**Describe the bug you encountered:** I used rustdesk to connect to my home computer today and played DianFeng Tank from QQ Game. The mouse can move, but the game's collimator...

tb_buffer_memncpyp会错误地改变目标缓冲区的大小

``` tb_buffer_t b; tb_buffer_init(&b); tb_buffer_memncpy(&b, (tb_byte_t const*)"abcde", 6); // data[0-5] tb_trace_i("%s", tb_buffer_data(&b)); printf("size: %ld\n", tb_buffer_size(&b)); printf("maxn: %ld\n", tb_buffer_maxn(&b)); printf("data[%ld]=%d\n", tb_buffer_size(&b), *((char*)tb_buffer_data(&b)+tb_buffer_size(&b))); printf("data[%ld]=%d\n", tb_buffer_size(&b)+1, *((char*)tb_buffer_data(&b)+tb_buffer_size(&b)+1)); printf("data[%ld]=%d\n", tb_buffer_size(&b)+2, *((char*)tb_buffer_data(&b)+tb_buffer_size(&b)+2)); tb_buffer_memncpyp(&b, 1, "XY",...

xmake f -h的输出与实际不符

xmake f xmake xmake package 之后，扩展模块xml与coroutine处在未开启状态，然而 xmake f -h 的输出却显示开启  如果这俩选项会被 --small=y 覆盖，建议在帮助信息中给出提示。

tb_vsnprintf当第二个参数即缓冲区大小为0时，行为与标准库中的vsnprintf不一致

### 描述问题 tbox目前的实现是这样的 ``` tb_long_t tb_vsnprintf(tb_char_t* s, tb_size_t n, tb_char_t const* fmt, tb_va_list_t args) { // check if (!n || !s || !fmt) return 0; ``` 即当n等于0时，直接返回0。 ### 期待的结果 然而标准库里的vsnprintf的行为是这样的：...
