Bright Pan 2d67fe6565 [Driver/ringbuffer]: Fix put_force bug 
OXape reports: http://www.rt-thread.org/phpBB3/topic3939.html
          driver/ringbuffer: when data length is bigger than space length
          for rb, the read_index in rb is not update.
    When length > space, update the read_index, the bug can be fix, and
          works fine.

Grissiom 4919d29d69 ringbuffer: add put_force and putchar_force API

Grissiom 981d929b56 ringbuffer: fix the ambiguous name 
RT_RINGBUFFER_SIZE could mean "the size of the whole buffer", "the size
of the empty space" or "the size of the data". Moreover, it's never a
micro anymore. Change it to rt_ringbuffer_data_len before it's too late.
Also, RT_RINGBUFFER_EMPTY is changed to rt_ringbuffer_space_len.

Grissiom 952bc0d4ef ringbuffer: format the code to a more symmetric structure 2013-05-08 15:54:30 +08:00
Grissiom 639bd30321 reimplement ringbuffer 
The new implementation use the mirroring method to distinguish full
buffer and the empty buffer. It also support buffers of arbitrary size.
