Entering nsock_loop() with the poll engine activated and no registered FD
(timers only, for instance) should not directly return, but sleep until next
timeout.
Changes:
* Fix a collision of the name PS_NONE with a different constant in shlobj.h
* Update solution and project files for VS2013
* Update the NSIS installer to reference the VC 2013 redistributable
Some errors were not properly propagated. Ensure proxy_resolve() returns
a negative error code and make the caller fatal() when unable to complete
proxy_chain initialization for whatever reason.
Report finished (likely failed) events as early as possible. Because the
corresponding IODs can have no I/O activity, they wouldn't be flagged as active
by the I/O engines and the events could end up being delivered at shutdown only
(or never).

Only FD_SET and FD_CLR were available. Added a FD_ISSET equivalent.
Implemented them as static inline instead of macros for consistency.
These functions abort() if the FD number is higher than FD_SETSIZE
(except on windows where no check is performed).
This wasn't using Nmap's included libpcap if no options were specified,
instead compiling nsock without pcap support if no libpcap could be
found (which breaks Nmap)
Using offsetof instead of actually dereferencing a 0 pointer is still
standards compliant (works under gcc -ansi, clang -ansi), and is more in
line with how Linux kernel defines this macro (kernel.h). Can't exactly
lift the kernel implementation because it uses gnu-extension typeof.
Not really a necessary change, but it was causing clang's address
sanitizer to complain.

Move some includes out of nmap.h: nmap.h gets included lots of places,
and unconditionally included math.h, ctype.h, errno.h, stdio.h,
sys/stat.h, fcntl.h, sys/types.h, and stdarg.h. This commit moves those
includes into the .cc files where they are necessary and out of nmap.h
Remove redundant include global_structures.h, included from nmap.h
Removed redundant code included from nmap.h
Removing #include nbase.h when nmap.h is included (redundant)
Remove duplicate #include lines
Add ifndef guards to a few .h files
