Simplify code in that it only fetches a single entry per
IEnumShellItems::Next call. For some reason this appears to
be quicker most of the time.

This should prevent printf output from multiple threads getting garbled.
I don't know why IO ever worked properly -- probably it was always a bit
broken -- but the GFX11 devices have a different cache architecture and
trying to print from many threads at once corrupted the FILE buffers.

Checking server existence by trying to enumerate its shares
may result in 2 minutes delay until some internal timeout is hit.
In the light that every network is an IP network anyway these
days, let's try with a simple getaddrinfo() call. This is usually
back in 3 secs even if the server doesn't exist, and it's usually
back in 8 secs if the DNS server can't be connected. This is the
fastest method I found to check server existence yet.

So far the check for a directory is in the fhandler::opendir
methods. Given that path_conv::check sets FILE_ATTRIBUTE_DIRECTORY
on virtual files either, we can move the check up into the
opendir(3) function. This avoids calling exists() twice when
calling opendir(3).

This reverts commit a51147467e6cf58618433286f93d17043e00b0fc.
Dumb thinko on my part. What was supposed to be an optimization
actually broke caseinsensitive globbing in that the entire input
of globbed expressions were downcased.
Drop the unused CCHAR() macro nevertheless.

If pipe reader is a non-cygwin app first, and cygwin process reads
the same pipe after that, the pipe has been set to bclocking mode
for the cygwin app. However, the commit 9e4d308cd592 assumes the
pipe for cygwin process always is non-blocking mode. With this patch,
the pipe mode is reset to non-blocking when cygwin app is started.

Since commit 15e82eef3a40b ("Cygwin: getgrent: fix local SAM enumeration

if we also enumerate AD. However, there are two local accounts which
are only available in local SAM, not in AD. Don't skip enumerating
those.

Chances are high that Cygwin recalls offline files from remote
storage, even if the file is only accessed during stat(2) or
readdir(3).
To avoid this
- make sure Cygwin is placeholder-aware,
- open files in path_conv handling, as well as in stat(2)/readdir(3)
scenarios with FILE_OPEN_NO_RECALL, and
- during symlink checking or testing for executablility, don't even
try to open the file if one of the OFFLINE attributes is set.

This patch eliminates verbose NtQueryObject() calls in the procedure
to get query_hdl by storing pipe name into fhandler_base::pc when

The open() call for console sometimes fails if the console owner
process is closing the console by close() at the same time. This
is due to mismatch state of con.owner variable and attaching state
to the console. With this patch, checking con.owner and attaching
to con.owner sequence in open(), and resetting con.owner and freeing
console sequence in close() are guarded by output_mutex to avoid
such a race issue.

In the condition that console setup for CTTY and close run at the

may occur. With this patch, to avoid this race issue, shared console
memory which belongs to contorolling terminal (CTTY) is kept mapped
as before.
