Given that 64 bit Cygwin defines all file access types (off_t,
fpos_t, and derived types) as 64 bit anyway, there's no reason
left to rely on the stdio64 part of newlib. Use base functions
and base types.

- Previously, LoadLibraryA() is hooked for ConEmu cygwin connector.
With this patch, GetProcAddress() for "RequestTermConnector" is
hooked instead which is more essential for ConEmu cygwin connector.
- Recent commit "Cygwin: console: Add missing input_mutex guard."
has a problem that causes NULL pointer access if cygheap->ctty
is NULL. This patch fixes the issue.
gdb master recently learnt how to use GetThreadDescription() [1], so set
threadnames using SetThreadDescription() [available since Windows 10
1607] as well.
This is superior to using a special exception to indicate the thread
name to the debugger, because the thread name isn't missed if you don't
have a debugger attached at the time it's set.
It's not clear what the encoding of a thread name string is, we assume
UTF8 for the moment.
For the moment, continue to use the old method as well, for the benefit
of older gdb versions etc.

Back in early Cygwin development a function based access to the
environment was exported, the internal environ in Cygwin was called
__cygwin_environ and cur_environ() was used to access the environment
indirectly . The history of that necessity is not documented,
but kept in i686 for backward compatibility.
The x86_64 port eventually used __cygwin_environ directly and exported
it as DATA under the usual name environ.
We don't need the i686 workaround anymore, so just rename
__cygwin_environ to environ, drop the cur_environ() macro and
simply export environ under its own name.

- rename "is64bit" to "is_x86_64"
- Always set sym_prefix to empty string and add a FIXME
- speclib: rename uscore to sym_prefix and fix bug in string handling

- ConEmu cygwin connector conflicts with cons_master_thread since
it does not use read() to read console input. With this patch,
cons_master_thread is disabled in ConEmu cygwin connector.
Somehow this patch looks like it was pushed before having been
finished. Let's try again...

Only the assembler snippet is really x86_64-specific, so minimize the
conditional code block to this snippet.

Add a _REENT_CLEANUP() macro to encapsulate access to the
__cleanup member of struct reent. This will help to replace the
struct member with a thread-local storage object in a follow up
patch.
Add a _REENT_ERRNO() macro to encapsulate the access to the
_errno member of struct reent. This will help to replace the
structure member with a thread-local storage object in a follow
up patch.
Replace uses of __errno_r() with _REENT_ERRNO(). Keep __errno_r() macro for
potential users outside of Newlib.
- OpenClipboard() just after CloseClipboard() sometimes fails. Due
to this, /dev/clipboard sometimes fails to set CF_UNICODETEXT
data. This patch add a workaround for this issue.
Define FD_SETSIZE (<sys/select.h>) to be 1024 by default, and define
NOFILE (<sys/param.h>) to be OPEN_MAX (== 3200) by default.
Remove the comment in <sys/select.h> that FD_SETSIZE should be >=
NOFILE.
Bump API minor.

- With this patch, the empty path (empty element in PATH or PATH is
absent) is treated as the current directory as Linux does. This
feature is added for Linux compatibility, but it is deprecated.
POSIX notes that a conforming application shall use an explicit
pathname to specify the current working directory.

This reverts commit 1f8f7e2d54, "* libc/stdio/refill.c (__srefill):
Try again after EOF on Cygwin." If EOF is set on a file, the stdio
input functions will now immediately return EOF rather than trying
again to read. This aligns Cygwin's behavior to that of Linux.

- poll() has a bug that it returns event which is not inquired if
events are inquired in multiple pollfd entries on the same fd at
the same time. This patch fixes the issue.
