git-gui: added gui.maxrecentrepo to extend the number of remembered repos

The list of recently opened repositories shown when launching git-gui from
outside a repository was hard coded to only show a maximum of 10 items.
This config variable allows the user to override this default.

git-gui: Add gui.displayuntracked option

When git is used to track only a subset of a directory, or
there is no sure way to divide files to ignore from files to track,
git user have to live with large number of untracked files. These files
present in file list, and should always be scrolled through
to handle real changes. Situation can become even worse, then number
of the untracked files grows above the maxfilesdisplayed limit. In the
case, even staged can be hidden by git-gui.

This change introduces new configuration variable gui.displayuntracked,
which, when set to false, instructs git-gui not to show untracked files
in files list. They can be staged from commandline or other tools (like
IDE of file manager), then they become visible. Default value of the
option is true, which is compatible with current behavior.

git-gui: corrected setup of git worktree under cygwin.

Under cygwin the _gitworktree variable needs to contain the Windows
style path string so the output provided by git rev-parse must
be converted from cygwin path style to native.

git-gui: add menu item to launch a bash shell on Windows.

When using git-gui as the primary git application on Windows it can be
awkward obtaining a suitable shell. This commit adds a menu item to the
Repository menu that launches the bash shell provided with the git
installation on Windows.

gitk: Tag display improvements

When a commit has many tags, the tag icons in the graph display can
easily become so wide as to push the commit message off the right-hand
edge of the graph display pane.  This changes the display so that if
there are more than 3 tags or they would take up more than a quarter
of the width of the pane, we instead display a single tag icon with
a legend inside it like "4 tags...".  If the user clicks on the tag
icon, gitk then displays all the tags in the diff display pane.

gitk: Support -G option from the command line

The -G option's usage is exactly analogous to that of -S, so
supporting it is easy.

gitk: Refactor per-line part of getblobdiffline and its support

For later use with data sources other than a pipe, refactor the big
worker part of getblobdiffline to a separate function
parseblobdiffline.  Also refactor its initialization and wrap-up to
separate routines.

gitk: Split out diff part in $commitinfo

So far we just parsed everything after the headers into the "comment"
bit of $commitinfo, including notes and -- if you gave weird options
-- the diff.

Split out the diff, if any, into a separate field.  It's easy to
recognize, since it always starts with /^diff/ and is preceded by an
empty line.

We take care to snip away said empty line.  The display code already
properly spaces the end of the message from the first diff, and
leaving another empty line at the end looks ugly.

gitk: Support showing the gathered inline diffs

The previous commit split the diffs into a separate field.  Now we
actually want to show them.

To that end we use the stored diff, and

- process it once to build a fake "tree diff", i.e., a list of all
  changed files;

- feed it through parseblobdiffline to actually format it into the
  $ctext field, like the existing diff machinery would.

gitk: Recognize -L option

This gives line-log support to gitk, by exploiting the new support for
processing and showing "inline" diffs straight from the git-log
output.

Note that we 'set allknown 0', which is a bit counterintuitive since
this is a "known" option.  But that flag prevents gitk from thinking
it can optimize the view by running rev-list to see the topology; in
the -L case that doesn't work.
