Fix crash with libgit when it's compiled with GIT_THREADS

Call git_threads_init() before using libgit functions.

The documentation says:

"If libgit2 has been built with GIT_THREADS on, this function must
 be called once before any other library functions.

 If libgit2 has been built without GIT_THREADS support, this function
 is a no-op"

Diveplan with entered and computed waypoints to UI

Recently Robert Helling provided a patch "Distinguish between entered and
calculated waypoints" in an attempt to distinguish between entered and
calculated stops.

This patch is an independent (content wise) extension of the above
patch and is built relative to it which adds new table to display
computed waypoints in plan mode.

Currently table includes only two columns "Comp. Depth" and "Comp.
Duration", which can extended to show further information.

This is only a start to the UI interaction in PLAN mode.
In addition to this there are many TODO things that diveplan feature
demands

TODO:
1. Show more details through "Computed Waypoints" table.
2. Remove tooltip from "Computed Waypoints" table widget.
3. Make contents in "Computed Waypoints" table widget non-editable.
4. Fix error when trying to save dive plan without using cylinder data.
5. Make dive plan editable after saving it.
6. Improvise dive planner graphics window.

Make divelist header corrections Mac specific

The +10 pixels fix was introduced to fix some layout issue on Mac ways
back, but it breaks things on Android. This makes sure this only gets
applied when build for mac.
