Move network-related journal programs to src/journal-remote/
Directory src/journal has become one of the largest directories,
and since systemd-journal-gatewayd, systemd-journal-remote, and
forthcoming systemd-journal-upload are all closely related, create
a separate directory for them.
If a file was opened for writing, and then closed immediately without
actually writing any entries, on subsequent opening, it would be
considered "corrupted". This should be totally fine, and even in
read mode, an empty file can become non-empty later on.

sd-dhcp-client: make request broadcasts opt-in
It appears there is no good way to decide whether or not broadcasts should be enabled,
there is hardware that must have broadcast, and there are networks that only allow
unicast. So we give up and make this configurable.
By default, unicast is used, but if the kernel were to inform us abotu certain
interfaces requiring broadcast, we could change this to opt-in by default in
those cases.

timesyncd: only listen to clock changes when connected
This reverts previous commit and applies a different fix.
manager_clock_watch() callback calls manager_send_request() to kick
off a resync. We can only do that when we're actually connected to
something. It is not useful to setup the callback from manager_new().
Now the callback will be dropped in manager_connect() and requested
in manager_begin().
networkd: dhcp add vendor class indentifier option 60
Vendor Class Identifier be used by DHCP clients to identify
their vendor type and configuration. When using this option,
vendors can define their own specific identifier values, such
as to convey a particular hardware or operating system
configuration or other identifying information.
Vendor-specified DHCP options—features that let administrators assign
separate options to clients with similar configuration requirements.
For example, if DHCP-aware clients for example we want to separate
different gateway and option for different set of people
(dev/test/hr/finance) in a org or devices for example web/database
servers or let's say in a embedded device etc and require a different
default gateway or DNS server than the rest of clients.
path-lookup: don't make ~/.local/share/systemd/user a symlink
We already encourage upstreams to keep the default configuration
separate from user customizations for software that is installed in
the system location. Let's allow that separation also for software
that is installed in the home directory.

build-sys: Do not distribute generated emergency.service
It is already in nodist_systemunit_DATA and if it is
shipped, it contains the hardcoded path to systemctl
which will cause it to fail to start when
rootprefix != prefix and rootbindir != bindir.
src/core/org.freedesktop.systemd1.policy.in.in depends on values which
are specified at configure time, so we cannot ship the corresponding
policy file in the tarball.
Since we need to regenerate one policy file, we might as well generate
them all.

sd-event: always call epoll_ctl() on mask-updates if edge-triggered
A call to sd_event_source_set_io_events() skipps calling into the kernel
if the new event-mask matches the old one. This is safe for
level-triggered sources as the kernel moves them onto the ready-list
automatically if events change. However, edge-triggered sources might not
be on the ready-list even though events are present.
A call to sd_event_source_set_io_events() with EPOLLET set might thus be
used to just move the io-source onto the ready-list so the next poll
will return it again. This is very useful to avoid starvation in
priority-based event queues.
Imagine a read() loop on an edge-triggered fd. If we cannot read data fast
enough to drain the receive queue, we might decide to skip reading for now
and schedule it for later. On edge-triggered io-sources we have to make
sure it's put on the ready-list so the next dispatch-round will return it
again if it's still the highest priority task. We could make sd-event
handle edge-triggered sources directly and allow marking them ready again.
However, it's much simpler to let the kernel do that for now via
EPOLL_CTL_MOD.
The check only cares about whether the module is installed, not enabled.
But installation we should know anyway, after all we ship the module
with systemd these days...

units: make ExecStopPost action part of ExecStart
Currently after exiting rescue shell we isolate default target. User
might want to isolate to some other target than default one. However
issuing systemctl isolate command to desired target would bring system
to default target as a consequence of running ExecStopPost action.
Having common ancestor for rescue shell and possible followup systemctl
default command should fix this. If user exits rescue shell we will
proceed with isolating default target, otherwise, on manual isolate,
parent shell process is terminated and we don't isolate default target,
but target chosen by user.
