RFR: 1236: Add jcheck option to check for large binary files [v6]

[Guoxiong Li]

> Hi all,
>
> This patch adds the large binary file check to the jcheck.
>
> The corresponding configuration is like the following code. Each key/value in the `[checks "binary"]` is a mapper. The `key` means the file pattern and the `value` means the limited file size. For example, `.*\.bin=200B` means the file which ends with `.bin` should not exceed 200 Bytes.

>
> [checks]
> error = binary

> [checks "binary"]
> .*.bin=200B
> .*.o=1k

> The limited file size can use one of these several units:  b(Byte), kb(KiloByte), mb(MegaByte), gb(GigaByte). The units is case insensitive, which means the `Kb`, `kB` and `KB` are equals to `kb(KiloByte)`. If the unit is not provided, it defauts to `b(Byte)`. And these is no a unit called `bit`.
>
> The corresponding test cases are added.
