[nft PATCH v2 0/3] evaluate: Fix for 'meta hour' ranges spanning date boundaries

[Phil Sutter <phil@nwl.cc>]

Kernel's timezone is UTC, so 'meta hour' returns seconds since UTC start
of day. To mach against this, user space has to convert the RHS value
given in local timezone into UTC. With ranges (e.g. 9:00-17:00),
depending on the local timezone, these may span midnight in UTC (e.g.
23:00-7:00) and thus need to be converted into a proper range again
(e.g. 7:00-23:00, inverted). Since nftables commit 347039f64509e ("src:
add symbol range expression to further compact intervals"), this
conversion was broken.

Changes since v1:
- Apply the parser changes of commit 347039f64509e to JSON parser as
  well (new patches 1 and 2)
- Misc fixes in patch 3

Phil Sutter (3):
  expression: Introduce is_symbol_value_expr() macro
  parser_json: Parse into symbol range expression if possible
  evaluate: Fix for 'meta hour' ranges spanning date boundaries
