Regression of speed in lzip-1.25-rc1

[wrotycz]

Regression of speed in lzip-1.25-rc1   Trying the new version (1.25-rc1) I 
noticed significant speed regression in compression of ~ 12% relative to 
previous version.   ~~~  $ time lzip-1.24 -kf mozilla   real    0m43.845s  user 
   0m43.475s  sys     0m0.289s   $ time lzip-1.25-rc1 -kf mozilla   real    
0m49.074s  user    0m48.720s  sys     0m0.295s  ~~~   --   Similarily 
plzip/lzlib decomression is ~12% slower than that of c/lzip. This is old thing 
though.    More details here:  pastebin.mozilla.org
