Various fixes:

Browse source 
- Fix an uninitialized variable
 
  - Fix compile bug to bootconfig userspace tool (in tools directory)
 
  - Suppress some error messages of bootconfig userspace tool
 
  - Remove unneded CONFIG_LIBXBC from bootconfig
 
  - Allocate bootconfig xbc_nodes dynamically.
    To ease complaints about taking up static memory at boot up
 
  - Use of parse_args() to parse bootconfig instead of strstr() usage
    Prevents issues of double quotes containing the interested string
 
  - Fix missing ring_buffer_nest_end() on synthetic event error path
 
  - Return zero not -EINVAL on soft disabled synthetic event
    (soft disabling must be the same as hard disabling, which returns zero)
 
  - Consolidate synthetic event code (remove duplicate code)
