Since commit 8128f5482f, we have all the
non-tracing functions listed in posixoptions(7). The tracing functions
are gated by their own option, and are obsolecent anyway.

* Don't use a bool var to store three states (-1, 0, 1).
* Correctly check for NT_SUCCESS of a function returning NTSTATUS.
* Straighten out code for better readability.

Commit 603ef545bd broke this snippet and
commit 5b312b4747 didn't help at all since
FILE_CREATE is exactly *not* the situation the test was originally
supposed to handle.
In fact, none of the open flags used by fhandler_base::open actually
hits this problem anymore, so just drop the code.

Difference to Linux: We can't create files which don't show up
in the filesystem due to OS restrictions. As a kludge, make a
(half-hearted) attempt to hide the file in the filesystem.

* Fix the maximum number of sockets allowed in the session to 2048,
instead of making it relative to sizeof(wsa_event).
The original choice of 2048 was in order to fit the wsa_events array
in the .cygwin_dll_common shared section, but there is still enough
room to grow there to have 2048 sockets on 64-bit as well.
* Return an error and set errno=ENOBUF if a socket can't be created
due to this limit being reached.

Also updates the fhandler_*::ftruncate implementations to adhere to the same
semantics. The error handling semantics of those syscalls that use
fhandler_*::ftruncate are moved to the implementations of those syscalls (
in particular ftruncate() and friends still set errno and return -1 on error
but that logic is handled in the syscall implementation).
Under some not quite clear conditions, NFS fails to use its
unlink workaround to rename a file to ".nfsXYZ". The problem has been
reproduced with the GAWK testext.awk testcase. To workaround this in
Cygwin, we now call try_to_bin on NFS, too. For some reason NFS doesn't
fail to rename the .cygXYZ file to .nfsXYZ after this Cygwin rename.
Fix comment in unlink_nt accordingly.

The "final trick" code in try_to_bin accidentally never worked on
remote drives because it relies on rootdir. Which isn't set for
remote unlinks. The code now creates a full path for remote files.

The try_to_bin function isn't called for netapp FSes anyway, so testing
for this FS type in the function is moot.

The first argument of gethostbyaddr needs to accept a generic pointer
to be compatible with e.g. struct in_addr *. This caused an issue
compiling krb5-1.15.

herror etc. are MISC, rcmd etc. are BSD, addrinfo functions are
POSIX.1-2001, except for IDN functionality which is GNU.

When fork fails, we can use "%s" now with system_sprintf for the errmsg
rather than a (potentially too small) buffer for the format string.
* fork.cc (fork): Use "%s" with system_printf now.
With "%C" format string, argument may convert in up to MB_LEN_MAX bytes.
Relying on sys_wcstombs to add a trailing zero here requires us to
provide a large enough buffer.
* smallprint.c (__small_vsprintf): Use MB_LEN_MAX+1 bufsize for "%C".
The third argument of RtlLookupFunctionEntry actually is documented as
_Inout_opt_ for both x64 and ARM, although generic doc says _Out_ only.
* exceptions.cc (__unwind_single_frame): Initialize hist variable.
