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

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.
