mesa: if MESA_DEBUG=context, create a debug context

A number of drivers report useful debug/perf information accessible
through GL_ARB_debug_output and with debug contexts (i.e. setting the
GLX_CONTEXT_DEBUG_BIT_ARB flag).  But few applications actually use
the GL_ARB_debug_output extension.

This change lets one set the MESA_DEBUG env var to "context" to force-set
a debug context and report debug/perf messages to stderr (or whatever
file MESA_LOG_FILE is set to).  This is a useful debugging tool.

The small change in st_api_create_context() is needed so that
st_update_debug_callback() gets called to hook up the driver debug
callbacks when ST_CONTEXT_FLAG_DEBUG was not set, but MESA_DEBUG=context.

The EGL 1.5 spec states that pbuffers have a back buffer but no front
buffer, single-buffered surfaces with no front buffer confuse Mesa;

egl: Use pkg-config for Android NDK build

It's possible to build Mesa for Android using the traditional
autotools workflow [1]. ChromiumOS fetches Android prebuilts and
puts them in a sysroot. We now want to use pkg-config to specify
the location of system headers and libraries [2].

To enable this, let's add the required pkg-config checks and link
against them.

configure.ac: Don't look for pthreads in Android platform

In Android, the pthreads libs are in bionic.  When building

dir-locals.el: Adds White Space support

Trailing white spaces will be now always highlighted, not just in
prog-mode.

Also, the White Space package, which is available since GNU Emacs 22,
is loaded and activated locally in prog-mode.

Additionally, using White Space variables, we set highlighting through
faces on wrong indentation and the maximum length of a coding line.

Notice that:
 - The highlighting for the characters beyond the set length of a
   coding line is not activated by default, only for wrong
   indentations.
 - If the White Space package is not available, errors on loading or
   activation are ignored.
 - If the White Space mode is not activated the set variables would
   not have any effect.

v2: Removed too long lines trail highlighting, as suggested by Ilia
