Subject: system for looking up static symbols

 * symbols are extracted from C header files by a TECO macro
 * macro is executed using a "minimal" version of SciTECO that does not include symbols (uses gcc's weak symbols)
 * the generated C++ code contains the symbol-name-to-define mapping as a constant sorted array and initializes the appropriate SymbolList object
 * a symbol lookup is super fast using a simple binary search in the symbol lists
 * except for object initialization, no there's no overhead for keeping the symbol lists!
 * build process is complicated by introduction of bootstrapping via sciteco-minimal
