Dropped LFSR_ATTR() prefix magic

Browse Source 
Before:

  LFSR_ATTR(RM(SUBMASK(REG)), 0, BUF("hi", 2))

Now:

  LFSR_ATTR(
      LFSR_TAG_RM | LFSR_TAG_SUBMASK | LFSR_TAG_REG, 0,
      LFSR_DATA_BUF("hi", 2))

Yes, it's more verbose now.

But there were a couple reasons for dropping the idea:

- The implicit prefixing is a bit magical, and not really all that
  common in C code. It would likely confuse new users on first read.

- The implicitly prefixing macros did not play will with macro expansion
  rules.

  In particular, because the nested not-yet-prefixed macros aren't
  really macros, they aren't expanded as a part of argument prescan.
  This led to surprising compile-time errors, and prevented recursive
  attr-lists (which may be useful for shrubs).

- Implicit prefixes is not very C-like, and in particular it gets in the
  way of sed/grep operations on source files.

- RM(SUBMASK(REG)) for combining tags is (IMO) ugly, compared to
  LFSR_TAG_RM | LFSR_TAG_SUBMASK | LFSR_TAG_REG, even if the latter
  requires more typing.

- Sometimes you need runtime-dependent TAG/DATA values, which implicit
  prefixing gets in the way of. The LFSR_TAG_TAG(tag)/
  LFSR_DATA_DATA(tag) backdoors worked around this, but they are even
  more magical, and added noise to a not-actually-all-that-uncommon use
  case.

And it's really not _that_ much extra effort to write out the prefixes
everywhere.

qadte came in quite handy again for refactoring the tests without
completely losing my sanity.
