services: xorg: Allow users to specify a list of modules. 

* gnu/services/xorg.scm (%default-xorg-fonts): New variable.
(xorg-configuration-file): Add #:modules and #:fonts.  Rewrite to return
a 'computed-file' that honors MODULES and FONTS.
(xorg-wrapper): Pass #:modules to 'xorg-configuration-file'.
(xorg-start-command): Add #:fonts.  Pass #:fonts and #:modules to
'xorg-configuration-file'.
* doc/guix.texi (X Window): Adjust documentation of 'xorg-start-command'
and 'xorg-configuration-file'.

@deffn {Scheme Procedure} xorg-start-command [#:guile] @
[#:configuration-file #f] [#:xorg-server @var{xorg-server}]
Return a derivation that builds a @var{guile} script to start the X server
from @var{xorg-server}. @var{configuration-file} is the server configuration
file or a derivation that builds it; when omitted, the result of
@code{xorg-configuration-file} is used.
[#:modules %default-xorg-modules] @
[#:fonts %default-xorg-fonts] @
[#:configuration-file (xorg-configuration-file @dots{})] @
[#:xorg-server @var{xorg-server}]
Return a @code{startx} script in which @var{modules}, a list of X module
packages, and @var{fonts}, a list of X font directories, are available. See
@code{xorg-wrapper} for more details on the arguments. The result should be
used in place of @code{startx}.
Usually the X server is started by a login manager.

Return a configuration file for the Xorg server containing search paths for
all the common drivers.
@var{modules} must be a list of @dfn{module packages} loaded by the Xorg
server---e.g., @code{xf86-video-vesa}, @code{xf86-input-keyboard}, and so on.
@var{fonts} must be a list of font directories to add to the server's
@dfn{font path}.
@var{drivers} must be either the empty list, in which case Xorg chooses a
graphics driver automatically, or a list of driver names that will be tried in
this order---e.g., @code{(\"modesetting\" \"vesa\")}.

Likewise, when @var{resolutions} is the empty list, Xorg chooses an
appropriate screen resolution; otherwise, it must be a list of
resolutions---e.g., @code{((1024 768) (640 480))}.
Last, @var{extra-config} is a list of strings or objects appended to the
@code{text-file*} argument list. It is used to pass extra text to be added
verbatim to the configuration file.
