1. Disable SYSLOG_DEFAULT by default …

   Because the implementation is problematic.
   See apache#14662 for the discussion.
   Also, make it depend on EXPERIMENTAL to discourage it.
   
   Instead, enable SYSLOG_CONSOLE for a bit more cases.
   
   An alternative would be to introduce/extend some serialization
   mechanism (eg. enter_critical_section, which is currently used by
   the serial driver to interact with interrupts) to cover up_putc
   users including SYSLOG_DEFAULT. While it works, it doesn't sound
   attractive to me to introduce this kind of complexity to up_putc,
   which is supposed to be a very low-level machinary used early in
   the boot. Also, the implementation of such serialization can be
   complex because how up_putc works is basically device-specific and
   how it corresponds to other devices on the system (eg. uarts) isn't
   obvious to the upper layers.
