This permits the stats dump to avoid some extra buffering,
and resolves a complaint about possible format buffer overruns.

fixes #267 zerotier transport should lock ZT_HOME
|
| |
|
|
|
|
|

This includes converting the ZeroTier transport to use these.
The new API supports file creation, retrieval, and deletion. It
also supports directory methods for traversal, creation, and
deletion. It also has a few methods to obtain well-known directories
like $TMPDIR and $HOME.
A rich test suite for this functionality is added as well.

We introduced richer, deeper tests for UDP functionality.
These tests uncovered a number of issues which this commit fixes.
The Windows IOCP code needs to support multiple aios on a single
nni_win_event. A redesign of the IOCP handling addresses that.
The POSIX UDP code also needed fixes; foremost among them is the
fact that the UDP file descriptor is not placed into non-blocking
mode, leading to potential hangs.
A number of race conditions and bugs along the implementation of
the above items were uncovered and fixed. To the best of our knowledge
the current code is bug-free.

Added TCP socket address properties on pipes.
This adds the plumbing for the various platform specifics, and
includes both v4 and v6 handling.
We've included a TCPv6 test as well.

We only compile files that are appropriate for the platform. (We
still have guards in place, to allow for a future single .C file
to be built from all the sources.) We also remove the subsystem defines;
if a new platform needs to deviate from POSIX in ways beyond what we
intended here, then that platform should just copy those parts into
a new platform directory, rather than cross including portions from
POSIX.

This is only lightly tested, and I expect that there remain
some race conditions. Endpoint logic in particular needs
work.

The IOCP code has been refactored to improve reuse, and hopefully
will be easier to use with TCP now. Windows IPC using Named Pipes
is mostly working -- mostly because there is a gnarly close-race.
It seems that we need to take some more care to ensure that the
pipe is not released while requests may be outstanding -- so some
deeper synchronization between the IOCP callback logic and the
win_event code is needed. In short, we need to add a condvar to
the event, and notice when we have submitted work for async completion,
and make sure we flag the event "idle" after either completion or
cancellation of the event.

Modern Windows (Vista and later) have light weight Slim Read/Write locks
which only occupy 64 bits, and don't require any memory allocation to
create.
While here clean up a few more unreferenced variables found with the
Microsoft compilers.

Test code needs to use the static libraries so that they can get access
to the entire set of symbols, including private ones that are not exported.

There are lots of changes here, mostly stuff we did in support of
Windows TCP. However, there are some bugs that were fixed, and we
added some new error codes, and generalized the handling of some failures
during accept. Windows IPC (NamedPipes) is still missing.
