With this change, the signal handler signature is defined in only one place.
Also make most signal handler functions static (those that are only referred to in irc.c).
irc_std.h is where these belong - it's where the normal declarations (via the system headers) come from on
systems which don't need the compat functions.
The function provided (either by #define to the module table or directly in the case of scr-bx.c)
is called my_ltoa(), and the #define in irc_std.h aliases this to ltoa().
Identifiers beginning with two underscores or one underscore and a capital
letter are reserved in all contexts, including macros.
The __N macro in irc_std.h is in this space, and was conflicting with a macro
definition in gcc 5.4.0's xmmintrin.h under cygwin, making the build fail.

Only include <netinet/in.h> and <sys/socket.h> if the system supplies them.
This is necessary to try and get the mingw32 build working again.
No need to include <sys/types.h> and <netinet/in.h> from cdns.c - these are
already included by <irc.h>.
<fcntl.h> is the name used by POSIX, so we prefer this and only fall back to
<sys/fcntl.h> on non-POSIX systems. Fixes warnings compiling against musl
libc.
