Some tidyups and minor changes to minmax.h.

Patches 1, 2 and 5 have no functional changes.
Patch 3 changes the statically_true() tests in __types_ok() to use the
  local 'unique' variables rather than the caller supplied expressions.
  This will reduce the line length of the preprocessor output.
Patch 4 uses statically_true() for clamp's (lo) < (hi) check.
Patch 6 passes '__auto_type' as the 'fixed type' to reduce the number
  of variants.
Patch 7 removes a level of indirection from __sign_use() and 
  __is_nonneg().

David Laight (7):
  1) Add whitespace around operators and after commas
  2) Update some comments
  3) Reduce the #define expansion of min(), max() and clamp()
  4) Use BUILD_BUG_ON_MSG() for the lo < hi test in clamp()
  5) Move all the clamp() definitions after the min/max() ones.
  6) Simplify the variants of clamp()
  7) Remove some #defines that are only expanded once
