* Silence coverity CHECKED_RETURN on added.f load
The existing code behaved alright since added.f is optional.
However, by testing for success we can both silence the warning
and prevent a useless initialization of NULL/0 to added_f and
added_f_length.
* Silence coverity CHECKED_RETURN on added6.f load
ipv6 variant of previous commit.
* Silence coverity CHECKED_RETURN writing benc strs
saveStringFunc() gets the target string by calling tr_variantGetStr().
It previously didn't check to see if this function succeeded because
saveStringFunc() isn't reached without the type already being known.
However, checking the return value costs nothing and makes Coverity happy.
* Silence coverity CHECKED_RETURN on ut metadata
Like earlier few Coverity commits in this PR, we're handling optional
values by declaring stack locals set to the default (e.g. -1) and then
trying to read the variant.
Unlike the earlier commits, there is a two-part step to thise read:
checking for the metadata, then checking for the individual fields.
The earlier fixes' aproach -- e.g. initializing to -1 only if the reads
failed -- would involve new nested conditionals. I find the new complexity
to outweigh the benefit of removing the dead store, so in this case I'm
casting the return value to `(void)` to tell Coverity to shush.
* Silence coverity CHECKED_RETURN on scrape
Check the return value of tr_variantGetInt() when showing
seeder and leecher counts in transmission-show.
* Silence CHECKED_RETURN on rpc recently-active
When building a list of removed torrent IDs from variants, confirm that
we can read the IDs from the variants before adding them to the list.
I don't _think_ this would have failed before, but Coverity's right that
it's reasonable to add a safeguard here.
* fix: better fix to serializing benc strings
