Fix compressed texture loads for non-minimal pitches again
My commit eea6a7639f does a memcpy of height
lines, but that's wrong because the texture has a block layout and we
must thus use the number of vertical blocks instead of the height.

pipebuffer: Reapply the mesa_7_7_branch's changes.
After the last mesa_7_7_branch merge the old master code remained,
instead of the newer mesa_7_7_branch's code. This commit makes both
branches match, modulo interface changes.
Note: future mesa_7_7_branch -> master merges will most likely hit
conflicts in these files. Unless otherwise stated, the mesa_7_7_branch
is the reference.
st/mesa: fix int->uint conversion for negative scissor bound values
Based on a patch by Xavier Chantry <chantry.xavier@gmail.com>:
If x+width or y+height is negative, then maxx or maxy will get a bogus value
when converting that to unsigned. Fix this by setting 0 as minimal value.
This was also triggered by teeworlds, but only with some combination of
resolution and map section. For example upper part of dm2 at 1280x1024.
commit 53174afeeb introduced a portability change that converted GLint x,y
to GLuint. That breaks when x and y are negative, which seems to be allowed,
and which at least one game uses : teeworlds.
Rather than simply reverting the change, it seems possible to convert the
16bit unsigned to GLint so that comparisons are made between signed integers
instead. This hopefully does not break anything while keeping MSVC happy.

nv50: fix crash in nv50_pre_pipebuffer_map (nv50_screen->cur_ctx)
nv50_pre_pipebuffer_map references screen->cur_ctx which points
to freed memory after the context is destroyed.
This crash is easily triggerable by progs/xdemos/glxcontexts.
Add a platform specific function to turn a library name to a library
path. It is used to convert EGL_DRIVER or the default driver to a
library path that can be loaded.
Make sure glapi headers are cleaned when "make clean". Make sure all
sources depend on subdirs-stamp-tmp so that sources/headers are
generated first.
subdirs-stamp-tmp will be removed after a successful build. It might be
a problem when a build fails. But it is much better than where we
currently are: glapi headers are never cleaned or re-generated.
