[PATCH v5 00/10] Incremental po/git.pot update and new l10n workflow

[Jiang Xin <worldhello.net@gmail.com>]

From: Jiang Xin <zhiyou.jx@alibaba-inc.com>

Changes since v4:

1. Patch 1/10: use sort function instead of passing option "--sort-by-file".
2. Patch 3/10: when finding source files, ignore ".build" directory.
3. New patch 5/10: remove duplicate and unwanted files in FOUND_SOURCE_FILES
4. Patch 7/10: no "--sort-by-file" option $(MSGCAT_FLAGS) for msgcat.
5. Patch 9/10: no "--sort-by-file" option $(MSGCAT_FLAGS) for msgcat,
               and remove unused "core-pot" target.

    -    Makefile: sort "po/git.pot" by file location
    +    Makefile: sort source files before feeding to xgettext
     
         We will feed xgettext with more C source files and in different order
         in subsequent commit. To generate a stable "po/git.pot" regardless of
    -    the number and order of input source files, we pass the option
    -    "--sort-by-file" to xgettext program.
    +    the number and order of input source files, we sort the c, perl, and
    +    shell source files in groups before feeding them to xgettext.
    +
    +    Ævar suggested that we should not pass the option "--sort-by-file" to
    +    xgettext to sort the translatable strings, as it will mix the three
    +    groups of source files (c, perl and shell) in the file "po/git.pot",
    +    and change the order of translatable strings in the same line of a file.
     
         With this update, the newly generated "po/git.pot" will have the same
         entries while in a different order.
    @@ Commit message
         We won't checkin the newly generated "po/git.pot", because we will
         remove it from tree in a later commit.
