Solution: Phase I - make precompiled.hpp be first file included in every source file

used static_cast<signed int> around WSA_WAIT_FAILED as it is an unsigned implicitly defined as (0xFFFFFFFF ion winbase.h) and causes a comparison error.

removed use of c++11 style initialiser list for 'sockaddr addr { 0 }' and changed it to 'sockaddr addr = { 0 }'

select was improved to support multiple service providers on Windows.
it should be slightly faster because of optimized iteration
over selected sockets.

Solution: update to 2016

Of course people still "can" distributed the sources under the
LGPLv3. However we provide COPYING.LESSER with additional grants.

Solution: specify these grants in the header of each source file.

Solution: update for 2015

Fixes #1320

For OS X, the microseconds field is implemented as an int type. The implicit narrowing in the initializer list throws a compiler error for some compilers with C++11 support turned on. The specific error message is: "error: non-constant-expression cannot be narrowed from type 'long' to '__darwin_suseconds_t' (aka 'int') in initializer list [-Wc++11-narrowing]".

Tested on Clang 5.1.0 and Mac OS X 10.9.4.

Copyrights had become ads for Sustrik's corporate sponsors, going against the original
agreement to share copyrights with the community (that agreement was: one line stating
iMatix copyright + one reference to AUTHORS file). The proliferation of corporate ads
is also unfair to the many individual authors. I've removed ALL corporate title from
the source files so the copyright statements can now be centralized in AUTHORS and
source files can be properly updated on an annual basis.

Till now wrappers for all the polling mechanisms available on
the given platform were compiled, although only one of them
was used. This patch compiles just the used one. This can
make libzmq binary more concise.

If, when compiling 0MQ you don't set FD_SETSIZE,
it defaults to 1024 rather than to 64.

Since executing the timers might modify the source pollsets we have
to defer the initialisation until after the timers have executed.

Ensure that 0MQ does not attempt to call select() on more than FD_SETSIZE
file descriptors.

I was hitting an issue with an SCL enabled STL library in connection with the
way select_t::loop was erasing retired fd's. The problem as identified by the
SCL assertion was that by the time the iterator given to the erase method was
called it was considered invalid by the library. I am not sure this isn't just
a "quirk" of the MSVC STL library as the other code looks valid to me as well.
