This library implements libgloss input/output and setup
routines for UART 8250 devices of ARC development boards:
* EM Starter Kit
* HS Development Kit
* EM Software Development Platform
* IoT Development Kit
_uart_8250_setup function with proper parameteres must be called
to setup UART 8250 device for a particular board (refer to
a board's documentation).

There is a special interface built in ARC simulators (such as
nSIM) called MetaWare hostlink IO which can be used to implement
system calls. This commit adds support for this interface to the
ARC port of libgloss.
Here is an example of using this interface:
$ arc-elf32-gcc -mcpu=hs -specs=hl.specs main.c -o main
$ nsimdrv -tcf $NSIM_HOME/etc/tcf/templates/hs48_full.tcf main
Hello, World!

Assembler for ARCv2 always extends the name provided by
.file directive to an absolute form.
On ARCv3 targets .file directive forces assembler to put
a provided string to DW_AT_name field as is without
extending to an absolute path. Then GDB cannot find
source files because of it.
The best way to fix this issue is just delete lines
with .file directive in .S files and let the compiler
to decide what DW_AT_name must contain. Particularly,
the compiler fills this filed by an absolute path to
a .S file because only absolute paths are used in
toolchain's build process.

ARC supports a restricted register file with 16 registers.
However, optimized routines support only a full register
file. Thus, fallback on default implementation in case
of 16-entry register file.

According to GCC documentation for ARC, a function marked with
the long_call attribute is always called using register-indirect
jump-and-link instructions, thereby enabling the called function
to be placed anywhere within the 32-bit address space.
exit_halt function is provided by crt0.S and it's used
in nsim-syscalls.c. Thus, we want to ensure that a linkage
issue will not arise.

While commit 0321fb5736 ("Cygwin: glob: convert wchar_t to wint_t")
switched the entire glob mechanism from wchar_t to wint_t, the globify
function calling glob on a DOS command line did not catch up and only
checked for the next character constituting a 16 bit wchar_t. This
broke reading surrogate pairs from incoming DOS command lines if the
string had to go through glob(3).
Check for an entire 32 bit unicode char instead.

Commit a0a25849f9 ("Cygwin: fhandler_virtual: move fileid to path_conv
member") broke `ls -l /proc/<PID>'. Turns out, the commit forgot to set
the fileid in case of a virtual root dir (i. e., returning virt_rootdir)
in fhandlers utilizing fileid. This crashed opendir() due to a random
fileid.
Make sure to set fileid in any case.

Commit 80f722e97c ("Cygwin: opendir(3): move ENOTDIR check into main
function") introduced a bug in fhandler_virtual handling. While the
assertion that path_conv::check() already calls exists() and sets
FILE_ATTRIBUTE_DIRECTORY accordingly, the exists() function is called
on a fhandler_virtual object created for just this code snippet. The
side effect of this is that the fileid member in the calling
fhandler_virtual object is not set after path_conv::check().
Move the fhandler_virtual::fileid member to path_conv::_virt_fileid
and create matching path_conv::virt_fileid() and fhandler_virtual::fileid()
methods.
Let path_conv::check() propagate the fileid set in the local
fhandler_virtual::exists() call to its own _virt_fileid.
Use new fhandler_virtual::fileid() method throughout.

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).

the same pipe after that, the pipe has been set to bclocking mode
