"tjAlloc()" uses "malloc()" which takes a "size_t" number of bytes (an
unsigned integer).

However,"tjAlloc()" itself takes the number of bytes as a signed integer.
So the width * height * tjPixelSize[pixelfmt] may overflow and become a
negative integer.

Fix by checking it and change to use malloc directly.

Cli doesn't depend on littlefs and posix, clean them.  And make the
other code better.

[HUST CSE]除了开头的haas_mux_i2c_init函数返回了ret，其它的函数均没有返回值，修改增加了返回值

Before this patch, only the first waiting task will be listed in debug
command.
Now add the feature to list all waiting tasks for
sem/mutex/buf_queue/queue.

In the solution rfid_demo, the documentation about the RFID is
not clear enough. So directly using a better documentation instead
of writing it.
