Log:
  stable/8: add options KDB and KDB_TRACE to GENERIC kernels
  
  Now that we have code for printing a stack trace on panic using stack(9)
  facility without any debugger backend configured, use this ability
  in GENERIC kernels to slightly increase amount of debugging information
  available in default installations.
  
  This change should not break anything for those who include GENERIC into
  a custom kernel config file and have the above options already enabled.
  They should only get a warning about duplicate options.
  
  This commit should not change behavior of GENERIC kernels for panics and
  traps with respect to core dumping and automatic reset.
  As no debugger backend is configured, enter-to-debugger key combination
  should still be ignored.
  
  With this commit the sizes of GENERIC kernels increase by one to two KB.
  
  This is a direct commit to the branch.
