e68a8dd86c shm-logging: implement i3-dump-log -f (follow) 
This changes the SHM log format, it doesn’t use 0-bytes to separate
entries anymore. Instead of using lots of printf() calls in i3-dump-log,
we now do precisely one big write().

So, to be clear: i3-dump-log and i3 both need to be upgraded.
Mismatching versions will lead to garbage output (no crashes of i3, just
garbage output).

The -f flag uses an inter-process pthread_cond_t in the shared memory
header to broadcast the arrival of new messages to all i3-dump-log
processes. This internally uses futexes and thus doesn’t even mean a
kernel call in most cases. inter-process pthread_cond_ts require NPTL
(the Native Posix Thread Library, introduce in Linux 2.6).

884627ef20 use I3__FILE__ for DLOG, leave __FILE__ as is 
See also commit 0e752070ac, which broke
source code listings in gdb unless you cd into i3/src. This should give
us best of both :-).

70ec3867fe clean up zero-byte logfile on immediate exit 
Otherwise, a zero-byte log file stays behind after every call to `i3
--get-socketpath`. Also, replace "return" calls with more explicit "exit"
calls.

Before:

$ ls -ld /tmp/i3* | wc -l; \
  repeat 10 i3 --get-socketpath >/dev/null; \
  ls -ld /tmp/i3* | wc -l
1
11

Now:

$ ls -ld /tmp/i3* | wc -l; \
  repeat 10 i3 --get-socketpath >/dev/null; \
  ls -ld /tmp/i3* | wc -l

0e752070ac explicitly set filenames to $(basename __FILE__) 
This makes the debug log a bit more readable, especially since commit

bdc078914b i3: Replace loglevels by a global debug logging 
File-limited were not used nor really useful
Besides, they are painful to maintain in Makefile rules compared to the
benefit

206b96202c Use (void) instead of () for functions without args (Thanks fernandotcl) 
See also:
http://article.gmane.org/gmane.linux.kernel/1268792

The C compiler will handle (void) as "no arguments" and () as "variadic
function" (equivalent to (...)) which might lead to subtle errors, such
as the one which was fixed with commit 0ea64ae4.

dee7c07ad2 shmlog: store meta information in the buffer itself, store path as X11 atom 
This makes i3-dump-log completely independent of a running i3 instance.

e65ee63763 Implement logging to a SHM ringbuffer 
This feature is automatically enabled when running a debug version of i3.
The logfile will use 1% of your physical RAM size, but at max 25 MiB.

f09d9a4c37 log: use localtime_r instead of localtime 
localtime_r does not have the side-effect of behaving like it called tzset(),
in particular it will save one stat(/etc/localtime) syscall. This is not a big
deal, but it makes the strace output cleaner and thus more useful :).

22882f4e89 Bugfix: Initialize verbose to 'false' (Thanks tilman) 
Verbosity was set to 'true' when we started the tree branch.
We forgot to set it back to 'false' :-).

c145f7e529 first step of the big refactoring ("tree" branch). 
From here on, we can track changes. It made no sense to put the
development up to this point into git.
