      fix XcursorTheme loop regression · 6edf1caf
      Tobias Stoeckmann authored 
      

Handle themes with multiple inherit entries. Although the previous
commit keeped track of inherited themes, it only handled multiple theme
entries on the highest level.

This fix unconditionally checks if the next upper level contains a line.
If it does, it processes contained themes (i.e. the current theme had an
inherited entry in its index file).

If the upper level has no more themes, it goes down a level and
processes the next theme there. If no next theme exists, it moves down
another level and so on until it reaches level 0, i.e. the initially
supplied theme.

The lowest level (d = 0) is treated specially because we must not modify
the supplied theme, which could happen when calling _XcursorNextPath.

      Handle more theme loop situations · b47ca985
      Tobias Stoeckmann authored 
      This is a follow up for commit f64a8cc1
resulting from https://bugs.freedesktop.org/show_bug.cgi?id=3603



The current loop detection only works for direct self references but not
for transitive ones. Limiting the inheritance depth fixes this issue as
suggested by Keith Packard.

I avoided the introduction of a recursion function. Instead I modified
XcursorScanTheme to work iterative.

The current recursion code adds the "Inherits=..." line to heap and has
an iteration variable to go through all themes listed in that line per
recursion. This is covered with the newly introduced XcursorInherit
struct with its fields "line" and "theme". Since "theme" points into
"line", only "line" has to be freed eventually.

If a fixed inheritage limit of 32 is reached, the code stops processing
and returns NULL. It also returns NULL if it detects the initial theme
in one of the inheritages to break the loop early on.

Last but not least I removed the printf statement. The only situation in
which libXcursor writes to stdout is when it is explicitly requested.

      Fix undefined behavior · 204b6f13
      Valentin authored 
      Without the casts the bytes accesses get converted to int. but int is
not guaranteed to be 4 bytes large. Even when it is 4 bytes large
`bytes[3] << 24` does not fit because int is signed.

      Use fixed size integer type · 448398a3
      Valentin authored 
      This type is meant to be 4 bytes large as seen in _XcursorReadUInt which
always reads 4 bytes. An unsigned int is often 4 bytes large but this
isnt' guaranteed so it is cleaner to use the exact type we want.

      Support XDG user data dir location · 2263c196
      Cosimo Cecchi authored 
      Nowadays ~/.icons is not used anymore as the preferred location for
custom user icon themes; XDG_DATA_HOME/icons (aka ~/.local/share/icons)
is what toolkits like GTK prefer.

Prepend that location to the default xcursor path, so that cursor
themes installed there can be used by apps and toolkits that use
libXcursor.
