we can fix bugs quickly.
Commands are 'mark' and 'goto'. Both can be used either directly,
like 'mark a' and 'goto a', or interactively (just 'mark'). For
interactive mode, i3-input must be installed and in your PATH.
Use bn (normal), bp (1-px), bb (borderless) as commands to change the
border style of the currently focused window. Feel free to use i3-msg
to do this.
Also update documentation (manpage, userguide).
To make the code easier to read/write when checking if a client is
floating, introduce client_is_floating().
