This indicates whether the thumbnail (given by G_FILE_ATTRIBUTE_THUMBNAIL_PATH)
is valid — i.e. to represent the file in its current state. If
G_FILE_ATTRIBUTE_THUMBNAIL_IS_VALID is FALSE (for a normal _or_ failed
thumbnail) it means the file has changed since the thumbnail was generated, and
the thumbnail is out of date.
Part of checking thumbnail validity (by the spec) involves parsing
headers out of the thumbnail .png so we include some (small) code to do
that in a separate file. We will likely want to copy this code to gvfs
to do the same for GVfsFile.
Heavily based on a patch from Philip Withnall <philip.withnall@collabora.co.uk>
who suggested the feature and designed the API.
https://bugzilla.gnome.org/show_bug.cgi?id=709898
We now sort the matchers and remove unnecessary duplicates (like
removing standard:type when we already match standard:*), so that we can
do more complex operations on them easily in later commits.
* gio/gfileattribute.c: (_g_file_attribute_value_get_string,
_g_file_attribute_value_set_string): These use
G_FILE_ATTRIBUTE_TYPE_STRING, which is documented as UTF-8, so
document these private functions as using UTF-8.
* gio/gfileinfo.c: (g_file_info_get_attribute_string,
g_file_info_set_attribute_string, and stringv versions):
Document that the strings are UTF-8 because the implementation uses
those private functions, that use UTF-8.
This helps language bindings (such as glibmm) whose API
distinguishes between known and unknown encodings.
This patch and the previous ones fixes the performance issues noted in
Bug 587089 – lookup_attribute() takes too much CPU
It increases performance for querying attributes by ~15% in my tests.

* *.c: chain up unconditionally in finalize() and dispose(). Also
don't dereference these function pointers when calling them since
that has no meaning at all.

* Makefile.am:
* gfileattribute.[ch]:
* gfileattribute-priv.h:
Move GFileAttributeValue to a private header, as
its sort of ugly.

Make set_attribute take a type + a pointer instead
of a GFileAttributeValue.
* gfileinfo.[ch]:
Fix up for above changes.
Add g_file_info_get_attribute_data to get
all info in one call, g_file_info_get_attribute_status
to get the status and g_file_info_get_attribute_as_string.
* gio.symbols:
* glocalfile.c:
* glocalfileinfo.[ch]:
Update for changes

Make _guess_type static.
