3ffd4af220 util-lib: split out fd-related operations into fd-util.[ch]
There are more than enough to deserve their own .c file, hence move them
over.

07630cea1f util-lib: split our string related calls from util.[ch] into its own file string-util.[ch]
There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.

This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.

Also touches a few unrelated include files.

fea72cc033 macro: introduce new PID_TO_PTR macros and make use of them
This adds a new PID_TO_PTR() macro, plus PTR_TO_PID() and makes use of
it wherever we maintain processes in a hash table. Previously we
sometimes used LONG_TO_PTR() and other times ULONG_TO_PTR() for that,
hence let's make this more explicit and clean up things.

but don't do anything else. We still want to kill as much as
possible.

2eec67acbb remove unused includes
This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.

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.

d5099efc47 hashmap: introduce hash_ops to make struct Hashmap smaller
It is redundant to store 'hash' and 'compare' function pointers in
struct Hashmap separately. The functions always comprise a pair.
Store a single pointer to struct hash_ops instead.

systemd keeps hundreds of hashmaps, so this saves a little bit of
memory.

3e09eb5c83 core: fix invalid free() in killall()
static int killall(....) in ./src/core/killall.c tries to get "s"
initialized by calling get_process_comm(...) which calls
read_one_line_file(...) which if it fails will mean it is left
uninitialized.
It is then used in argument to strna(s) call where it is
dereferenced(!), in addition to nothing else initializing it before
the scope it is in finishes.

ccd06097c7 Use format patterns for usec_t, pid_t, nsec_t, usec_t
It is nicer to predefine patterns using configure time check instead of
using casts everywhere.

Since we do not need to use any flags, include "%" in the format instead
of excluding it like PRI* macros.

aaf7eb81be shutdown: correctly wait for processes we killed in the killall spree
Previously we simply counted how many processes we killed and expected
as many waitpid() calls to succeed. That however is incorrect to do.

As we might kill processes that are not our immediate children, and as
there might be left-over processes in the waitpid() queue from earlier
the we might get more ore less waitpid() events that we expect.

Hence: keep precise track of the processes we kill, remove the ones we
get waitpid() for, and after each time we get SIGCHLD check if all
others still exist. We use getpgid() to check if a PID still exists.

This should fix issues with journald not setting journal files offline
correctly on shutdown, because we'd too quickly proceed from SIGTERM to
SIGKILL because some left-over process was in our waitpid() queue.

cee530bb23 switch-root: don't wait for processes
When we transition from the initrd to the main system, don't reap
processes, so that they can be handled normally after deserialization.
