[0/4] Support C++ pointer-to-member types

  Hello,

This patch is in response to a feature enhancement request filed at
https://sourceware.org/bugzilla/show_bug.cgi?id=30260.

The first patch is a preparatory patch that improves how type names are
pretty-printed, especially derived types like pointers and arrays.

The second patch really is the patch that adds the support for C++
pointer-to-member types.

The last two patches bump the ABIXML format version and libabigail
SONAME due to the changes made to the ABIXML format and to the ABI of
libabigail itself.

Dodji Seketeli (4):
  Improve type naming
  Bug 30260 - Support pointer-to-member type
  Bump abixml version to 2.3
  Bump LIBABIGAIL_SO_CURRENT version to 4
