Michael Stapelberg 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).

Interestingly, compilation was only broken on some systems apparently

Quentin Glidic c7029a5e21 common.mk: Introduce I3_*FLAGS
CPPFLGES, CFLAGS and LDFLAGS should be user variables
We now provide default flags but use I3_*FLAGS flags for our own needed
flags

Also reoder lib flags a bit

Michael Stapelberg 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.
