Solution: checkout stable branch instead.
Several warnings are printed when building from the master branch,
and developers recommend using the stable branch instead.
Took me over 8 hours to track down the cause of bizarre link
errors when building with libsodium. The VS project files are
not simple things.
Note to self and other maintainers: when someone is obviously
out of their depth, do not merge their changes to build scripts
without cynical appraisal.
Solution: undo the damage.
Solution: when iterating over a map and conditionally deleting
elements, an erased iterator gets invalidated. Call erase using postfix
increment on iterator to avoid using an invalid element in the next
iteration.
Solution: parse the value set by the ZMQ_PRE_ALLOCATED_FD sockopt
when creating a new TCP socket and use it if valid.
Add new tests/test_pre_allocated_fd_tcp.cpp unit test.
Solution: parse the value set by the ZMQ_PRE_ALLOCATED_FD sockopt
when creating a new IPC socket and use it if valid.
Add new tests/test_pre_allocated_fd_ipc.cpp unit test.
Solution: add new [set|get]sockopt ZMQ_PRE_ALLOCATED_FD to allow
users to let ZMQ use a pre-allocated file descriptor instead of
allocating a new one. Update [set|get]sockopt documentation and
test accordingly.
The main use case for this feature is a socket-activated systemd
service. For more information about this feature see:

Caused by error in last commit which used HAVE_LIBSODIUM instead
of HAVE_SODIUM.
Solution: use HAVE_LIBSODIUM as we do in other configure scripts.
The project is called 'libsodium' and not 'sodium'.
There is an option to enable/disable libsodium via the Visual Studio
UI. This is not practical for command-line usage (via msbuild).
Solution: add configure.bat that searches for libsodium in sibling
directory to libzmq; if it finds it, defines HAVE_LIBSODIUM 1.
This is consistent with zproject, which has the same problem and
is getting the same solution for all dependency resolution on
Windows.
Note that this approach also provides a way to support tweetnacl
via a configure option.
Also, removed duplicate props files and re-copy in configure.bat
as it was an insane nightmare to update these by hand. (and not
clear that they were identical. Now it's forced.)
select was improved to support multiple service providers on Windows.
it should be slightly faster because of optimized iteration
over selected sockets.
I hope restoring this from a previous version doesn't do any damage, it
is missing in the current version of this repository and is vital for
the lib to compile anywhere.
