Add back libfec

Remove support for obsolete FreeBSD versions
Reassign maintainer to hamradio@
Cleanups to make sure it compiles cleanly on clang and gcc
Cleanup to (hopefully) allow building on non x86 architectures (untested)

+This library package provides several forward error correction (FEC) decoders
+and accelerated primitives useful in digital signal processing (DSP).
+Except for the Reed-Solomon codecs, these functions take full advantage of
+the MMX, SSE and SSE2 SIMD instruction sets on Intel/AMD IA-32 processors
+and the Altivec/VMX/Velocity Engine SIMD instruction set on the
+G4 and G5 PowerPC. 
+The library includes Viterbi decoders for the following convolutional codes:  
+rate 1/2 k=7 
+rate 1/2 k=9 
+rate 1/6 k=15 ("Cassini")  
+plus two Reed-Solomon encoder-decoders:  
+one optimized for the (255,223) CCSDS standard code 
+a general purpose encoder/decoder for arbitrary RS codes  
+and three low-level 16-bit DSP support routines:  
+signed dot product 
+peak detection 
+sum-of-squares (energy) computation
