Keith Packard d18f5801c9 glamor: Add glamor_program based 0-width dashed lines 
This makes sure the pixelization for dashed lines matches non-dashed
lines, while also speeding them up.

v2: Switch to glamor_make_current

v3: Create dash pattern pixmap without GLAMOR_CREATE_FBO_NO_FBO

v4: Adopt suggestions from Eric's review:

  - Drops power-of-two alignment of our line vertex data, simplifying
    the code.

  - Stops reading from the VBO.  While on keithp's and my machines the
    VBO is mapped cached, on many implementations it will be mapped WC,
    making those reads extremely expensive.

  - Style fixes (line wrapping, spaces around operators).

v5: Adopt suggestions from Markus' review:

  - Use max when computing zero-width dashed line length.

    Don't open code max here.

  - Embed CoordModePrevious into VBO writing for dashed lines

    Instead of pre-computing the coord mode previous results, just
    embed this in the loop which fills the vertex buffer. Saves
    re-writing the request buffer, and shortens the code a bit

v6: Export glamor_destroy_gc for UXA

    UXA needs to call glamor_destroy_gc from its GCFuncs, so export
    it.
