Begin adding an autotools implementation
squash! Begin adding an autotools implementation

Update the README file to admit that I'm using autotools.
Make no-simd build again
Detect X86/X86_64 at configure time
Integrate the rest of the tests into the "make check", except for haskell
Make 'make distcheck' pass.
Add --enable and --disable arguments for things controlled by OTTERY_NO_* macros
Restore uncrustify and doxygen and reset-gcov
Add commented-out coverage target to remind me to put that back.
Detect ghc and python; include ghc test in 'make check'
Add m4 to .gitignore
Add the warnings back in AM_CFLAGS. May need more work for other platforms
Distribute more documentation and cfg files
Narrow the uncrustifiles
stub pkgconfig file
Comments and light reorganization for autotools files.
Fix a warning with OTTERY_NO_INIT_CHECK
Fix test/test_deep when run with OTTERY_NO_CLEAR_AFTER_YIELD
Merge branch 'topic/autotools'
