Added comedi_get_buffer_read_offset(), comedi_get_buffer_write_offset(),
comedi_get_buffer_read_count(), and comedi_get_buffer_write_count().
comedi_get_buffer_read_offset() is the same as
comedi_get_buffer_offset(), which has now been documented as deprecated,
but is currently still declared in "comedilib.h" by default. It gets
the read position within the buffer as an offset from the start of the
buffer (modulo the buffer size).
comedi_get_buffer_write_offset() gets the write position within the
buffer as an offset from the start of the buffer (modulo the buffer
size).
comedi_get_buffer_read_count() gets the number of bytes read from the
buffer, modulo UINT_MAX+1.
comedi_get_buffer_write_count() gets the number of bytes written to the
buffer, modulo UINT_MAX+1.
