0d57ef9de5 Cygwin: open: Remove unused code to handle HIDDEN and SYSTEM files
Commit 603ef545bdbdbf7495e1a0bbabffb8741fc2a5bb broke this snippet and
commit 5b312b4747cc4acda39c187369c02fcea456513b didn't help at all since
FILE_CREATE is exactly *not* the situation the test was originally
supposed to handle.

In fact, none of the open flags used by fhandler_base::open actually
hits this problem anymore, so just drop the code.

1c50e0d1ab Fix two bugs in the limit of large numbers of sockets:
* Fix the maximum number of sockets allowed in the session to 2048,
  instead of making it relative to sizeof(wsa_event).

  The original choice of 2048 was in order to fit the wsa_events array
  in the .cygwin_dll_common shared section, but there is still enough
  room to grow there to have 2048 sockets on 64-bit as well.

* Return an error and set errno=ENOBUF if a socket can't be created
  due to this limit being reached.

94854321bb posix_fallocate() *returns* error codes but does not set errno
Also updates the fhandler_*::ftruncate implementations to adhere to the same
semantics.  The error handling semantics of those syscalls that use
fhandler_*::ftruncate are moved to the implementations of those syscalls (
in particular ftruncate() and friends still set errno and return -1 on error
but that logic is handled in the syscall implementation).

56e494c074 fix internal __ieee754_expf and __ieee754_logf calls
The recently added new math code inlines error handling instead of using
error handling wrappers around __ieee754* internal symbols, and thus the
__ieee754* symbols are no longer provided.

However __ieee754_expf and __ieee754_logf are used in the implementation
of a number of other math functions.  These symbols are safe to redirect
to the external expf and logf symbols, because those names are always
reserved when single precision math functions are reserved and the
additional error handling code is either not reached or there will be
an error in the final result that will override an internal spurious
errno setting.

For consistency all of __ieee754_expf, __ieee754_logf and __ieee754_powf
are redirected using a macro.

88cfcda06b cygwin: unlink: workaround NFS non-ability to move file in certain cases
Under some not quite clear conditions, NFS fails to use its
unlink workaround to rename a file to ".nfsXYZ".  The problem has been
reproduced with the GAWK testext.awk testcase.  To workaround this in
Cygwin, we now call try_to_bin on NFS, too.  For some reason NFS doesn't
fail to rename the .cygXYZ file to .nfsXYZ after this Cygwin rename.
Fix comment in unlink_nt accordingly.

c156098271 New expf, exp2f, logf, log2f and powf implementations
Based on code from https://github.com/ARM-software/optimized-routines/

This patch adds a highly optimized generic implementation of expf,
exp2f, logf, log2f and powf.  The new functions are not only
faster (6x for powf!), but are also smaller and more accurate.
In order to achieve this, the algorithm uses double precision
arithmetic for accuracy, avoids divisions and uses small table
lookups to minimize the polynomials.  Special cases are handled
inline to avoid the unnecessary overhead of wrapper functions and
set errno to POSIX requirements.

The new functions are added under newlib/libm/common, but the old
implementations are kept (in newlib/libm/math) for non-IEEE or
pre-C99 systems.  Targets can enable the new math code by defining
__OBSOLETE_MATH_DEFAULT to 0 in newlib/libc/include/machine/ieeefp.h,
users can override the default by defining __OBSOLETE_MATH.
Currently the new code is enabled for AArch64 and AArch32 with VFP.
Targets with a single precision FPU may still prefer the old
implementation.

libm.a size changes:
arm: -1692
arm/thumb/v7-a/nofp: -878
arm/thumb/v7-a+fp/hard: -864
arm/thumb/v7-a+fp/softfp: -908
