Fixing udp.d.ts

[linfan68]

Found an Error on the .d.ts file (Buffer should be the 3rd argument), refer to different native c code:

moddable/modules/io/socket/win/udp.c

Line 226 in 2945c5d

xsmcGetBufferReadable(xsArg(2), &buffer, &byteLength);

moddable/modules/io/socket/lin/udp.c

Line 233 in 2945c5d

xsmcGetBufferReadable(xsArg(2), &buffer, &byteLength);

moddable/modules/io/socket/lwip/udp.c

Line 197 in 2945c5d

xsmcGetBufferReadable(xsArg(2), &buffer, &byteLength);

moddable/modules/io/socket/mac/udp.m

Line 237 in 2945c5d

xsmcGetBufferReadable(xsArg(2), &buffer, &byteLength);

Yikes!

You are correct that udp.d.ts is out of sync with the implementations. But.... the implementations are wrong! Checking the standard for UDP, the buffer argument is first. That's consistent with the IO Class Pattern which always defines the first argument as the data to be written and leaves the remaining arguments, if any, to the particular class.

I think the implementations should be fixed. That will break some code. Best to do that sooner than later. For the transition, I can check for the first argument being a string and issue a specific exception about the needed change.
