ee531d949c journal: add public API call sd_journal_get_events()
This function should be used when filling in "struct pollfd"'s .events
field for watching the journal. It will always return POLLIN for now,
but we should keep our options open to change this later on.

This mimics libsystemd-bus' sd_bus_get_events() call with the same
purpose.

2fa4092c28 util: make time formatting a bit smarter
Instead of outputting "5h 55s 50ms 3us" we'll now output "5h
55.050003s". Also, while outputting the accuracy is configurable.

Basically we now try use "dot notation" for all time values > 1min. For
>= 1s we use 's' as unit, otherwise for >= 1ms we use 'ms' as unit, and
finally 'us'.

This should give reasonably values in most cases.

cb0dac0548 time: add suppot for fractional time specifications
We can now parse "0.5s" as the same as "500ms". In fact, we can parse
"3.45years" correctly, too, and any other unit and fraction length.

d3b9e0ff4e build-sys: "link" libsystemd-id128 against libsd-daemon-internal
georgem> libsystemd-id128.so: undefined reference to `sd_listen_fds'

In some toolchains (--as-needed not used or not working), the
toolchain doesn't drop this dependency. It is introduced because
sd-id128.so is linked against sd-shared.la, and some functions therein
use libsystemd-daemon, but libsd-id128 doesn't use any of those
functions.

This results in no change in libsystemd-id128.so when the unused
symbols are properly stripped.

fda2c5d28b hostnamectl: if somebody invokes 'hostnamectl set-hostname' with a valid internet hostname unset the pretty name
If people are unaware or uninterested in the concept of pretty host
names, and simply invoke "hostnamectl set-hostname" for a valid internet
host name, then use this as indication to unset the pretty host name and
only set the static/dynamic one.

This also allows fqdn, hence "hostnamectl set-hostname www.foobar.com"
will just work if people really insist on using fqdns as hostnames.

768100efd5 fileio: write proper env var write-out code
This will properly escape all weird chars when writing env var files.
With this in place we can now read and write environment files where the
values contain arbitrary weird chars.

This enables hostnamed and suchlike to finally properly save pretty host
names with backlashes or quotes in them.

7f602784de util: rename parse_usec() to parse_sec() sinds the default unit is seconds
Internally we store all time values in usec_t, however parse_usec()
actually was used mostly to parse values in seconds (unless explicit
units were specified to define a different unit). Hence, be clear about
this and name the function about what we pass into it, not what we get
out of it.

7464b33d80 nss-myhostname: do not use _cleanup_
mss-myhostname wasn't working because of underlinking. Instead of
fixing the underlinking, just remove the use of _cleanup_ macros.

It is impolite to use our utility functions in modules designed to be
loaded by others. So cleanup macros which (at some point) call assert
which calls log_assert_failed, should not be used. Revert this part of
commit d73c3269c.

80cfe9e163 Do no isolate in case of emergency or severe problems
This patch changes local-fs.target and systemd-fsck to not use
"isolate" when going into emergency.
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=810722

The motivation is, that when something wents wrong, we should
keep everything as it is, to let the user fix the problem. When
isolating we stop a lot of services and therefore change the
system heavily so that it gets harder for the user to fix.

An example is a crypted partition. When the fsck in a crypted
partition fails, it previously used "emergency/start/isolate"
which stops cryptsetup. Therefore if the user tries to fsck
e.g. /dev/mapper/luks-356c20ae-c7a2-4f1c-ae1d-1d290a91b691
as printed by the failing fsck, then it will not find this
device (because it got closed).

So please apply this patch to let the user see the failing
situation.

Thanks!

[zj: removed dead isolate param from start_target().]

9607d9470e Always use our own MAX/MIN definitions
code in src/shared/macro.h only defined MAX/MIN in case
they were not defined previously. however the MAX/MIN
macros implemented in glibc are not of the "safe" kind but defined
as:

define MIN(a,b) (((a)<(b))?(a):(b))
define MAX(a,b) (((a)>(b))?(a):(b))

Avoid nasty side effects by using our own versions instead.

Also fix the warnings derived from this change.

[zj: - modify MAX3 macro to fix warning about _a shadowing _a,
     - do bootchart/svg.c too,
     - remove unused MIN3.]

aaf7eb81be shutdown: correctly wait for processes we killed in the killall spree
Previously we simply counted how many processes we killed and expected
as many waitpid() calls to succeed. That however is incorrect to do.

As we might kill processes that are not our immediate children, and as
there might be left-over processes in the waitpid() queue from earlier
the we might get more ore less waitpid() events that we expect.

Hence: keep precise track of the processes we kill, remove the ones we
get waitpid() for, and after each time we get SIGCHLD check if all
others still exist. We use getpgid() to check if a PID still exists.

This should fix issues with journald not setting journal files offline
correctly on shutdown, because we'd too quickly proceed from SIGTERM to
SIGKILL because some left-over process was in our waitpid() queue.

d7607eac63 core/socket: log errors when starting socket for this socket
When showing an error like 'Socket service not loaded', the
error won't show up in the status for the socket, unless it is
marked as SYSTEMD_UNIT=*.socket. Marking it as SYSTEMD_UNIT=*.service,
when the service is non-existent, is not useful.
