test-compress-benchmark: fix argument parsing on 32bit
The patch is not minimal, but a function to parse size_t is probably
going to come in handy in other places, so I think it's nicer to define
a proper parsing function than to open-code the cast.
- Move gcrypt.h include inside grcrypt-util.h.
- Allow gcrypt-util.[ch] to be compiled even without gcrypt.
This allows the logic in files using gcrypt to be simplified.
- Fix compilation of systemd-resolve without gcrypt.
systemd-resolved already supported that.

core: update invoke_sigchld_event() to handle NULL ->sigchld_event()
After receiving SIGCHLD, one of the ways manager_dispatch_sigchld() maps the
now zombie $PID to its unit is through manager_get_unit_by_pid_cgroup() which
reads /proc/$PID/cgroup and looks up the unit associated with the cgroup path.
On non-unified cgroup hierarchies, a process is immediately migrated to the
root cgroup on death and the cgroup lookup would always have returned the unit
associated with it, making it rather pointless but safe. On unified hierarchy,
a zombie remains associated with the cgroup that it was associated with at the
time of death and thus manager_get_unit_by_pid_cgroup() will look up the unit
properly.
However, by the time manager_dispatch_sigchld() is running, the original cgroup
may have become empty and it and its associated unit might already have been
removed. If the cgroup path doesn't yield a match, manager_dispatch_sigchld()
keeps pruning the leaf component. This means that the function may return a
slice unit for a pid and as a slice doesn't have ->sigchld_event() handler,
calling invoke_sigchld_event() on it causes a segfault.
This patch updates invoke_sigchld_event() so that it skips calling if the
handler is not set.

core: update populated event handling in unified hierarchy
Earlier during the development of unified hierarchy, the populated event was
reported through by the dedicated "cgroup.populated" file; however, the
interface was updated so that it's reported through the "populated" field of
"cgroup.events" file. Update populated event handling logic accordingly.

cgroup2: use new fstype for unified hierarchy
Since Linux v4.4-rc1, __DEVEL__sane_behavior does not exist anymore and
is replaced by a new fstype "cgroup2".
With this patch, systemd no longer supports the old (unstable) way of
doing unified hierarchy with __DEVEL__sane_behavior and systemd now
requires Linux v4.4 for unified hierarchy.
Non-unified hierarchy is still the default and is unchanged by this
patch.

lldp.h contains definitions of LLDP types, subtypes and capabilities which

test-copy: use correct data type for max_bytes
copy_bytes() and the comparisons in test_copy_bytes_regular_file() expect an
uint64_t, not a size_t. On 32 bit architectures the latter is 32 bit, leading
to truncation errors.
journal-upload doesn't really need microhttpd to run.
Without the dependency, we can cross compile systemd
without microhttpd and get the uploader part of the
remote logging.
basic/missing: move syscall definitions to basic/missing_syscall.h
We have a bunch of syscall wrapper definitions and it's easier to
see that they follow the same pattern if they are not interspersed
with other defines.
Change the wrappers to be uniform:
- if __NR_XXX is not defined, do not bother to call the syscall,
and return -1/ENOSYS immediately.
- do not check __NR_XXX defines if we detect the symbol as defined,
since we don't need them anyway
- reindent stuff for readability
New file basic/missing_syscall.h is included at the end of missing.h
because it might make use of some of the definitions in missing.h.
For btrfs, c_f_r() is like BTRFS_IOC_CLONE which we already used, but also
works when max_bytes is set. We do call copy_bytes in coredump code with
max_bytes set, and for large files, so we might see some benefit from using
c_f_r() on btrfs.
For other filesystems, c_f_r() falls back to do_splice_direct(), the same as
sendfile, which we already call, so there shouldn't be much difference.
Tested with test-copy and systemd-coredump on Linux 4.3 (w/o c_f_r)
and 4.5 (w/ c_f_r).

Also drop ConditionNeedsUpdate=|/etc. Regardless if system is updated

core: look for instance when processing template name
If first attempt to merge units failed and we are trying to do
merge the other way around and at the same time we are working with
template name, then other unit can't possibly be template, because it is
not possible to have template unit running, only instances of the
template. Thus we need to look for already active instance instead.

basic/macros: clang 3.5 doesn't support alloc_size
The attribute was removed in commit c047507 in the clang repository as it
was never properly implemented anyway. Avoid using the attribute with
clang because it generates a ton of annoying warnings.
We called sendfile with 16kb (a.k.a. COPY_BUFFER_SIZE) as the maximum
number of bytes to copy. This seems rather inefficient, especially with
large files. Instead, call sendfile with a "large" maximum.
What "large" max means is a bit tricky: current file offset + max
must fit in loff_t. This means that as we call sendfile more than once,
we have to lower the max size.
With this patch, test-copy calls sendfile twice, e.g.:
sendfile(4, 3, NULL, 9223372036854775807) = 738760
sendfile(4, 3, NULL, 9223372036854037047) = 0
The second call is necessary to determine EOF.
test-copy: add a test shuffling bytes between normal files
I started looking into adding copy_file_range support, and discovered
that we can improve the way we call sendfile:
- sendfile(2) man page is missing an important bit: the number of bytes to
copy cannot be too big (SSIZE_MAX actually), and the description of EINVAL
return code does not mention this either,
- our implementation works but calls sendfile over and over with a small
size, which seems suboptimal.
First add a test which (under strace) can be used to see current behaviour.

include sys/sysmacros.h in more places
Since glibc is moving away from implicitly including sys/sysmacros.h
all the time via sys/types.h, include the header directly in more
