i965: Use sendc for all render target writes on Gen6+.

The sendc instruction causes the fragment shader thread to wait for
any dependent threads (i.e. threads rendering to overlapping pixels)
to complete before sending the message.  We need to use sendc on the
first render target write in order to guarantee that fragment shader
outputs are written to the render target in the correct order.

Previously, we only used the "sendc" instruction when writing to
binding table index 0.  This did the right thing for fragment shaders,
because our fragment shader back-ends always issue their first render
target write to binding table index 0.  However, it did the wrong
thing for blorp, which performs its render target writes to binding
table index 1.

A more robust solution is to use sendc for all render target writes.
This should not produce any performance penalty, since after the first
sendc, all of the dependent threads will have completed.

shared-glapi: Install libglapi.so.0.0.0 and .0 links in lib/.

We already provided these files on 'make install', but only created a
'libglapi.so' in the top-level lib/ convenience folder.  We used to
create all three, but at some point in the build system churn, it broke.

Various applications (like the ES2 conformance suite) seem to link
against libglapi.so.0, so without these links, setting LD_LIBRARY_PATH
and LIBGL_DRIVERS_PATH can lead to using /usr/lib/libglapi.so.0 with
/home/whatever/libGL.so, which leads to API calls getting routed
incorrectly (i.e. glCompileShader -> _mesa_LinkProgramARB), which leads
to rage problems.

Preserve developer sanity...install links.

Remove redundant osmesa shared library install from Makefile.old

Since osmesa now has been converted to Makefile.am, an appropriate install: rule
is generated to install the shared libary, so we no longer need to do that in
src/mesa/Makefile.old

This leaves nothing in src/mesa/Makefile.old but the tags: rule, so move that to
Makefile.am and remove Makefile.old

Also, nothing now uses OSMESA_LIB_GLOB anymore, so remove it

Commit 6c6803f28de0d4cb6937fcd95a47aa81da31fd78 removed xm_image.[ch], and removed
xm_image.c, but not xm_image.h from the Makefile, this was subsequently carried over
