c++11, Config::show_progress option, icu::StringPiece ns

[graehl]

joint_sort.hh: minor c++11 bugfix - change implicit return type to non-const for
--std=c++11 compilation

config.{hh,cc}: add show_progress option (default true, per status quo) - when
we want to see warnings but not progress bars

search_trie.cc, model.cc: use show_progress config

binary_format.cc: warn about all trie types being slow when loading from ARPA

StringPiece.hh: add U_NAMESPACE_QUALIFIER macro for icu::StringPiece if -DHAVE_ICU

Thanks for that. Maybe this fixes clang compilation with C++11.

yeah. i'm using gcc in production but i check clang warnings now and then.
it probably was clang.

thanks for the lm :)

unrelated, i'm curious about two things:

1. if there's a version 6 binary kenlm format, how hard would it be to
   write a converter (perhaps using a temp file)?
2. do you plan on templating State so that the max ngram size can be
   increased without cost? for now we're pretty standardized on 5gram but
   there are a few domains where 7gram is worthwhile ...

This is probably best done over direct e-mail. Anything based on a trie can be recovered exactly so a converter could be written. I'm not ready to guarantee that probing models will be convertible because hashing doesn't have an easy way to get the original n-grams out. As to templates for State, I'm a little worried that the decoder would then resort to dynamic memory allocation which is arguably worse. Moses already dynamically allocates and cdec has its weird string stuff, so this wouldn't be an issue there. Would probably break some existing code though. But I agree it would be good to get rid of the compile-time weirdness. Maybe not a template, just the option to use a fixed-size struct or manually managed variable size.
