36afca67b6 udevadm hwdb: discard extra leading whitespaces in hwdb
Currently a property in the form of
  FOO=bar
is stored as " FOO=bar", i.e. the property name contains a leading space.
That's quite hard to spot.

This patch discards all extra whitespaces but the first one which is required
by libudev's hwdb_add_property.

[zj: modify the check a bit]

fddf1a3189 mount: deal with inotify queue overflow
Overflow is very unlikely, since we are watching a privileged directory,
but could be triggered if thousands of mounts are suddently executed.

affc3d8343 mount: check options as well as fstype for network mounts
When creating a new mount unit after an event on /proc/self/mountinfo,
check the mount options as well as the fstype to determine if this is a
remote mount that requires network access.

a6d305f91d mount: add remote-fs dependencies if needed after change
This is an attempt to add it the remote-fs dependencies to a mount unit
if the options change, like when the utab options are picked up after
mountinfo has already been processed.  It just adds the remote-fs
dependencies, leaving the local-fs ones in place.

With this change I always get mount units with proper remote-fs
dependencies when mounted with the _netdev option.

befb6d5494 mount: monitor for utab changes with inotify
Parsing the mount table with libmount races against the mount command,
which will handle the actual mounting before updating utab.  This means
the poll event on /proc/self/mountinfo can kick of a reparse in systemd
before the utab information is available.

This change adds in an additional event source using inotify to watch
for changes to utab.  It only watches for IN_MOVED_TO events, matching
libmount behavior of always overwriting this file using rename(2).

This does add a second pass through the mount table parsing when utab is
updated.

8d3ae2bd4c mount: use libmount to enumerate /proc/self/mountinfo
This lets libmount add in user options from /run/mount/utab, like
_netdev which is needed to get proper ordering against remote-fs.target

56f64d9576 treewide: use log_*_errno whenever %m is in the format string
If the format string contains %m, clearly errno must have a meaningful
value, so we might as well use log_*_errno to have ERRNO= logged.

Using:
find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/'

Plus some whitespace, linewrap, and indent adjustments.

e80733be33 Revert "systemctl: append default suffix only if none present"
This reverts a chunk out of commit 5e03c6e3b5
which was trying to pass NULL to the the '.service' default. Anyway,
it seems better to be explicit.

5e03c6e3b5 systemctl: append default suffix only if none present
Simplify unit_name_mangle() and unit_name_mangle_with_suffix() to
always behave the same, and only append a suffix if there is no
type suffix. If a user says 'isolate blah.device' it is better to
return an error that the type cannot be isolated, than to try to
isolate blah.device.target.

5567fafbc9 hostnamectl: Exit with zero on success
In show_all_names(), bus_map_all_properties() returns 1 on success which is
then used as the return code of show_all_names() and eventually main(). Exit
with zero in main() on all nonnegative results to guard against similar errors.

0a1beeb642 treewide: auto-convert the simple cases to log_*_errno()
As a followup to 086891e5c1 "log: add an "error" parameter to all
low-level logging calls and intrdouce log_error_errno() as log calls
that take error numbers", use sed to convert the simple cases to use
the new macros:

find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/'

Multi-line log_*() invocations are not covered.
And we also should add log_unit_*_errno().
