change all files to the utf-8 text encoding except *.po

[ndim]

This changes all files in the source tree to the utf-8 text encoding. Currently, the source tree contains a mix of UTF-8 and ISO-8859-1 files, as you can check with file, git, and grep:

[user@host libgphoto2]$ file $(git ls-files) | grep 'UTF'
[user@host libgphoto2]$ file $(git ls-files) | grep 'ISO'

This converts the remaining ISO-8859-x files to UTF-8.

I would not to touch the po files, as we sync them 1:1 from translation project, e.g. they would be overwritten again on next sync. They should be changed on the translationproject side.

Very good. State of affairs at commit 0f5a9b7:

[user@host libgphoto2]$ file $(git ls-files) | grep 'ISO'
libgphoto2_port/po/de.po:    GNU gettext message catalogue, ISO-8859 text
libgphoto2_port/po/eu.po:    GNU gettext message catalogue, ISO-8859 text
[user@host libgphoto2]$ _

Out of curiosity in connection with #733, I have taken a look at the Translation Project's status pages for libgphoto2, libgphoto2_port, and gphoto2, and they all list the German de translations as "external", i.e. someone outside the Translation Project handles the de.po files, i.e. there probably are no external submissions of de.po files which we just copy into our source tree verbatim.

• https://translationproject.org/domain/libgphoto2.html
• https://translationproject.org/domain/libgphoto2_port.html
• https://translationproject.org/domain/gphoto2.html

Judging from the respective de.po files' headers, @msmeissn was the last translator for gphoto2 and libgphoto2, and from the copyright notices for libgphoto2_port as well.

Of these three, only libgphoto2_port/po/de.po is actually still written in ISO-8859-1, so I will change that to UTF-8 shortly.

This will leave libgphoto2_port/po/eu.po (Basque, last translated for 2.5.27) as the only remaining ISO-8859 po file inside the libgphoto2 repo, and three languages (es fi sk Spanish, Finnish, Slovak, last translated for 2.5.9) for the gphoto2 CLI.
