After Stage merge #6993 I lost sntp functionality

[arendst]

Using Tasmota on Arduino core stage after merge #6993 I lost sntp functionality and compilation fails with Undefined References to the once documented SNTP API calls by espressif:

• sntp_get_real_time
• sntp_get_current_timestamp
• sntp_set_timezone

I guess some functionality has been dropped...

For sntp_get_real_time I'll make a workaround saving 1k code space anyway. The others still break compilation

Sorry for that @arendst I focus too much on internals and Arduino API, not espressif API :]
I will re-add these asap.

@arendst sntp_get_real_time() returns this string.

ctime() would return Mon Mar 4 21:22:16 2019 so I guess it'd be what you expect, do you confirm ?
I'll propose wrappers mocking espressif API around callers to standard functions.

@d-a-v confirmed.
