00d1818bb7 man: we need to be more careful with the unit search paths we document
We generally document the suggested paths, not the paths possible in
weird, non-standard setups. We do this in order to not confuse
administrators/users unnecessarily and to push people to install things
into the same directories on all distributions.

We are PID 1 after all, the really basic building block of the OS.
Unlike for an app there's very little benefit in being entirely
relocatable.

910003d022 coredump: use realloc() loop instead of malloc(768M)
I typically run VMs with 1024MiB allocated; systemd is unable to write
coredumps in this scenario at all because the default kernel
configuration will only overcommit 50% of available RAM.

Avoid this failure by using a realloc() loop.

45df1f2c9a build-sys: add --with-debug-shell=PATH
Distributions may have selinux but not sushell or might
need to set a custom debug shell.

Defaults to /sbin/sushell if selinux is enabled, /bin/sh if not.

[zj: Renamed --with-debugshelltty to --with-debug-tty, and
     added a line in output showing DEBUGSHELL and DEBUGTTY.
     I figure that debug shell is pretty useful, and I hope
     the extra line in configure status will draw attention
     to it.]

2a371001f8 Use attribute(unused) in PROTECT_ERRNO
clang emits warnings about unused attribute _saved_errno_, which drown
out other—potentially useful—warnings. gcc documentation is not exactly
verbose about the effects of __attribute__((unused)) on variables, but
let's assume that it works if the unit test passes.

e4d2bfdd73 Add printf attributes in exported headers
gcc (and other compilers) sometimes generate spurious warnings, and
thus users of public headers must be able to disable warnings.

Printf format attributes can be disabled by setting
    #define _sd_printf_attr_
before including the header file.

Also, add similar logic for sentinel attribute:
    #define _sd_sentinel_attr_
before including the header file disables the attribute.

b231b54780 Remove erroneous attribute((malloc)) annotations
According to gcc documentation, returned pointer "cannot alias any
other pointer valid when the function returns" and "the memory has
undefined content". This second part is (hopefully) untrue for all
those functions.

b5edbff035 systemd-python: attach fields to JournalHandler, add SYSLOG_IDENTIFIER
Arbitrary fields can be attached at the level of the handler,
and they'll be sent with all messages from this handler.

This facility is used to attach SYSLOG_IDENTIFIER to all messages,
since otherwise journald attaches SYSLOG_IDENTIFIER=python or
something similar, which is completely useless.

31afa0a44c unit: rework stop pending logic
When a trigger unit wants to know if a stop is queued for it, we should
just check precisely that and do not check whether it is actually
stopped already. This is because we use these checks usually from state
change calls where the state variables are not updated yet.

This change splits unit_pending_inactive() into two calls
unit_inactive_or_pending() and unit_stop_pending(). The former checks
state and pending jobs, the latter only pending jobs.

67fb4482ac always unconditionally create /dev/rtc and use it internally
Partially revert 2b3c81b02f, which
tried to avoid inconsistent rules about when and how to create the
/dev/rtc symlink.

Instead of conditionally or not creating the /dev/rtc link at all,
now always create it with additional and more reliable udev rules.

First try to find the "system rtc" with the hctosys flag, if this
is not found, fall back to create the link for /dev/rtc0.

Our code now never actively searches for the "system rtc" it can
always use /dev/rtc.

c3a170f3d3 systemd: record the timestamps as early as possible
The time for systemd initialization and selinux policy loading
is accounted to the initrd or the kernel, which is wrong.

Instead of:

Startup finished in 5.559s (firmware) + 36ms (loader) + 665ms (kernel) +
975ms (initrd) + 1.410s (userspace) = 8.647s

the more correct output is:

Startup finished in 5.559s (firmware) + 36ms (loader) + 665ms (kernel) +
475ms (initrd) + 1.910s (userspace) = 8.647s

e8a7a31539 nss-myhostname: resolve 'localhost' so that /etc/hosts becomes optional
This makes sure nss-myhostname not only resolves the local host name to
127.0.0.2/::1 but also the host name 'localhost: to 127.0.0.1/::1. This
makes installation of /etc/passwd optional, as it usually only includes
a mapping for 'localhost'.

This change also resolves ::1 to the local hostname (as before), but
also lists 'localhost' as an alias. This means look-ups are now fully
reversible, even though they are 1:n mappings.

Finally, the module will no longer erroneously claim that local IP
addresses which aren't on the loopback device were.

2b3c81b02f do not create /dev/rtc symlink, let systemd search for it if needed
The export of the RTCs hctosys flag is uneccesary, the kernel takes care
of the persistemt clock management itself, without any need for:
  CONFIG_RTC_HCTOSYS=y
  CONFIG_RTC_HCTOSYS_DEVICE="rtc0"

"Chaotic hardware platforms" without native kernel persistent clock
support will find the proper RTC with the logic rtc_open() without
the need for a custom symlink.
