9cebb234b1 busctl: add a --json= output mode 
A new switch "-j" or "--json=" is added which transforms dbus
marshalling into json. This is extremely useful in combination with
tools such as "jq" to process bus calls further.

a5d8835c78 mempool: only enable mempool use when linked to libsystemd-shared.so 
Mempool use is enabled or disabled based on the mempool_use_allowed symbol that
is linked in.

Should fix assert crashes in external programs caused by #9792.
Replaces #10286.

v2:
- use two different source files instead of a gcc constructor

7c48ea0280 Move use_pool() to mempool.c and rename to mempool_enabled() 
The only user is in hashmap.c, but it's a mempool thing.

c42c981924 meson: remove old comment

2614d83aa0 tests: pass halt_on_error=1 to UBSan 
By default, UBSan neither crashes nor exits with a non-zero exit code
when undefined behavior has been detected. This is problematic because
it makes it much harder to catch issues like https://github.com/systemd/systemd/issues/10346,
 https://github.com/systemd/systemd/issues/10347, and https://github.com/systemd/systemd/issues/10333.
In fact, those issue were found just because I decided to grep
the test log, which isn't something that I normally do :-)

As it turns out, the only way to make UBSan signal that something is wrong that works more or less
reliably everywhere is to pass halt_on_error=1 (though, it's probably worth noting that it's currently
not set for PID1 in order not to trigger kernel panics).

See https://reviews.llvm.org/D35085#804183 and https://chromium.googlesource.com/chromium/src/testing/libfuzzer/+/HEAD/reference.md

c09edc79ab meson: c++ is required for the fuzzer builds 
The configuration would fail with an error about cpp being an unknown language
anyway, but it's nicer to fail early and explicitly.

9b0ca01903 meson: rename cpp_cmd to cxx_cmd 
cpp is a really bad alias for c++ because it's also the name of the
preprocessor. Let's rename the variable.

5f00c5684f capability: introduce CAP_TO_MASK_CORRECTED() macro replacing CAP_TO_MASK() 
linux/capability.h's CAP_TO_MASK potentially shifts a signed int "1"
(i.e. 32bit wide) left by 31 which means it becomes negative. That's
just weird, and ubsan complains about it. Let's introduce our own macro
CAP_TO_MASK_CORRECTED which doesn't fall into this trap, and make use of
it.

Fixes: #10347

just us linking against an existing JSON library.
