The change eliminates the fixed size buffers in gen_suppression and show_used_suppressions. This is achieved by changing the return type from VG_TDICT_CALL(tool_get_extra_suppression_info and VG_TDICT_CALL(tool_print_extra_suppression_use from Bool to SizeT. A return value of 0 indicates that nothing (except the terminating '\0' which is always inserted) was written to the buffer. This corresponds to the previous False return value. A return value which is equal to the buffer size (that was passed in as function argument) indicates that the buffer was not large enough. The caller then resizes the buffer and retries. Otherwise, the buffer was large enough. Regtested with a resize value of 1. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@14606
