[PATCH RFC][makedumpfile 07/10] Supporting main() as the entry of eppic script

[Tao Liu <ltao@redhat.com>]

Previously only a function with usage or help functions is regarded as
the entry of eppic script. This constraint makes no sense because main()
is widely accepted, and people can easily get confused when writing eppic
script and blocked by the constraint. This patch will support main() as
an entry.
