[Xen-devel] [PATCH v2 00/11] xentoollog, libvchan: Minor improvements

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

The point of this series is to make an API promise about what ENOENT
means from libxenvchan_client_init, to make it easier to build async
code on top of this (eg, libxl).

There is a lot of internal tidying, but also a necessary prefix is a
change to xentoollog to make it OK to pass NULL for a logger.  This
allows elimination of all the duplicates of the default logger creation.
(Otherwise we'd have to have added yet another dupe to libvchan.)

 +  01/11  tools/libs/toollog: Provide a default logger
 +  02/11  tools/libs/toollog: Use the default logger
 +  03/11  tools/libs/*: Rely on the default logger
  a 04/11  tools/libvchan: Initialise xs_transaction_t to XBT_NULL, not NULL
  a 05/11  tools/xenstore: Document that xs_close(0) is OK.
  a 06/11  tools/libvchan: init_xs_srv: Simplify error handling (1)
  a 07/11  tools/libvchan: init_xs_srv: Simplify error handling (2)
  a 08/11  tools/libvchan: init_xs_srv: Turn xs retry from goto into for (;;)
  a 09/11  tools/libvchan: Add xentoollog to direct dependencies
  a 10/11  tools/libvchan: libxenvchan_*_init: Promise an errno
    11/11  tools/libvchan: libxenvchan_client_init: use ENOENT for no server

  +  new patch in v2
