[ccan] [PATCH 0/4] Replace TCON() with TCON_WRAP()

[David Gibson]

ccan/tcon has two basic ways to be used.  With TCON() which adds a
type canary to a user's existing structure, or with TCON_WRAP(), which
wraps a user's structure creating a new structure with the canaries.

TCON() is older and has several modules already using it.
Unfortunately, it uses flexible-array members which aren't allowed in
the middle of structures, except as a gcc extension.  That means with
a "normal" compiler TCON() invocations can only appear at the end of a
structure.  More importantly it also means a structure including them
can never be embedded in another structure except at the end.

In short, using TCON() is either non-portable, or badly violates
principle of least surprise.  So, this series removes use of it from
all existing ccan modules.

David Gibson (4):
  tlist: Use TCON_WRAP instead of TCON
  jset: Use TCON_WRAP instead of TCON
  jmap: Use TCON_WRAP instead of TCON
  objset: Use TCON_WRAP instead of TCON
