po: provide custom make rules for po file management
Historically we have relied on autopoint/gettextize to install a standard po/Makefile.in.in. There is very limited scope for customizing this and it also causes a bunch of extra stuff to be pulled into configure.ac which potentially clashes with gnulib. Writing make rules for po file management is no more difficult than any other rules libvirt has, so stop using autopoint/gettextize.

| Libvirt Message Translation | ||
| =========================== | ||
|
|
||
| Libvirt translatable messages are maintained using the GNU Gettext tools and | ||
| file formats, in combination with the Zanata web service. | ||
|
|
||
| Source repository | ||
| ================= | ||
|
|
||
| The libvirt GIT repository stores the master "libvirt.pot" file and full "po" | ||
| files for translations. The master "libvirt.pot" file can be re-generated using | ||
|
|
||
| make libvirt.pot | ||
|
|
||
| The full po files can have their source locations and msgids updated using | ||
|
|
||
| make update-po | ||
|
|
||
| Normally these updates are only done when either refreshing translations from | ||
| Zanata, or when creating a new release. | ||
|
|
||
| Zanata web service | ||
| ================== | ||
|
|
||
| The translation of libvirt messages has been outsourced to the Fedora | ||
| translation team using the Zanata web service: | ||
|
|
||
| https://fedora.zanata.org/project/view/libvirt | ||
|
|
||
| As such, changes to translations will generally NOT be accepted as patches | ||
| directly to libvirt GIT. Any changes made to "$LANG.mini.po" files in libvirt | ||
| GIT will be overwritten and lost the next time content is imported from Zanata. | ||
|
|
||
| The master "libvirt.pot" file is periodically pushed to Zanata to provide the | ||
| translation team with content changes. New translated text is then periodically | ||
| pulled down from Zanata to update the po files. |
