Linear memory is optional in WASM. Protect against crashes when a WASM doesn't use it.

fix eosioc set contract with wasts

Call wasm start func each time

376 migration ofr account history plugin needs gcc fix

whoops!

Previously, the WASM "start" function would be called once right after compilation. This was problematic for two reasons. 1) It was called during a period of time not expected (not during any context), and 2) if the user was expecting the start function to be called for initialization it would not be called after the memory had been reset on subsequent apply() calls -- that could be a surprise.

Now call the WASM "start" function before each init() and apply().

@DAWN-391  added sbrk and fixed the function signature of memset

@DAWN-390 fixed issue with sbrk not clearing between actions, and added page resizing to cache checkin to ensure page size goes back to default

DAWN-376 account history plugin migration

Import eos-walletd from master and rename it to eosio-walletd.

Update to appbase revision that fixes config filename customization.

Resolves #1065.

Reload logging.json on receipt of SIGHUP.

allow passing binary WASM to eosioc set contract (in addtion to WAST)

fix the write scope for setting contracts in eosioc in noon

logging_conf_loop() duplicates everything initialize_logging() does but
with error handling intentionally omitted from initialize_logging().
Startup requires a good logging.json, but reload tolerates a bad one.
Good daemons always keep running as best they can once started, but can
insist on a good startup environment.

Some toolchains output binary WASM directly; it's nice to not need WASM->WAST translation before setting the contract via eosioc
