Merge branch 'pr/1792'
src/daemon/common.[ch]: Reimplement strjoin().
This new implementation truncates fields rather than aborting when there
is more space in the output buffer. Since strjoin() is mostly used to
fill plugin and type instances, which are otherwise usually filled with
sstrncpy(), i.e. also truncate the string rather than erroring out.
The unit test has also been rewritten to test the new functionality.
The new functions have been formatted with clang-format.
Fixes: #1792

hugepages plugin: Don't use pathconf(_PC_NAME_MAX).
Since we allocate the buffer on the stack, this doesn't make sense:
Best case, the returned value is the same as the PATH_MAX define. Worst
case, the returned value is larger and we create a stack overflow.

Use struct initializers to initialize the array like so:

vl.values = values;
vl.values_len = STATIC_ARRAY_SIZE (values);

curl_json plugin: Skip unexpected non-map values.
Assume, for example, the config `Key "*/foo"`. This config expects JSON
in the form:
{
"bar": {
"foo": 1337
}
}
If the available JSON is instead:
{
"error_code": 0,
"bar": {
"foo": 1337
}
}
the code will take a look at the zero associated with "error_code" and
determine that a map (with key "foo") is expected instead. Previously
the code would continue, eventually calling `cj_get_type()` which
expects that `key->type` is a valid pointer, resulting in a segmentation
fault.
This patch does three things to ensure that this segmentation fault does
not happen again:
1. `cj_get_type()` checks its argument to make sure it is valid before
dereferencing any pointers.
2. In case a non-map is found when a map is expected, the code will
return instead of limping on.
3. After calling `cj_cb_inc_array_index()`, which may update the key,
make sure that it actually did and that key is valid now.
Fixes: #1896
