Specifying the path for mime-info files.

Hey there. :)

I noticed  that libgnomevfs library  1.0.5 looks for mime-info  files in
two  locations: GNOME_VFS_DATADIR (a  C  preprocessor  symbol that  gets
hardcoded into the library) and ~/.gnome/mime-files.

I've been seeing  how to make GNOME  play nicely with GNU stow  so it is
possible to install each of  GNOME's packages into a different directory
and use  environment variables  and similar mechanism  to make  it work.
I'm creating a document with instructions on how to do this.

Unfortunately, as libgnomevfs has the system directory for the mime-info
files hardcoded,  it is impossible  for the user  to specify it.   In my
situation,  I  would  like  libgnomevfs  to  look  for  these  files  in
/usr/local/share/mime-info rather  that in the datadir  for the location
on which the gnome-vfs package was installed.

Attached   is   a  trivially   simple   patch   that  fixes   this   and
causes  gnome-vfs  to  look  in  the  directory  specified  through  the
GNOME_VFS_DATADIR  environment variable  (this  environment variable  is
checked at run time rather than at compile time).

The  only other  viable  solution  involves forcing  the  admin to  keep
the  mime-info files  in gnome-vfs'  prefix  updated with  links to  all
the  files in  the  GNOME directory.   I'd rather  go  for specifing  an
environment variable, specially as a  similar mechanism has already been
implemented  for  similar  GNOME  packages (through  variables  such  as
GNOMEDIR,  GNOME_PATH,  GNOME_LIBCONFIG_PATH, GNOME_GNORBA_PATH  and  so
on).

Notice that this makes it possible  for the user to override the default
system directory for  mime-info files, which shouldn't  matter (but then
again I am not familiar with gnome-vfs ins and outs).

Please let  me know if I  can expect my  changes to get included  in the
next official  release so I will  know what to write  in my instructions
document.

Thanks. :)
