DMTCP 1.2.8 released.

DMTCP version 1.2.8 is primarily a bug fix release. It is particularly
recommended to upgrade if you are using DMTCP with the ARM CPU,
or if you will compile DMTCP with a C++11 compiler (e.g. GNU flag -std=c++11).

Important changes include:

• Bug fixes for newer ARM CPUs --- especially addressing cache coherency
  issues of multi-core ARM, and the more aggressive out-of-order
  execution for newer ARM CPUs.
• On restart, gzip zombie processes associated with compressed checkpoint
  images were not always reaped properly. This is now handled correctly.
• Peliminary support for using C++11 compilers to compile DMTCP (but
  not yet intensively tested).
• Minor bug fixes.
