syslog: Add header file inclusion to eliminate a warning; mm/iob: private function needs static storage class.

Reformat some code

drivers/bch: BCH character driver bch_ioctl() always returns -ENOTTY for DIOC_GETPRIV command.  It should returns OK if DIOC_GETPRIV command succeeds.

reorganize debug comments
cleanup pending status at boot

implement get_chip_status and use it to detect command errors

Syslog interrrupt buffer:  eliminate a warning about an uninitialized variable; simply some related logic.

Bitbucket Issue 47: Some of last syslog changes needed to be condition on #ifdef CONFIG_SYSLOG_BUFFER in order to be built without syslog buffering enabled.

syslog:  There is yet another place where the output can get split.  That is in syslog_dev_write():  It will break up the stream to insert a CR before the LF.  This can that can be avoid be generating the CR-LF sequence in the buffer and then detecting and ignoring valid CR-LF sequences, rather than expecting syslog_dev_write() to insert the CR in this case.

I don't like the idea that syslog_dev_write() still scans the entire output buffer to expand CR-LF sequence.  This seems really wasteful, especially in this case where we can be sure that the is no CR or LF without a matching LF or CR.  Bu, I think, the existing behavior in syslog_dev_write() must be retained because it is needed in other contexts.

syslog: Avoid flushing syslog_stream buffer, if possible, until lib_vsprintf() completely parses the format.  This assures that the flush will flush the entire output, even data that may potentially follow the linefeed.  And, in that case, it cannot be interleaved with other devug output.  Suggested by Jussi Kivilinna.

add fifo read and write commands
add comments, add a function to set a single byte property
