fix: gcc warnings in libtransmission/ and utils/ (#843) * fix: __attribute__(__printf__) warnings * fix: implicit fallthrough warning * fixup! fix: implicit fallthrough warning * fix: disable warnings for 3rd party code Since we want to leave upstream code as-is * fixup! fix: disable warnings for 3rd party code * fixup! fix: disable warnings for 3rd party code * silence spurious alignment warning Xrefs Discussion: https://stackoverflow.com/a/35554349 Macro inspiration: https://pagure.io/SSSD/sssd/blob/90ac46f71068d131391492360a8553bdd005b5a7/f/src/util/util_safealign.h#_35 * fixup! fix: disable warnings for 3rd party code * fixup! fix: implicit fallthrough warning * make uncrustify happy * remove uncrustify-test.sh that's probably off-topic for this PR * fixup! fix: __attribute__(__printf__) warnings * Update libtransmission/CMakeLists.txt Co-Authored-By: ckerr <ckerr@github.com> * fixup! silence spurious alignment warning * use -w for DISABLE_WARNINGS in Clang * refactor: fix libtransmission deprecation warnings * fix: pthread_create's start_routine's return value This was defined as `void` on non-Windows but should have been `void*` * chore: uncrustify * fix: add DISABLE_WARNINGS option for SunPro Studio * fix "unused in lambda capture" warnings by clang++ * fix 'increases required alignment' warning Caused from storing int16_t's in a char array. * fix net.c 'increases required alignment' warning The code passes in a `struct sockaddr_storage*` which is a padded struct large enough for the necessary alignment. Unfortunately it was recast as a `struct sockaddr*` which has less padding and a smaller alignment. The warning occrred because of these differing alignments. * make building quieter so warnings are more visible * fixup! fix 'increases required alignment' warning * Fix -Wcast-function-type warnings in GTK+ app code https://gitlab.gnome.org/GNOME/gnome-terminal/issues/96 talks about both the issue and its solution. GCC 8's -Wcast-function-type, enabled by -Wextra, is problematic in glib applications because it's idiomatic there to recast function signatures, e.g. `g_slist_free(list, (GFunc)g_free, NULL);`. Disabling the warning with pragmas causes "unrecognized pragma" warnings on clang and older versions of gcc, and disabling the warning could miss actual bugs. GCC defines `void (*)(void)` as a special case that matches anything so we can silence warnings by double-casting through GCallback. In the previous example, the warning is silenced by changing the code to read `g_slist_free(list, (GFunc)(GCallback)g_free, NULL);`). * fixup! fix "unused in lambda capture" warnings by clang++ * fixup! fix "unused in lambda capture" warnings by clang++ * fix two more libtransmission compiler warnings * fix: in watchdir, use TR_ENABLE_ASSERTS not NDEBUG
