core: track why unit dependencies came to be
This replaces the dependencies Set* objects by Hashmap* objects, where
the key is the depending Unit, and the value is a bitmask encoding why
the specific dependency was created.
The bitmask contains a number of different, defined bits, that indicate
why dependencies exist, for example whether they are created due to
explicitly configured deps in files, by udev rules or implicitly.
Note that memory usage is not increased by this change, even though we
store more information, as we manage to encode the bit mask inside the
value pointer each Hashmap entry contains.
Why this all? When we know how a dependency came to be, we can update
dependencies correctly when a configuration source changes but others
are left unaltered. Specifically:
1. We can fix UDEV_WANTS dependency generation: so far we kept adding
dependencies configured that way, but if a device lost such a
dependency we couldn't them again as there was no scheme for removing
of dependencies in place.
2. We can implement "pin-pointed" reload of unit files. If we know what
dependencies were created as result of configuration in a unit file,
then we know what to flush out when we want to reload it.
3. It's useful for debugging: "systemd-analyze dump" now shows
this information, helping substantially with understanding how
systemd's dependency tree came to be the way it came to be.

basic/hashmap: add cleanup of memory pools (#7164)
It was dropped in
89439d4fc0d29f04ac68432fd06ab84bc4e36e20. As a result, every
process that uses a hashmap allocates and then leaks the hashmap mempools.
The mempools are only allocated in the main thread, but we don't know where
the memory is used.
So let's check if we are the last thread and free the mempools then. This is
fairly heavy, because /proc/self/status has to be opened and parsed, but we do
it only when compiled for valgrind, i.e. not by default, and compared to running
under valgrind or asan, the extra cost is acceptable. The big advantage is that
we don't have to think or filter out this false positive.
As a micro-opt, cleanup is attempted only in the main thread. We could allow
any thread to check if it is the last one and perform cleanup, but that'd mean
that we'd have to _do_ the check in every thread. We don't use threads like
that, our non-main threads are always short-lived, so let's just accept the
possibility that we'll leak memory if a thread survives. The check is also
non-atomic, but it's called in a destructor of the main thread _and_ we do
cleanup only when there are no other threads, so the risk of some library
suddenly spawning another thread is very low. All in all, this is not perfect,
but should work in 999‰ of cases.

umount: always use MNT_FORCE in umount_all() (#7213)
The linux umount2() systemcall accepts a MNT_FORCE flags
which some filesystems honor, particularly FUSE and various
network filesystems such as NFS.
These filesystems can sometimes wait for an indefinite period
for a response from an external service, and the wait if
sometimes "uninterruptible" meaning that the process cannot be
killed.
Using MNT_FORCE causes any such request that are outstanding to
be aborted. This normally allows the waiting process to
be killed. It will then realease and reference it has to the
filesytem, this allowing the filesystem to be unmounted.
If there remain active references to the filesystem, MNT_FORCE
is *not* forcefull enough to unmount the filesystem anyway.
By the time that umount_all() is run by systemd-shutdown, all
filesystems *should* be unmounted, and sync() will have been
called. Anything that remains cannot be unmounted in a
completely clean manner and just nees to be dealt with as firmly
as possible. So use MNT_FORCE and try to explain why in the
comment.
Also enhance an earlier comment to explain why umount2() is
safe even though mount(MNT_REMOUNT) isn't.

man: update documents for RuntimeDirectory= and friends
Yu Watanabe [Wed, 8 Nov 2017 06:50:58 +0000 (15:50 +0900)]
core/execute: do not create RuntimeDirectory= under private/ sub-directory
RuntimeDirectory= often used for sharing files or sockets with other
services. So, if creating them under private/ sub-directory, we cannot
set DynamicUser= to service units which want to share something through
RuntimeDirectory=.
This makes the directories given by RuntimeDirectory= are created under
/run/ even if DynamicUser= is set.
Fixes #7260.

core: ReadWritePaths= and friends assume '+' prefix when BindPaths= or freinds are set
When at least one of BindPaths=, BindReadOnlyPaths=, RootImage=,
RuntimeDirectory= or their friends are set, systemd prepares
a namespace under /run/systemd/unit-root. Thus, ReadWritePaths=

So, let's assume '+' prefix when one of them are set.
