* Prevent libcurl from inadvertently being initialized twice.
* Dynamically load libcurl only when required.
* Reduce the number of worker threads when loading footprint libraries to
prevent issues with the GitHub plugin.
This simplifies the pad DRC significantly and fixes a bug when two pads
are close to each other in a right angle, when the edge distances are
below the clearance, but the corner distance is actually above the
clearance:

<Chris> Pad DRC has handling for trapezoid pads and handling for square
pads. This patch looks relatively low-risk to me, as square is a subset
of trapezoid and the handling for trapezoid pads is not specific to that
pad type.
* Uncouple SCH_COMPONENT::GetRef() from SCH_SHEET_PATH and use SCH_SHEET
instead.
* Uncouple SCH_COMPONENT::GetUnitSelection() from SCH_SHEET_PATH and use
SCH_SHEET instead.
* Fix all calls to GetRef() and GetUnitSelection() to pass a pointer to the
appropriate SCH_SHEET object instead of an SCH_SHEET_PATH object.
* Replace the wxListCtrl with a wxTreeListCtrl, allowing expandable categories
in a future change.
* Clean up the code to make HOTKEY_LIST_CTRL function a bit better on its own.
* Migrate the hotkey dialog to TransferData{To,From}Window, use matching
TransferData{To,From}Control methods on HOTKEY_LIST_CTRL so it is easy to
embed.
* Enables USE_WX_GRAPHICS_CONTEXT for OSX by default. This shouldn¡¯t be a
major change because it seems to get used on OSX behind the scenes anyway.
As a side effect, this might improve behavior with anti-aliasing because
KiCad shifts drawing by (0.5, 0.5) into the middle of the virtual pixels so
things may be less blurry. It will still build without enabling
USE_WX_GRAPHICS_CONTEXT, but the optimizations obviously won¡¯t be used.
* The optimizations currently only are effective when USE_WX_GRAPHICS_CONTEXT
is enabled and OSX. They might be also good for other platforms using
USE_WX_GRAPHICS_CONTEXT because it aggregates some drawing primitives using
paths wxGraphicsContext provides.
* It adds some #ifdefs for disabling the wxGraphicsContext stuff when
USE_WX_GRAPHICS_CONTEXT isn¡¯t enabled. If you hate #ifdefs, this also
could be dropped but then it will always check if wxGraphicsContext can be
applied.
