[PATCH] gnu: services: Add git-service.

Right now, this service does not work (vm does not build) when I try to build the vm
with "./pre-inst-env guix system vm ../testvm-git.scm", where ../testvm-git is a file I will append in the 2nd follow-up message.

+@subsubsection Version Control
+
+The @code{(gnu services version-control)} module provides the following services:
+
+@subsubheading Git daemon service
+
+@deffn {Scheme Procedure} git-daemon-service [#:config (git-daemon-configuration)]
+
+Return a service that runs @command{git daemon}, a simple TCP server to
+expose repositiories over the Git protocol for annoymous access.
+
+The optional @var{config} argument should be a
+@code{<git-daemon-configuration>} object, by default it allows read-only
+access to exported@footnote{By creating the magic file
+"git-daemon-export-ok" in the repository directory.} repositories under
+@file{/srv/git}.
+
+@end deffn
+
+@deftp {Data Type} git-daemon-configuration
+Data type representing the configuration of git-demon.
+
+@table @asis
+@item @code{package} (default: @var{git})
+Package object of the Git distributed version control system.
+
+@item @code{export-all?} (default: @var{#f})
+Whether to allow access for all Git repositories, even if they do not
+have the @file{git-daemon-export-ok} file.
+
+@item @code{base-path} (default: @file{/srv/git})
+Whether to remap all the path requests as relative to the given path.
+If you run git daemon with @var{(base-path "/srv/git")} on example.com,
+then if you later try to pull @code{git://example.com/hello.git}, git
+daemon will interpret the path as @code{/srv/git/hello.git}.
+
+@item @code{user-path} (default: @var{#f})
+Whether to allow @code{~user} notation to be used in requests.  When
+specified with empty string, requests to @code{git://host/~alice/foo} is
+taken as a request to access @code{foo} repository in the home directory
+of user @code{alice}.  If @var{(user-path "path")} is specified, the
+same request is taken as a request to access @code{path/foo} repository
+in the home directory of user @code{alice}.
+
+@item @code{listen} (default: @var{'()})
+Whether to listen on specific IP addresses or hostnames, defaults to
+all.
+
+@item @code{port} (default: @var{#f})
+Whether to listen on an alternative port, which defaults to 9418.
+
+@item @code{whitelist} (default: @var{'()})
+If not empty, only allow access to this list of directories.
+
+@item @code{extra-options} (default: @var{'()})
+Extra options will be passed to @code{git daemon}, please run
+@command{man git-daemon} for more information.
