ca4cfd556f Add optional deleter expression to GL function definitions. 
The expression follows the function definition separated by a ~ character,
and is a simple boolean expression built with operators && and || from the
elementary expressions "core" "forward" or a GL version number like "3.2".

Parentheses are not supported, && binds stronger than || and may be ommited,
i.e. "3.2 core" is equivalent to "3.2 && core".

60f39ed9fd Pass context profile mask and context flags to init functions. 
They will be needed to decide if GL functions are deprecated or removed.

e935fcad83 Load core function pointers before checking the extension string. 
For GL versions since 3.0 the glGetString() function is deprecated or removed,
and the right way to query extensions is glGetStringi(), but that has to be
loaded first.

Also instead of searching the whole extension string n times lookup the
known extensions in a static hash table. The hash table is built with
the gperf utility.

11e24d4a9b Hack in crude OSMesa support 
Mostly this is quick, "do nothing" ifdefs when built with
SYSTEM=linux-osmesa, to support the off-screen rendering mode of Mesa in
headless tests.  Support in glewinfo and visualinfo is enough to get
them compile, but insufficient for them to run successfully.
