dvbinfo: fix error: 'daemon' is deprecated: first deprecated in OS X 10.5 [-Werror,-Wdeprecated-declarations]

I'm not sure if you will want to apply this patch, but I thought I
should share it and let you decide.  I need it in order to build
libdvbpsi on OSX Mavericks, but I don't actually use the dvbinfo
program.

Fix the following build error when building under OSX:

I've noticed from commit f93983a7 &
the NEWS file that libdvbpsi is on version 1.2.0 now, but in the header
file dvbpsi.h, DVBPSI_VERSION still says 1.1.2 and DVBPSI_VERSION_INT
still says 1.1.1 ...

Beware using the AdressSanitizer from GCC 4.8 uses a lot of memory. You need
more then 8GB of memory in your machine.

Use strtoll(optarg, NULL, 10).

Check for p_stream to be a valid pointer.

Forgot to terminate the case for option 'a'.

Check filedescriptors for having a valid value.

Check i_fd to have a valid value.

pf_write() returns a ssize_t which was stored inside a size_t (an unsigned).
Later on this value was used in a check against 0.

The pointer to p_subdec should have been evaluated on line 119.

The wrong pointer was checked for having a null value leading to the
null pointer dereference bug.

The bug occurs due to a missing check for allocation failure of p_decoded->i_text.
Instead p_decoded is checked again.

The assert() dereferenced the p_dvbpsi pointer before it was checked for null-value.

The code does not leak a socket descriptor while looping over addrinfo pointer structs.However initializing s_ctl to -1 again after calling close(s_ctl) is good practise.
