f0367da7d1 core: rename StartLimitInterval= to StartLimitIntervalSec=
We generally follow the rule that for time settings we suffix the setting name
with "Sec" to indicate the default unit if none is specified. The only
exception was the rate limiting interval settings. Fix this, and keep the old
names for compatibility.

Do the same for journald's RateLimitInterval= setting

8580d1f73d journal: rework vacuuming logic
Implement a maximum limit on number of journal files to keep around.
Enforcing a limit is useful on this since our performance when viewing
pays a heavy penalty for each journal file to interleve. This setting is
turned on now by default, and set to 100.

Also, actully implement what 348ced9097
promised: use whatever we find on disk at startup as lower bound on how
much disk space we can use. That commit introduced some provisions to
implement this, but actually never did.

This also adds "journalctl --vacuum-files=" to vacuum files on disk by
their number explicitly.

59f448cf15 tree-wide: never use the off_t unless glibc makes us use it
off_t is a really weird type as it is usually 64bit these days (at least
in sane programs), but could theoretically be 32bit. We don't support
off_t as 32bit builds though, but still constantly deal with safely
converting from off_t to other types and back for no point.

Hence, never use the type anymore. Always use uint64_t instead. This has
various benefits, including that we can expose these values directly as
D-Bus properties, and also that the values parse the same in all cases.

40b71e89ba journald: add support for wall forwarding
This will let journald forward logs as messages sent to all logged in
users (like wall).

Two options are added:
 * ForwardToWall (default yes)
 * MaxLevelWall (default emerg)
'ForwardToWall' is overridable by kernel command line option
'systemd.journald.forward_to_wall'.

This is used to emulate the traditional syslogd behaviour of sending
emergency messages to all logged in users.

ca37242e52 conf-parse: rename config_parse_level() to config_parse_log_level()
"level" is a bit too generic, let's clarify what kind of level we are
referring to here.

5556b5fe41 core: clean up some confusing regarding SI decimal and IEC binary suffixes for sizes
According to Wikipedia it is customary to specify hardware metrics and
transfer speeds to the basis 1000 (SI decimal), while software metrics
and physical volatile memory (RAM) sizes to the basis 1024 (IEC binary).
So far we specified everything in IEC, let's fix that and be more
true to what's otherwise customary. Since we don't want to parse "Mi"
instead of "M" we document each time what the context used is.

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.

26687bf8a9 journal: Add sync timer to journal server
Add option to force journal sync with fsync. Default timeout is 5min.
Interval configured via SyncIntervalSec option at journal.conf. Synced
journal files will be marked as OFFLINE.

Manual sync can be performed via sending SIGUSR1.

d025f1e4dc build-sys: store journald code in a noinst library
The point is to allow the use of journald functions by other binaries.
Before, journald code was split into multiple files (journald-*.[ch]),
but all those files all required functions from journald.c. And
journald.c has its own main(). Now, it is possible to link against
those functions, e.g. from test binaries.

This constitutes a fix for https://bugzilla.redhat.com/show_bug.cgi?id=872638.

The patch does the following:
1. rename journald.h to journald-server.h and move corresponding code
   to journald-server.c.
2. add journald-server.c and other journald-*.c parts to
   libsystemd-journal-internal.
3. remove journald-syslog.c from test_journal_syslog_SOURCES, since
   it is now contained in libsystemd-journal-internal.
There are no code changes, apart from the removal of a few static's,
to allow function calls between files.

6d9082172c journald.conf: remove MinSize= settings
There's no point in making this configurable, so let's drop it in order
to simplify configuration a bit.

fb0951b02e journal: implement time-based rotation/vacuuming
This also enables time-based rotation (but not vacuuming) after 1month,
so that not more one month of journal is lost at a time per vacuuming.
