- Added signal declaration string 

 module. The difference is that now the target directory is recreated only
 if it does not exist (previously: always recreated which caused only the
 last copy_files entry in hdllib.cfg to have effect).

Key hdl_lib_excludes now only applies to synthesis to avoid Modelsim compile error on library clause in e.g. tech_ddr_stratixiv.vhd.

Added 100 q) and 100 r). Key hdl_lib_excludes now only applies to synthesis to avoid Modelsim compile error on library clause in e.g. tech_ddr_stratixiv.vhd.

- Removed unused strings
- Added some function comments
- Added function that reads board peripherlas from separate file. 
 

Updated all IP related files to match Quartus 15.0 which uses libraries with _150 in their names instead of -141.

For now use /tools/quartus/check_ipx_content only for quartus 15.0, because the dir path for 11.1sp2 is 11.1 and thus does not fit.

Define toolset unb2 to use Quartus v15.0. Upgrade all Arria10 IP. Use check_ipx_content in set_quartus. Created /15.0 with the simulation models.

 hidden file now: '.run_rbf_temp_options_file').

This fix accommodates the behavior of both versions

Check if locale en_US (en_US.iso88591) is present.  If not, it will throw error with /home/software/Altera/11.1sp2/quartus/adm/qenv.sh

"svn info" produces French string that are not properly parsed by quartus_generic.sh

Only used for SITE=USN now, but feel free to test and use it for other SITE.

Move technolgyNames from command line to hdltool.cfg. Use modelsim_search_libraries from hdltool.cfg. Made rmtree in copy_files() more safe. Introduced toolset level in build dir.
