Add scripts to remove/replace 'static' from functions.
Getting a backtrace out with missing functions makes the
backtrace much less useful. Some backtrace routines (such
as that used by Memento on Android) are incapable of
resolving static functions.
We therefore provide 2 scripts (scripts/destatic.sh and
scripts/restatic.sh) that respectively remove and replace
the 'static' from function definitions.
The scripts do not affect "static inline" or "static const"
definitions, and they are are restricted to working in the
source directory (excluding source/tools), thirdparty/mujs
and the platform/{java,android} directories.
The transformed source should NOT be checked in.
To avoid problems with clashing symbols, some functions are
renamed or tweaked slightly in this patch.
