git-gui: fix git-gui crash due to uninitialized variable

Recently, a clone initiated via git gui on Windows crashed on me due to
an "unknown variable cdone". It turns out that there is a code path
where this variable is used uninitialized.

git-gui: Use PWD if it exists on Mac OS X

The current working directory is set to / when git-gui is invoked
using the Git Gui.app bundle on Mac OS X. This means that if it is
launched from a directory which contains a repository then git-gui
won't automatically find it unless the repository happens to be
located in /.

The PWD environment variable is however preserved if the bundle is
invoked using open(1). If git-gui would check for PWD then a user
could for example type open -a 'Git Gui' on a command line in order to
launch the program and it would automatically find the repository.

Teach git-gui to use the PWD environment variable on Mac OS X.

git-gui: open console when using --trace on windows

When starting a gui program on windows stdout, stderr and stdin are not
connected to the cmd console. As a workaround tk has a console window.
Lets open this when the --trace commandline option has been given.
This is helpful for debugging.

git-gui: preserve commit messages in utf-8

The commit message buffer is automatically preserved to a local file
but this uses the system encoding which may fail to properly encode
unicode text. Forcing this file to use utf-8 preserves the message
correctly.

git-gui: de.po: consistently add untranslated hook names within braces

The user might not really know what hook is
actually meant if it's translated. To avoid such
a confusion we should consistently write it untranslated
within braces after.

push: start warning upcoming default change for push.default

In preparation for flipping the default to the "simple" mode from
the "matching" mode that is the historical default, start warning
users when they rely on unconfigured "git push" to default to the
"matching" mode.

Also, advertise for 'simple' where 'current' and 'upstream' are advised.

difftool: Eliminate global variables

Organize the script so that it has a single main() function which
calls out to dir_diff() and file_diff() functions. This eliminates
"dir-diff"-specific variables that do not need to be calculated when
performing a regular file-diff.

difftool: Use symlinks when diffing against the worktree

Teach difftool's --dir-diff mode to use symlinks to represent
files from the working copy, and make it the default behavior
for the non-Windows platforms.

Using symlinks is simpler and safer since we do not need to
worry about copying files back into the worktree.
The old behavior is still available as --no-symlinks.

difftool: Handle finding mergetools/ in a path with spaces

Use the original File::Find implementation from bf73fc2 (difftool:
print list of valid tools with '--tool-help', 2012-03-29) so that we
properly handle mergetools/ being located in a path containing
spaces.

One small difference is that we avoid using a global variable by
passing a reference to the list of tools.
