- anagram: Fix two off-by-ones, the heap size, and the result
- rijndael_dec: Reset result checksum at job start
- huff_enc: Reset mutable global variables at job start

Also move run_all_dis.sh up a directory in preperation for
further changes.

- anagram, audiobeam: Reset heap in _init() function
- g723_enc: Don't use static local variables
- huff_dec: Reset all global state in _init() function

No other changes.

- Use consistent approach to prevent computations from being
  optimized out in the DIS benchmarks
- Don't print results in the DIS benchmarks
- Fix a memory corruption in TACLe's "epic" benchmark reflect1()
- Fix return codes for all benchmarks
- Rename run_baseline.sh to run_bench.sh in preperation for this
  being the main benchmarking script

There was previously a huge amount of shared code that had to be
copied back and forth. This should reduce the maintenance burden
by containing all future changes to a single file.

New unified library is fully backwards-compatible but also
introduces and the easy-to-use `for_each_job` macro which
replaces the specific `for(...) START_LOOP ... STOP_LOOP`
format requirement and is generally much harder to abuse.

New unified library also automatically cleans up its shared memory
and semaphores, so this commit also removes the separate
`cleanupSemaphores` binary.

I also found a precursor of `extra.h` written by Sims in
`litmusStuff.h`. This code is only interesting for historical
purposes, so it is also removed in this commit.

This commit also adds debug options to all the Makefiles and
silences rm's complaints about non-existent files in make clean.

Also remove some unused code from the cleanupSemaphores utility
