afbf94c 
…ebAssembly#112)

* Link `populate_args` only if we actually need command-line arguments.

This avoids linking in the argv/argc initialization code,
and the __wasi_args_sizes_get and __wasi_args_get imports, in
programs that don't use command-line arguments. The way this works is,
if the user writes `int main(int argc, char *argv[])`, the argument
initialization code is loaded, and if they write `int main(void)`,
it's not loaded.

This promotes the `__original_main` mechanism into an effective contract
between the compiler and libc, which wasn't its original purpose,
however it seems to fit this purpose quite well.

* Document that `__original_main` may be the user's zero-arg `main`.

Hi, I also found missing netdb.h in wasi-sdk. Could I trouble you to give some advices? Thank you very much.

WASI does not yet support the functionality needed to implement netdb.h. Before wasi-sdk can support it, we'll need WASI proposals to support it.
