Merge branch 'eit_updates+charset_fixes+multisteam_fixes+multistream_updates' of https://github.com/gfto/dvblast-1 into gfto-eit_updates+charset_fixes+multisteam_fixes+multistream_updates

Add support for multistream-id calculation using --multistream-id-pls-mode, --multistream-id-pls-code and --multistream-id-is-id options

Configuration of pilot/rolloff and multistream options was off-by-one
so basically they were never set as expected thus not working at all
(in the case of multistream).

Setting --lnb-type old-sky allows dvblast to work with some
Australian satellite services.

It is possible that 'dvblast' does not answer on the command socket
and in this case 'dvblastctl' just hangs waiting forever.

This commit introduces timeout for send/receive operations in dvblastctl.
The timeout is set in seconds and the default value is 15 seconds.

Sometimes broadcasters put "strange" characters in DVB strings and
when the strings are converted to UTF-8 the output contains
invalid characters.

In order to avoid this problem, this commit instructs iconv
library to ignore characters that can not be converted to
UTF-8 by adding switching the default output charset from
UTF-8 to UTF-8//IGNORE to the output charset.

New 'dvblastctl' commands:

  dvblastctl get_eit_pf <service_id>         - Print EIT present/following events and descriptors.
  dvblastctl get_eit_schedule <service_id>   - Print EIT schedule events and descriptors.

This stops sections from one table to overwrite sections in
another table (usually seen with section 0 from EIT/pf and EIT/schedule).

This increases memory usage by at least 32 kb per service
but allows extracting of complete EIT data.

They carry a lot of information and the log is filled up rapidly.
