  microoptimization LIFO ddebug_tables list.
  drop doc example comment changes.
  use -v4 in format-patch

  only claim one user flag, dont really need more
  fix patchset grooming err Reported-by: kbuild test robot <lkp@intel.com>
  quoting tweaks in Docs
  rename to lib/dyndbg.c, update docs accordingly
  
changes from v1:
  dont drop trim_prefix yet, its harmless, and better supports old compilers.
  dont move externs to header, despite checkpatch

v1: https://lkml.org/lkml/2019/10/29/989
v2: https://lkml.org/lkml/2019/11/27/547
v3: https://lkml.org/lkml/2019/12/5/735

New Features (review):

accept new query input:
  file inode.c:100-200		# & line-range
  file inode.c:start_*		# & function

add 'u' user flag, allowing user to compose an arbitrary set of
callsites by marking them with 'u', without altering current
print-modifying flags.

extend flags-spec to accept filter-flags before OP and mod-flags,
which select callsites for modification based upon their current
flags.  This lets user activate the set of callsites composed
previously (u+p).

add negating flags to filter on absence of flags, or to negate a modification.
