  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_
# resample_
FILTER="${GREP} -v -e ^ast_ -e ^_ast_ -e ^__ast_ -e ^astman_ -e ^pbx_ -e ^resample_"
