liujunjie ea6ea4313d qstring: Fix qstring_from_substr() not to provoke int overflow ... qstring_from_substr() parameters @start and @end are of type int. blkdebug_parse_filename(), blkverify_parse_filename(), nbd_parse_uri(), and qstring_from_str() pass @end values of type size_t or ptrdiff_t. Values exceeding INT_MAX get truncated, with possibly disastrous results. Such huge substrings seem unlikely, but we found one in a core dump, where "info tlb" executed via QMP's human-monitor-command apparently produced 35 GiB of output. Fix by changing the parameters size_t. Backports commit ad63c549ecd4af4a22a675a815edeb06b0e7bb6e from qemu		2018-08-02 21:21:51 -04:00
