[ccan] [PATCH 0/5] new ccan/list functionality

[Eric Wong]

These are mainly for replacing some custom linked-list implementations
in the mainline Ruby VM; but should be useful for other projects.

Patches 1 and 2 are reviewed by David.

Patches 3-5 are implemented based on David's comments in
<20141006235924.GA12838 at voom.redhat.com>
for my original list_for_each_rev_safe patch.

Eric Wong (5):
      list: list_add_after and list_add_before functions
      list: list_swap to exchange elements
      list: new list_for_each{,_safe}_off_dir_ macros
      list: add list_for_each_rev_off macro
      list: add list_for_each_rev_safe{,_off} macros
