The current config parser, parses the ini file and pulls out the values
specified by the struct config_section passed to parse_config_file() and
then throw the rest away. This means that every place we want to get
info out of the ini file, we have to parse the whole thing again. It's not
a big overhead, but it's also not a convenient API.
This patch adds a parser that parses the ini file to a data structure and
puts that in weston_compositor->config along with API to query comfig
keys from the data structure. The old parser is still available, but
we'll transition to the new approach over the next few commits.
This set of changes adds support for searching for a given config file
in the directories listed in $XDG_CONFIG_DIRS if it wasn't found in
$XDG_CONFIG_HOME or ~/.config. This allows packages to install custom
config files in /etc/xdg/weston, for example, thus allowing them to
avoid dealing with home directories.
To avoid a TOCTOU race the config file is actually open()ed during the
search. Its file descriptor is returned and stored in the compositor
for later use when performing subsequent config file parses.

Eventually we will want more functionality in the shared library and we
will rename it at that point. Perhaps we'll name it libnih, but for now
let's stick with libconfig-parser.
Rename CONFIG_KEY_BOOL to CONFIG_KEY_BOOLEAN, just like
CONFIG_KEY_INTEGER is not CONFIG_KEY_INT, for consistency.
Document the types expected for the void* and name the enum in the
header, so it is clear what config_key::type means.

Add a helper function, that constructs a path to a config file from
XDG_CONFIG_HOME environment variable, by the rules of
http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html
Make desktop-shell find its config file from XDG_CONFIG_HOME. This
allows to have a personal config file without continuously fighting with
git about wayland-desktop-shell.ini.
