Adds a safe strtol helper function, modeled loosely after Wayland
scanner's strtouint. This encapsulates the various quirks of strtol
behavior, and streamlines the interface to just handling base-10 numbers
with a simple true/false error indicator and a uint32_t return by
reference.
Test cases are loosely derived from an earlier patch by Imran Zaman.

Make the error checking consistent with other strtol() calls.
Note that since strtol(nptr, &endptr) sets endptr == nptr if there were
no digits, this catches the case where the string was blank, so there's
no need to test *value != '\0'.

[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).

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.

In weston and the weston clients and tests using option-parser.c, the
options are all things that can be expected to be specified in base 10:
widths, heights, counts, scales, font sizes, ports, ttys, connectors,
etc. The subsurfaces client uses two modes, limited to values 0 and 1
only. The zuc testsuite has a --random parameter for specifying a seed,
which is the only option where using hexadecimal or octal numbers might
conceivably happen.

Check errno, which is set of over/underflow, out of range, etc. Also
check for empty strings (the usages covered in this patch already also
cover the case where there are non-digits present). Set errno to 0
before making the strto*l call in case of pre-existing errors
(i.e. ENOTTY when running under the testsuite).
This follows the error checking style used in Wayland
(c.f. wayland-client.c and scanner.c).
In tests, also check errno, and add testcases for parsing '0'.

We have the Weston command line option '--no-config' which is meant to
prevent loading weston.ini at all. It works for Weston itself, but it
does not work for any clients that also want to read weston.ini.
To fix that, introduce a new environment variable WESTON_CONFIG_FILE.
Weston will set it to the absolute path of the config file it loads.
Clients will load the config file pointed to by WESTON_CONFIG_FILE. If
the environment variable is set but empty, no config file will be
loaded. If the variable is unset, things fall back to the default
"weston.ini".
Note, that Weston will only set WESTON_CONFIG_FILE, it never reads it.
The ability to specify a custom config file to load will be another patch.
All programs that loaded "weston.ini" are modified to honour
WESTON_CONFIG_FILE.
