[xml] xmlLoadCatalogs behaviour

[Igor Zlatkovic <igor stud fh-frankfurt de>]

Hi all,

the KDE people cried about xmlLoadCatalogs not accepting the colon as a
directory separator in its parameter. They were right, because the newly
introduced behaviour which supports URI notation breaks the old habits and
all projects which relied on that.

I have reverted the behaviour of xmlLoadCatalogs to the old way. This keeps
compatibility, but means no URI notation and no usage on Windows (where
every path specification contains a colon).

I would introduce a new function, xmlLoadCatalogList(const char* paths),
which has a full URI support and separates directories by a space
exclusively.

Is that okay?

Ciao
Igor
