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).

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
1

Besides, they are painful to maintain in Makefile rules compared to the

Use (void) instead of () for functions without args (Thanks fernandotcl)

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

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 :).

Verbosity was set to 'true' when we started the tree branch.
We forgot to set it back to 'false' :-).
