When using strncpy the NUL-termination can go missing if the string to be copied is longer than the buffer.
Make sure the last character in the buffer is NUL.
If this really happens, the error (non-existing path due to truncation) will be caught during bind-ing.
Fixes the following warning:
/home/peterke/DEV/zoneminder/src/zm_comms.cpp: In member function ‘bool ZM::SockAddrUnix::resolve(const char*, const char*)’:
/home/peterke/DEV/zoneminder/src/zm_comms.cpp:207:10: warning: ‘char* strncpy(char*, const char*, size_t)’ specified bound 108 equals destination size [-Wstringop-truncation]
207 | strncpy(mAddrUn.sun_path, path, sizeof(mAddrUn.sun_path));

mLocalAddr is always nullptr and not used anywhere. So just use a local variable for
the time being.
The comms types will need an API rework since the current one is rather convoluted.
Postpone fixing this properly until then.
The Socket class collides with a class named the same way from liblive555. This confuses the linker and links the wrong object leading to a crash when connecting to the RTSP server.
With this commit a unified structure for includes is introduced.
The general rules:
* Only include what you need
* Include wherever possible in the cpp and forward-declare in the header
The includes are sorted in a local to global fashion. This means for the include order:
0. If cpp file: The corresponding h file and an empty line
1. Includes from the project sorted alphabetically
2. System/library includes sorted alphabetically
3. Conditional includes
Monitors with source type 'remote' can now be accessed over IPv6. This
code uses getaddrinfo(3) now instead of gethostbyname(3) - and changes a
lot of networking stuff which should be tested thoroughly.
