Explicitly set MHD_OPTION_CONNECTION_MEMORY_LIMIT to a larger value,
when setting up microhttpd, to give more memory per HTTP(S) connection.
This way systemd-journal-remote can now prevent microhttpd from failing
in creating response headers with messages like "Not enough memory for
write", especially when lots of HTTPS requests arrive. That's precisely
because MHD_OPTION_CONNECTION_MEMORY_LIMIT in libmicrohttpd defaults to
32768, which is in practice insufficient in this case.

Currently, we dispatch NOTIFY messages in a tight loop. Regardless how
much data is incoming, we always dispatch everything that is queued.
This, however, completely breaks priority event-handling of sd-event.
When dispatching one NOTIFY event, another completely different event
might fire, or might be queued by the NOTIFY handling. However, this
event will not get dispatched until all other further NOTIFY messages are
handled. Those might even arrive _after_ the other event fired, and as
such completely break priority ordering of sd-event (which several code
paths rely on).
Break this by never dispatching multiple messages. Just return after each
message that was read and let sd-event handle everything else.
(The patch looks scarier that it is. It basically just drops the for(;;)
loop and re-indents the loop-content.)
Tests for the functions defined in src/basic/parse-util.c. Reorder them
to match the order in which the functions are defined in the source
file. Adjusted the list of include files to remove the ones no longer
needed in test-util.c.
Tested that `make check` still passes as expected. Also checked the
number of lines removed from test-util.c matches the expected, as an
additional verification that no tests were dropped or duplicated in the
move.
Document support for commas as a separator and possibility of specifying
ranges of CPU indices.
Tested by regenerating the manpages locally and reading them on man.
Tested CPUAffinity ranges on both a service unit and in system.conf and
confirmed they work as expected (by inspecting /proc/PID/status, for the
main pid of the service and for pid 1). Also mixed ranges with both
spaces, commas, trailing commas and spaces.
Added new tests to increase coverage of ranges and prevent regressions.
Tested CPUAffinity settings on both a service unit and in system.conf
and confirmed they work as expected.
Added a new test to confirm that trailing commas and spaces work and to
prevent any regressions in that area.
When coldplugging the unit state, make sure to follow the same basic
logic for all unit types: always verify whether the control PID is still
a waitable process before proceeding.
Since 5fd9b2c546 passing a pid of 0 to
pid_is_unwaited() and pid_is_live() is considered as a request on the
current process, similar how the other calls in process-util.c handle a
PID of 0. This broke service.c, which passes a 0 PID and expects it to
be considered an unwaited process.
This fix make sure we can boot again.
