[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).

This patch implements the wp_pointer_constraints protocol used for
locking or confining a pointer. It consists of a new global object with
two requests; one for locking the surface to a position, one for
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.

The third arg to strtol() specifies the base to assume for the number.
When 0 is passed, as is currently done in option-parser.c, hexadecimal
and octal numbers are permitted and automatically detected and
converted.
This change is an expansion of f6051cbab8
to cover the remaining strtol() calls in Weston, where the routine is
being used to read fds and pids - which are always expressed in base-10.
It also changes the calls in config-parser, used by
weston_config_section_get_int(), which in turn is being used to read
scales, sizes, times, rates, and delays; these are all expressed in
base-10 numbers only.
The benefit of limiting this to base-10 is to eliminate surprises when
parsing numbers from the command line. Also, by making the code
consistent with other usages of strtol, it may make it possible to
factor out the common code in the future.

strtoul() has a side effect that when given a string representing a

flag an error. IOW, strtoul("-42", &val) sets val to 42. This could
potentially result in unintended surprise behaviors, such as if one were
to inadvertantly set a config param to -1 expecting that to disable it,
but with the result of setting the param to 1 instead.
Catch this by using strtol() and then manually check for the negative
