fhandler_base::open_fs has two problems:
- When newly creating a file, the file info in the path_conv is
incorrect. It points to info for the parent dir, not to info
for the file itself (which, naturally, wasn't available before).
- Fetching the file's inode number only worked for non-NFS.
Both problems should be fixed now by reloading file info if the file
has just been created, as well as using the new FS-agnostic
path_conv::get_ino method.

This avoids having to call nfs_fetch_fattr3/file_get_fai depending
on FS type as well as having to extract the info FS dependent.

Rather than having to check for the FS type in the caller and having
to call different functions whether FS is NFS or not, encapsulate the
info in path_conv_handle/path_conv methods to allow FS type agnostic
calling from upper level functions.
This patch only implements the methods.

Commit a23e6a35d896a075640db714b28ce74bb6b8d7ff introduced a timer
object to the WFMO handling in select_stuff::wait to allow sub-tickcount
timeout values in select.
Problems with this patch: The timer was created and destroyed on every
invocation of select_stuff::wait, thus potentially multiple times per
select. Also, since the timer was prepended to the WFMO hande list,
the timer handle could shadow actual events on other objects, given that
WFMO checks the objects in the order they have been specified in the
HANDLE array. The timer was also created/destroyed and added to the
HANDLE array even if it was not required.
This patch drops the local timer HANDLE and recycles the cw_timer HANDLE
in the cygtls area instead. Thus we typically don't need to create the
timer in select at all, and we never have to destroy it.
The timer HANDLE is now also appended as last object to the HANDLE array,
and it's only added if actually needed.

The check for current timestamp > start timestamp has an unwelcome
side effect: The loop is not left as long as the current timestamp
hasn't been incremented. This leads to busy loops of about one tick
(10 to 16 ms per MSDN).

'man termios' says:
"A read(2) returns at most one line of input" in canonical mode.
On cygwin 2.5.1, read(2) returns all data in buffer if the buffer
size specified is large enough. This behaviour is correct in
noncanonical mode, but is not correct in canonical mode.
While checking this problem, I found a bug of tcflush(). tcflush()
flushes only partial data in the buffer. The patch also fixes this bug.
The patch has also been tested against the problem reported in
https://cygwin.com/ml/cygwin/2016-05/msg00318.html.

The rule to make tlsoffset{64}.h has a flaw. If cygtls.h can't be
built for whatever reason, it *still* regenerates tlsoffsets{64}.h,
just with size 0. If the bug is not in cygtls.h itself, this behaviour
breaks further building, because fixing the problem won't result in
regenerating tlsoffset{64}.h. Manual intervention is required.
Fix that by removing tlsoffsets{64}.h if gentls_offsets fails.

So far drive letter paths have been handled special since path_conv
leaves the incoming path untouched except for converting backslashes
to forward slashes. However, if the incoming path starts with a
long path prefix, the same problem occurs. Therefore handle all
paths starting with a backslahs the same way.

ARCompact processors (ARC 600 and ARC 700) require three "nop"s after the
"flag 1" instruction. Later ARC processors do not have this requirement, so
it is possible to reduce size of "_exit_halt" for them.

Initially crt0.S used a special function, declared as weak as a default
exception handler in interrupt vector table. To let user override individual
handlers, this function had multiple names - one for each IVT entry, which,
however, was terribly confusing for the debugger and user - because it
wasn't clear which symbol will be used as a function name in debugger.
Defining multiple separate functions - one for each handler, would resolve
the mess, but would increase code size of crt0.o.
To clean this up, this patch defines exception handlers as weak symbols as
well, but those are defined as just symbols, not functions, hence there
would be less confusion over what is what. At the same time, users still can
redefine exception handlers symbol by creating functions with respective
names.

In case the TZ variable is empty, Cygwin fetches timezone info from

The proper location for these functions has always been <stdio.h>, however
XPG4 and SUSv2 did mandate a duplicate declaration in <unistd.h>. cuserid
was dropped in SUSv3 (it was marked legacy since XPG4) and the ctermid
declaration in <unistd.h> was made optional and obsolete in SUSv4.

So far pthread::postcreate() only sets the thread priority at all, only
if the inherit-scheduler attribute is PTHREAD_EXPLICIT_SCHED. This
completely ignores the PTHREAD_INHERIT_SCHED case, since in contrast
to POSIX, a thread does not inherit its priority from the creating
thread, but always starts with THREAD_PRIORITY_NORMAL.
pthread_getschedparam() only returns what's stored in the thread attributes,
not the actual thread priority.
This patch fixes both problems.

So far the scheduler priority handling is not POSIX compatible.
The priorities use a range of -14 up to +15, which means it's not clear
if the POSIX-required return value of -1 in case of an error is *really*
an error or just the valid priority value -1. Even more confusing, -14
is the *max* value and 15 is the *min* value. Last but not least this
range doesn't match the POSIX requirement of at least 32 priority values.
This patch cleans up scheduler priority handling and moves the valid
priority range to 1 (min) - 32 (max). It also adds a function
sched_get_thread_priority() which will help to make thread priority
more POSIX-like.

This fixes a problem, where libgloss wouldn't be built for ARC processors,
even though it is actually supported. The original patch that introduced
support for ARC in libgloss hasn't been submitted to GCC maillist, hence
when top-level configure has been synced with GCC - this libgloss patch has
been effectively reverted.
Libgloss support for ARC has been accepted in GCC:

Sure, I've attached the patch.

Add a simple rawmemchr implementation. Use strlen for rawmemchr(s, '\0') as it is the
fastest way to search for '\0', and use memchr with an infinite size for other cases.
This is 3x faster for large sizes.

The following testcase:
$ cat > test.c <<EOF
#include <sys/select.h>
#include <sys/time.h>
EOF
$ gcc -c test.c
emits the following error:
/usr/include/sys/reent.h:276:3: error: expected specifier-qualifier-list befor
e ‘_fpos64_t’
_fpos64_t _EXFNPTR(_seek64, (struct _reent *, _PTR, _fpos64_t, int));
^
The reason is that the load order from sys/select.h includes sys/_types.h
before sys/config.h has been included from anywhere else. sys/_types.h
defines _fpos64_t only if __LARGE64_FILES is defined, but it never is in
this scenario. So sys/_types.h has to make sure to get the configuration
info by itself.
