Desktops and servers tend to have no power sensor, thus on_ac_power returns
255 ("unknown"). Thus, let's take any answer other than 1 ("battery") as
no contraindication to run gc.
If that tool returns "unknown", there's no point in querying other sources
as it already queried them, and is smarter than us (can handle multiple
adapters).

Previously, this would always have exited with 1 on Windows, causing "git
gc --auto" to abort. Fix this by adding support for Windows.

Barring any kernel bugs, if this directory exists and there is
a symlink in there (which will point to the battery object),
that means there is a battery known to the kernel.
No symlink should mean no battery as far as the kernel is concerned.

This hook is evaluated by `git gc --auto` to determine if it is a
good idea to execute a GC at this time, or defer it to some later
date. When working on a laptop its a good idea to avoid GC if you
are on battery power as the extra CPU and disk IO would consume a
decent amount of the charge.
The hook is the standard sample hook from git.git contrib/hooks,
last modified in git.git by 84ed4c5d117d72f02cc918e413b9861a9d2846d7.
I added the GPLv2 header to the script to ensure the license notice
is clear, as it does not match repo's own APLv2 license.
We only update hooks during initial repository creation or on
a repo sync. This way we don't incur huge overheads from the
hook stat operations during "repo status" or even the normal
"repo sync" cases.
