Improve the build system to *properly* remove unnecessary symbols from the runtime global namespace. Along the way, change the prefixes on some internal-only API calls to use a common prefix.

With these changes, for a module to export symbols into the global namespace, it must have *both* the AST_MODFLAG_GLOBAL_SYMBOLS flag and a linker script that allows the linker to leave the symbols exposed in the module's .so file (see res_odbc.exports for an example).

-# This script is designed to remove all non-API global symbols from an object
-# file. The only global symbols that should be retained are those that belong
-# to the official namespace. Unfortunately doing this is platform-specific, as
-# the object file manipulation tools are not consistent across platforms.
-#
-# On platforms where this script does not know what to do, the object file
-# will retain non-API global symbols, and this may have unpleasant side effects.
-#
-# Prefixes that belong to the official namespace are:
-#	ast_
-#	_ast_
-#	__ast_
-#	astman_
-#	pbx_
