[PATCH] config.c: Remove unused git_config_global() function

Commit 8f323c00 (drop support for GIT_CONFIG_NOGLOBAL, 15-03-2011)
removed the git_config_global() function, among other things, since
it is no longer required. Unfortunately, this function has since
been unintentionally restored; I suspect by merge commit 25b86e45
(Merge branch 'jk/maint-config-alias-fix' into next, 25-05-2011).

Hi Junio,

A few days ago, when the next branch was @ d10669c, I noticed that
"make sparse" on next was complaining thus:

    config.c:828:5: warning: symbol 'git_config_global' was not \
        declared. Should it be static?

However, I remembered that this function had recently been removed, so
I took a quick look ...

ATB,
Ramsay Jones
