Add an Accept-Language header which indicates the user's preferred
languages defined by 'LANGUAGE' environment variable if the variable is
not empty.

Example:
  LANGUAGE= -> ""
  LANGUAGE=ko -> "Accept-Language: ko; q=1.000, *; q=0.001"
  LANGUAGE=ko:en -> "Accept-Language: ko; q=1.000, en; q=0.999, *; q=0.001"

This gives git servers a chance to display remote error messages in
the user's preferred language.

Should this also take into account other language-related variables? I'd
think $LC_ALL, $LC_MESSAGES, and $LANG would affect it, too.  Are
colon-separated values a standard in $LANGUAGE? I have never seen them,
but I admit I am not very knowledgeable about localization issues.

Also, we do we need to do more parsing? My $LANG is set to en_US.UTF-8.
The encoding part is presumably uninteresting to the remote server.  I
also wonder if there are support functions in libc or as part of gettext
that can help us get these values.
