Alexandros Frantzis 2180858592 tests: Add checks for pointer motion and button event timestamps
Enhance the existing pointer motion and button event tests to
additionally verify the event timestamps. This requires updating the
weston-test protocol to support passing motion and button event
timestamps.

Emilio Pozuelo Monfort 4f3cad7828 compositor: damage pending subsurfaces when committing them
When a client changes the subsurfaces state, we need to damage
them so the result is visible. We do that by flagging the surfaces
when the state changes and causing damage when committing the
state. This prevents normal repaints from considering these changes
until a commit has happened, and allows the client to atomically
schedule several changes.

This fixes the subsurface_z_order test, which is now marked as expected
to succeed.

Daniel Stone 4938f93f57 tests: Remove buffer-count
buffer-count was introduced in line with a Mesa change which forced
an earlier block on frame events to try to enforce double-buffering
where available.

The Mesa change has since been reverted (Mesa commit 9ca6711faa), as
this had unpleasant interactions with buffer_age in particular, so this
test is no longer valid.

Additionally, it only worked on backends which initialised EGL (not
headless-backend, where tests generally run), which can be flaky due to
initialisation races. Not only that, but on the DRM backend, we can
legitimately enter triple-buffering due to promoting the surface to a
hardware plane, skipping GPU composition.

In light of all this, just remove the test.

Bryce Harrington d0716f4af5 Re-apply "config-parser: Catch negative numbers assigned to unsigned config values"
[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.

Bryce Harrington e776f2a4d9 config-parser: Add weston_config_section_get_color
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).
