of gcc to try and force them to not complain with -Wall but to always
include this, I decided to take a simpler approach. All these strings
now have global linkage. To prevent namespace conflicts they all
have different names. For the record, the variable extension is a hash made of the first ten characters of the md5sum of the file path, eg:
md5hash=`boinc/api/x_opengl.C | md5sum | cut -c 1-10`

- In graphics_lib.h, this is for compatibility with pure C
applications.
- In graphics_impl.h, this would be needed EVEN if we were
never building app or library with anything other than C++.
It's because dlsym() can only work if you pass it a non-name
mangled symbol. Please see:

for futher edetail.
- Comments added to graphics_lib.C, better error message.

it. Please read comments in-line. I think the major
shortcoming is
that most (all?) apps will want to use 'handle' to resolve their
own functions to communicate data from worker to app graphics.
Perhaps we should provide an additional argument to
boinc_init_graphics_lib() for that purpose? At the right point,
after sucessful dlopen(), boinc_init_graphics_lib() will call
that user-supplied function (if not NULL) passing it handle.
On return boinc_init_graphics_lib() will then carry on and start
graphics.
It's fun working on a file that's not in Makefile. No guilt!
