Free reflists after usage
Free reflists in cgit_print_branches() and in cgit_print_tags() before returning reflist structures to the stack. This fixes following memory leaks seen with "PATH_INFO=/cgit/refs/": ==5710== 1,312 (32 direct, 1,280 indirect) bytes in 1 blocks are definitely lost in loss record 63 of 71 ==5710== at 0x4C2C04B: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==5710== by 0x4C2C2FF: realloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==5710== by 0x46CA9B: xrealloc (wrapper.c:100) ==5710== by 0x40AAA6: cgit_add_ref (shared.c:156) ==5710== by 0x40ABC4: cgit_refs_cb (shared.c:186) ==5710== by 0x44BCBA: do_one_ref (refs.c:527) ==5710== by 0x44D240: do_for_each_ref_in_dir (refs.c:553) ==5710== by 0x44D6BA: do_for_each_ref (refs.c:1298) ==5710== by 0x410FE2: cgit_print_branches (ui-refs.c:191) ==5710== by 0x4111E9: cgit_print_refs (ui-refs.c:244) ==5710== by 0x407C85: refs_fn (cmd.c:105) ==5710== by 0x405DDF: process_request (cgit.c:566) ==5710== ==5710== 6,846 (256 direct, 6,590 indirect) bytes in 1 blocks are definitely lost in loss record 68 of 71 ==5710== at 0x4C2C25E: realloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==5710== by 0x46CA9B: xrealloc (wrapper.c:100) ==5710== by 0x40AAA6: cgit_add_ref (shared.c:156) ==5710== by 0x40ABC4: cgit_refs_cb (shared.c:186) ==5710== by 0x44BCBA: do_one_ref (refs.c:527) ==5710== by 0x44D240: do_for_each_ref_in_dir (refs.c:553) ==5710== by 0x44D6EC: do_for_each_ref (refs.c:1288) ==5710== by 0x4110D5: cgit_print_tags (ui-refs.c:218) ==5710== by 0x4111FD: cgit_print_refs (ui-refs.c:246) ==5710== by 0x407C85: refs_fn (cmd.c:105) ==5710== by 0x405DDF: process_request (cgit.c:566) ==5710== by 0x407490: cache_process (cache.c:322) Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
