build, i18n: improve Intl build, add "--with-intl" The two main goals of this change are: - To make it easier to build the Intl option using ICU (particularly, using a newer ICU than v8/Chromium's version) - To enable a much smaller ICU build with only English support The goal here is to get node.js binaries built this way by default so that the Intl API can be used. Additional data can be added at execution time (see Readme and wiki) More details are at https://github.com/joyent/node/pull/7719 In particular, this change adds the "--with-intl=" configure option to provide more ways of building "Intl": - "full-icu" picks up an ICU from deps/icu - "small-icu" is similar, but builds only English - "system-icu" uses pkg-config to find an installed ICU - "none" does nothing (no Intl) For Windows builds, the "full-icu" or "small-icu" options are added to vcbuild.bat. Note that the existing "--with-icu-path" option is not removed from configure, but may not be used alongside the new option. Wiki changes have already been made on https://github.com/joyent/node/wiki/Installation and a new page created at https://github.com/joyent/node/wiki/Intl (marked as provisional until this change lands.) Summary of changes: * README.md : doc updates * .gitignore : added "deps/icu" as this is the location where ICU is unpacked to. * Makefile : added the tools/icu/* files to cpplint, but excluded a problematic file. * configure : added the "--with-intl" option mentioned above. Calculate at config time the list of ICU source files to use and data packaging options. * node.gyp : add the new files src/node_i18n.cc/.h as well as ICU linkage. * src/node.cc : add call into node::i18n::InitializeICUDirectory(icu_data_dir) as well as new --icu-data-dir option and NODE_ICU_DATA env variable to configure ICU data loading. This loading is only relevant in the "small" configuration. * src/node_i18n.cc : new source file for the above Initialize.. function, to setup ICU as needed. * tools/icu : new directory with some tools needed for this build. * tools/icu/icu-generic.gyp : new .gyp file that builds ICU in some new ways, both on unix/mac and windows. * tools/icu/icu-system.gyp : new .gyp file to build node against a pkg-config detected ICU. * tools/icu/icu_small.json : new config file for the "English-only" small build. * tools/icu/icutrim.py : new tool for trimming down ICU data. Reads the above .json file. * tools/icu/iculslocs.cc : new tool for repairing ICU data manifests after trim operation. * tools/icu/no-op.cc : dummy file to force .gyp into using a C++ linker. * vcbuild.bat : added small-icu and full-icu options, to call into configure. * Fixed toolset dependencies, see https://github.com/joyent/node/pull/7719#issuecomment-54641687 Note that because of a bug in gyp {CC,CXX}_host must also be set. Otherwise gcc/g++ will be used by default for part of the build. Reviewed-by: Trevor Norris <trev.norris@gmail.com> Reviewed-by: Fedor Indutny <fedor@indutny.com>
