Useful stuff

Scripts and codelets that me prove useful for daily programming:

• Abstraction of thread-local storage (TLS), if the compiler (PGI) or environment (some Unixes) does not support it.
  thread_local_storage.h and thread_local_storage.c
• Codelets to measure TSC and read out the Time-Stamp Counter (TSC) and the core the thread is run on (rdtscp).
