Simon Ser 75f476c01e surface: allow locking pending state in commit handler
We were bumping the pending sequence number after emitting the
commit event, so commit handlers were seeing inconsistent state
where current.seq == pending.seq. This prevents commit handlers
from immediately locking the pending state.

Fix this by bumping the pending sequence number before firing the
commit event.

Simon Ser 4b2ef3dff9 surface: accept commits with buffer size not divisible by scale
There are still many situations where the buffer scale is not
divisible by scale. The fix will require a tad more work, so
let's just log the client error for now and continue handling
the surface commit as usual.

Simon Ser 9e58301df7 surface: allow placing subsurfaces below parent
Prior to this commit, subsurfaces could only be placed above their
parent. Any place_{above,below} request involving the parent would
fail with a protocol error.

However the Wayland protocol allows using the parent surface in the
place_{above,below} requests, and allows subsurfaces to be placed
below their parent.

Weston's implementation adds a dummy wl_list node in the subsurface
list. However this is potentially dangerous: iterating the list
requires making sure the dummy wl_list node is checked for, otherwise
memory corruption will happen.

Instead, split the list in two: one for subsurfaces above the parent,
the other for subsurfaces below.

Tested with wleird's subsurfaces demo client.

Simon Ser e0258f4506 surface: introduce cached states
Cached states allow a surface commit to be delayed. They are useful for:

Kenny Levinsen ebecc5404b surface: Make send_enter store entered outputs

bound.

how cursors use this interface.

Simon Ser ca45f4490c Remove all wayland-server.h includes
The documentation for wayland-server.h says:

> header and as such only defines the library PI, excluding the deprecated API

Replacing wayland-server.h with wayland-server-core.h allows us to drop the
WL_HIDE_DEPRECATED declaration.

Las afa2e399aa Fix implicit conversion of floats to ints in calls to pixman_region32_contains_point
I do not think the conversion is specifically defined, but on my system and SirCmpwn's
the floats are rounded instead of floored, which is incorrect in this case, since
for a range from 0 to 256, any value greater or equal to 0 and less than 256 is valid.
I.e. [0;256[, or 0 <= x < 256, but if x is e.g. -0.1, then it will be rounded to 0, which
is invalid. The correct behavior would be to floor to -1.
