Corinna Vinschen 2902b3a09e Cygwin: drop requirement to build newlib's stdio64
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.

Cygwin: Set threadnames with SetThreadDescription()
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.

Corinna Vinschen 7f42498be6 Cygwin: rename __cygwin_environ and drop env redirection via cur_environ()
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.

Matt Joyce ea99f21ce6 Add --enable-newlib-reent-thread-local option
By default, Newlib uses a huge object of type struct _reent to store
thread-specific data.  This object is returned by __getreent() if the
__DYNAMIC_REENT__ Newlib configuration option is defined.

The reentrancy structure contains for example errno and the standard input,
output, and error file streams.  This means that if an application only uses
errno it has a dependency on the file stream support even if it does not use
it.  This is an issue for lower end targets and applications which need to
qualify the software according to safety standards (for example ECSS-E-ST-40C,
ECSS-Q-ST-80C, IEC 61508, ISO 26262, DO-178, DO-330, DO-333).

If the new _REENT_THREAD_LOCAL configuration option is enabled, then struct
_reent is replaced by dedicated thread-local objects for each struct _reent
member.  The thread-local objects are defined in translation units which use
the corresponding object.

Matt Joyce 1a09082036 Add _REENT_IS_NULL()

Konrad Sewiłło-Jopek cf2ba7d7f8 arp: Implement sticky ARP mode for interfaces.
Provide sticky ARP flag for network interface which marks it as the
"sticky" one similarly to what we have for bridges. Once interface is
marked sticky, any address resolved using the ARP will be saved as a
static one in the ARP table. Such functionality may be used to prevent
ARP spoofing or to decrease latencies in Ethernet networks.

The drawbacks include potential limitations in usage of ARP-based
load-balancers and high-availability solutions such as carp(4).

The implemented option is disabled by default, therefore should not
impact the default behaviour of the networking stack.

Alan Somers 27dfb5f33f Correctly measure system load averages > 1024
The old fixed-point arithmetic used for calculating load averages had an
overflow at 1024.  So on systems with extremely high load, the observed
load average would actually fall back to 0 and shoot up again, creating
a kind of sawtooth graph.

Fix this by using 64-bit math internally, while still reporting the load
average to userspace as a 32-bit number.
