Subject: i18n.logToUTF8: convert commit log message to UTF-8

When i18n.commitencoding is set to a non UTF-8 encoding,
commit-tree records the encoding in an extra header after
author/committer headers in the commit object.

An earlier version used trailer but Johannes points out that
there is little risk breaking existing Porcelains with a new
header.

Subject: Teach log family --encoding

Updated commit objects record the encoding used in their
encoding header.  This updates the log family to reencode it
into the encoding specified in i18n.commitencoding (or the
default, which is "utf-8") upon output.

To force a specific encoding that is different, log family takes
command line flag --encoding=<encoding>; giving --encoding=none
entirely disables the reencoding and lets you view log messges
in their original encoding.

Subject: UTF-8: introduce i18n.logoutputencoding.

It is plausible for somebody to want to view the commit log in a
different encoding from i18n.commitencoding -- the project's
policy may be UTF-8 and the user may be using a commit message
hook to run iconv to conform to that policy (and either not have
i18n.commitencoding to default to UTF-8 or have it explicitly
set to UTF-8).  Even then, Latin-1 may be more convenient for
the usual pager and the terminal the user uses.

The new variable i18n.logoutputencoding is used in preference to
i18n.commitencoding to decide what encoding to recode the log
output in when git-log and friends formats the commit log message.

Subject: Rename t3900 test vector file
