Regarding:
commit 2b6783191da7 ("dynamic_debug: add trim_prefix() to provide source-root relative paths")
commit a73619a845d5 ("kbuild: use -fmacro-prefix-map to make __FILE__ a relative path")
2nd commit broke dynamic-debug's "file $fullpath" query form, but
nobody noticed because 1st commit trimmed prefixes from control-file
output, so the click-copy-pasting of fullpaths into new queries had
ceased; that query form became unused.
Removing the function is cleanest, but it could be useful in
old-compiler corner cases, where __FILE__ still has /full/path,
and it safely does nothing otherwize.
So instead, quietly deprecate "file /full/path" query form, by
removing all /full/paths examples in the docs. I skipped adding a
back-compat note.

1. Add a user-flag [u] which works like original [pfmlt] flags, but
has no effect on callsite behavior; it allows marking of arbitrary
sets of callsites.
2. Add [PFMLTU] flags, which negate their counterparts; P===!p etc.
And in ddebug_read_flags():
current code does: [pfmltu_] -> flags
copy it to: [PFMLTU_] -> mask
also disallow both of a pair: ie no 'pP', no true & false.
3. Add filtering ops into ddebug_change(), right after all the
callsite-property selections are complete. These test the callsite's
current flagstate before applying modflags.
Why ?
The new user flag facilitates batching of changes. By marking
individual callsites with 'u', user can compose an arbitrary set of
changes, then activate them together by selecting on 'u':
#> echo 'file foo.c +u; file bar.c +u' > control
#> echo 'u+p' > control
The user flag isn't strictly needed, but with it you can avoid using
[fmlt] flags for marking, which would alter logging when enabled.

Extend flags modifications to allow [PFMLTU] inverted flags.
This allows control-queries like:
#> Q () { echo file inode.c $* > control } # to type less
#> Q -P # same as +p
#> Q +U # same as -u
#> Q u-P # same as u+p
This allows flags in a callsite to be simultaneously set and cleared,
while still starting with the current flagstate (with +- ops).
Generally, you chose -p or +p 1st, then set or clear flags
accordingly.
