Revert "Add non-executable stack markings to imgproc_sse2.asm"

This reverts commit 871f85159a88ed5f6c528c81462d8bfd0ab8fc21.

These declarations already exist in libol/x86inc.asm, so 871f851 has no useful
effect but yields this new warning:

    libol/imgproc_sse2.asm:42: warning: section flags ignored on section redeclaration

Dynamic font types: olGetFont(), olFreeFont() framework

This framework allows for the implementation of different font types including
dynamically loaded fonts.  Fonts are allocated and loaded via e.g.:

	Font *font = olGetFont(OL_FONT_SOMETHING, "somefontname");

Only OL_FONT_DEFAULT is currently implemented, hence:
	olGetFont(OL_FONT_DEFAULT, "unused")
is equivalent to:
	olGetDefaultFont()

olFreeFont(font) should be called to free fonts returned by olGetFont(),
though freeing the default font is unnecessary (but harmless).

No functional change (until some future type is implemented).

Hershey fonts support via libhersheyfont

If the libhersheyfont library is installed, build with support for
Hershey vector fonts.  Adds new olFontType OL_HERSHEY_FONT, e.g.:

    Font *olGetFont(OL_HERSHEY_FONT, fontname);
    ...
    olFreeFont(font);
