[core.config] Make `parse_app_arg' a NOOP for tables.
[META] Use `core.config.parse_app_arg' uniformly.
[META] Refrain from using `([[{...}]]):format(...)' constructs
and use table literals instead.
[core.config] Remove type checking of `arg' in `config.app()'.
(It's done in `parse_app_arg'.)
Merge pull request #293 from eugeneia/app-table-args

Table app args refactoring
receive checksum offload
transmit checksum offload
the "insert checksum" bits of TXDESC must reflect the current context
precalculate the offload flags together with the context descriptor
check if the packet needs checksum before asking the chip to do it
add offload support for SCTP
test: start sending doctored packets to see if bad checksums are detected and if good ones can be inserted
adapt new selftest to #293 merge
