libweston-desktop is an abstraction library for compositors wanting to
support desktop-like shells.
The API is designed from xdg_shell features, as it will eventually be
the recommended shell for modern applications to use.
In the future, adding new shell protocols support will be easier, as
limited to libweston-desktop.
The library versioning is the same as libweston. If one of them break
ABI compatibility, the other will too.
The compositor will only ever see toplevel surfaces (“windows”), with
all the other being internal implementation details.
Thus, popups and associated grabs are handled entirely in
libweston-desktop.
Xwayland special surfaces (override-redirect) are special-cased to a
dedicated layer, as the compositor should not know about them.
All the shell error checking is taken care of too, as well as some
specification rules (e.g. sizes constraint for maximized and fullscreen
surfaces).
All the compositor has to do is define a few callbacks in the interface
struct, and manage toplevel surfaces.

When all outputs are gone and views were created before they
were gone, such views would have no output object assigned and
nothing would assign it later. This makes sure all views are
set as dirty, so they can get an output assigned when an
output gets plugged in, if they didn't have any output assigned.
This change also works when a new output is added even if there already
are outputs in use. A view may be partly off-screen. If the new output
appears at a position where it overlaps an existing view, that view
should get updated.
It is enough to process only the main view_list, because views not on
that list are not shown for the moment and so do not need an immediate
update. Instead, they will get updated later as needed because making an
off-list view to go on-list inherently requires calling
weston_view_geometry_dirty().

This updates the error checking for the strtol() call in xwayland's
create_lockfile to match other cases. C.f. cbc05378 and other recent
patches.
A notable difference here is that the existing error checking was
verifying that exactly 10 digits were being read from the lock file,
but the fact that it's 10 digits is just an implementation detail for
how we're writing it. The pid could be a shorter number of digits, and
would just be space-padded on the left.
This change allows the file to contain any number of digits, but it
can't be blank, all of the digits must be numeric, and the resulting
number must be within the accepted range.

[With hexadecimal color values now handled via their own routine,
re-introduce the negative unsigned numbers fix.]
strtoul() has a side effect that when given a string representing a
negative number, it treats it as a high value hexadecimal. IOW,
strtoul("-42", &val) sets val to 0xffffffd6. This could potentially
result in unintended surprise behaviors.
Catch this by using strtol() and then manually check for the negative
value. This logic is modelled after Wayland's strtouint().
Note that this change unfortunately reduces the range of parseable
numbers from [0,UINT_MAX] to [0,INT_MAX]. The current users of
weston_config_section_get_uint() are anticipating numbers far smaller
than either of these limits, so the change is believed to have no impact
in practice.
Also add a test case for negative numbers that catches this error
condition.

Previously weston_config_section_get_uint was serving dual purpose for
parsing both unsigned decimal integer values (ids, counts, seconds,
etc.) and hexadecimal values (colors), by relying on strtoul's
auto-detection mechanism.
However, this usage is unable to catch certain kinds of error
conditions, such as specifying a negative number where an unsigned
should be used. And for colors in particular, it would misparse hex
values if the leading 0x was omitted. E.g. "background-color=99999999"
would render a near-black background (effectively 0x05f5e0ff) instead of
medium grey, and "background-color=ffffffff" would be treated as an
error rather than white. "background-color=0x01234567",
"background-color=01234567", and "background-color=1234567" each
resulted in the value being parsed as hexadecimal, octal, and decimal
respectively, resulting in colors 0x01234567, 0x00053977, and 0x0012d687
being displayed.
This new routine forces hexadecimal to be used in all cases when parsing
color values, so "0x01234567" and "01234567" result in the same color
value, "99999999" is grey, and "ffffffff" is white. It also requires
exactly 8 or 10 digits (other lengths likely indicate typos), or the
value "0" (black).

confining the pointer to a given region.
In this patch, only the locking part is fully implemented as in
specified in the protocol, while confinement is only implemented for
when the union of the passed region and the input region of the confined
surface is a single rectangle.
Note that the pointer constraints protocol is still unstable and as
such has the unstable protocol naming conventions applied.
