/****************************************************************************
 * Name: syslog_initialize
 *
 * Description:
 *   One power up, the SYSLOG facility is non-existent or limited to very
 *   low-level output.  This function is called later in the initialization
 *   sequence after full driver support has been initialized.  It installs
 *   the configured SYSLOG drivers and enables full SYSLOGing capability.
 *
 *   This function performs these basic operations:
 *
 *   - Initialize the SYSLOG device
 *   - Call syslog_channel() to begin using that device.
 *
 *   If CONFIG_ARCH_SYSLOG is selected, then the architecture-specifica
 *   logic will provide its own SYSLOG device initialize which must include
 *   as a minimum a call to syslog_channel() to use the device.
 *
 * Input Parameters:
 *  None
 *
 * Returned Value:
 *   Zero (OK) is returned on success; a negated errno value is returned on
 *   any failure.
 *
