Lennart Poettering a1e58e8ee1 tree-wide: use coccinelle to patch a lot of code to use mfree()
This replaces this:

        free(p);
        p = NULL;

by this:

        p = mfree(p);

Change generated using coccinelle. Semantic patch is added to the
sources.

Michael Chapman 403ed0e5c9 bus-util: support details in CheckAuthorization calls
Extra details for an action can be supplied when calling polkit's
CheckAuthorization method. Details are a list of key/value string pairs.
Custom policy can use these details when making authorization decisions.

Lennart Poettering 25300b5a1f util: make machine_name_is_valid() a macro and move it to hostname-util.h
As it turns out machine_name_is_valid() does the exact same thing as
hostname_is_valid() these days, as it just invoked that and checked the
name length was < 64. However, hostname_is_valid() checks the length
against HOST_NAME_MAX anyway (which is 64 on Linux), hence any
additional check is redundant.

We hence replace machine_name_is_valid() by a macro that simply maps it
to hostname_is_valid() but sets the allow_trailing_dot parameter to
false. We also move this this call to hostname-util.h, to the same place
as the hostname_is_valid() declaration.

Vincent Batts cca3a6b118 import: don't create sparse tar archives
Sparse archives are good for files like utmp/wtmp and journals, but it
is still expenseive in having to read the files twice to archive them.
Additionally there is a supportability issue as GNU sparse archives are
not supported by many archive libraries and tooling.

Zbigniew Jędrzejewski-Szmek 8fb4944358 hostname-util: add relax parameter to hostname_is_valid
Tests are modified to check behaviour with relax and without relax.
New tests are added for hostname_cleanup().
Tests are moved a new file (test-hostname-util) because there's
now a bunch of them.

New parameter is not used anywhere, except in tests, so there should
be no observable change.

David Herrmann 97b11eedff tree-wide: introduce mfree()
Pretty trivial helper which wraps free() but returns NULL, so we can
simplify this:
        free(foobar);
        foobar = NULL;
to this:
        foobar = mfree(foobar);

Daniel Mack 45d9a30414 tree-wide: do not use _cleanup_free_ on const pointers
free() cannot be used with const pointers. However, our _cleanup_free_
handler features cast logic that hides that qualifier, so we don't get a
warning.

Lennart Poettering 03976f7b4a sd-bus: introduce new sd_bus_flush_close_unref() call
sd_bus_flush_close_unref() is a call that simply combines sd_bus_flush()
(which writes all unwritten messages out) + sd_bus_close() (which
terminates the connection, releasing all unread messages) +
sd_bus_unref() (which frees the connection).

The combination of this call is used pretty frequently in systemd tools
right before exiting, and should also be relevant for most external
clients, and is hence useful to cover in a call of its own.

Previously the combination of the three calls was already done in the
_cleanup_bus_close_unref_ macro, but this was only available internally.

Also see #327

Pavel Odvody 4764a54439 import/pull: fix pulling by image digest
When pulling by image digest the identifiers that
were produced by parsing image digest were later
overwritten by code parsing image tag.
This resulted in invalid identifiers being used
when contacting the remote endpoint, resulting in 404.

Lennart Poettering 72c0a2c255 everywhere: port everything to sigprocmask_many() and friends
This ports a lot of manual code over to sigprocmask_many() and friends.

Also, we now consistly check for sigprocmask() failures with
assert_se(), since the call cannot realistically fail unless there's a
programming error.

Also encloses a few sd_event_add_signal() calls with (void) when we
ignore the return values for it knowingly.

Lennart Poettering 14bcf25c8b util: when creating temporary file names, allow including extra id string in it
This adds a "char *extra" parameter to tempfn_xxxxxx(), tempfn_random(),
tempfn_ranomd_child(). If non-NULL this string is included in the middle
of the newly created file name. This is useful for being able to
distuingish the kind of temporary file when we see one.

This also adds tests for the three call.

For now, we don't make use of this at all, but port all users over.

Lennart Poettering 9030ca462b sd-bus: allow passing NULL as bus parameter to sd_bus_send()

make use of this.

Lennart Poettering 190700621f sd-bus: drop bus parameter from message callback prototype
This should simplify the prototype a bit. The bus parameter is redundant

Lennart Poettering 527b7a421f util: rework cunescape(), improve error handling
Change cunescape() to return a normal error code, so that we can
distuingish OOM errors from parse errors.

This also adds a flags parameter to control whether "relaxed" or normal
parsing shall be done. If set no parse failures are generated, and the
only reason why cunescape() can fail is OOM.

Alban Crequy f85ef957e6 util: add rename_noreplace
renameat2() exists since Linux 3.15 but btrfs support for the flag
RENAME_NOREPLACE was added later.

This patch implements a fallback when renameat2() returns EINVAL.
EINVAL is the error returned when the filesystem does not support one of
the flags.

Lennart Poettering 26166c88e0 importd: automatically grow /var/lib/machines/ loopback filesystem during downloads
If /var/lib/machines is mounted as btrfs loopback file system in
/var/lib/machines.raw with this change we automatically grow the file
system as it fills up. After each 10M we write to it during imports, we
check the free disk space, and if the fill level grows beyond 66% we
increase the size of the file system to 3x the fill level (thus lowering
it to 33%).
