Use <cmdsynopsis> element markup in utils docbook documentation, rather
than some preformatted text inside <screen>.
(This didn't happen as part of 646745cb, when we first started using
refentry elements to make it possible to generate manpages)
This helps produce better looking manpages:
* uses bold (for command names) and italic (for replaceable items)
* different output formats inconsistently treat tabs inside <screen>
(so we have to be careful to not use them in that preformatted text)
Also clean up various issues:
* Replace '[OPTIONS]' with a real synopsis of the options
* Consistently use 'ITEM...' rather than 'ITEM1 [ITEM2...]' for an item
which should appear 1 or more times (cygcheck -f, getfacl, kill)
* Consistently document the '-h | -V' invocation form
* Since replaceable items are now marked up so they have some formatting
indicating they are replaceable, we can drop wrapping them in angle
brackets, as is done in some places
* Add missing '-W' and '-p PID' options to ps synopsis
* Adjust cygpath synopsis to show that only one 'System information'
option is allowed, possibly modified by -A
Future work:
* Sync up the actual help emitted by the util, where it's been improved
* Also don't use <screen> for formatting 'OPTIONS' section of manpage
* pldd inconsistently uses '-?' rather than '-h'!
* Drop duplicate 'Options:' headers (mkgroup, mkpassword)
* Add missing indication that MACHINE is optional with -L (mkgroup, mkpassword)
* Tweak some <refpurpose> which try to be a synopsis, rather than a decription (passwd, ssp)
* Drop some stray '\n' in setfacl options
* Move 'Original Author' note in ssp to an AUTHORS section
* Use <para> to improve formatting of tzset manpage
The C standard says that errno may acquire the value ERANGE if the
result from strtod underflows. According to IEEE 754, underflow occurs
whenever the value cannot be represented in normalized form.
Newlib is inconsistent in this, setting errno to ERANGE only if the
value underflows to zero, but not for denorm values, and never for hex
format floats.
This patch attempts to consistently set errno to ERANGE for all
'underflow' conditions, which is to say all values which are not
exactly zero and which cannot be represented in normalized form.
This matches glibc behavior, as well as the Linux, Mac OS X, OpenBSD,
FreeBSD and SunOS strtod man pages.

xterm 368 and mintty 3.5.1 implement a new feature to support
notification of terminal scaling via font zooming also if the terminal
text dimensions (rows/columns) stay unchanged, using
ioctl(TIOCSWINSZ), raising SIGWINCH;
this patches cygwin to support that scenario
The new GetFinalPathNameW handling for native symlinks in inner path
components is disabled if caller doesn't want to follow symlinks, or
doesn't want to follow reparse points.
visium and iq2000 have libgloss configure bits that reference
target_makefile_frag, but it's never set. This leads to failures during the
configure process and an empty libgloss/<target>/Makefile. Naturally bad
things happen with an empty Makefile.
This patch initializes target_makefile_frag for both targets in their
configure.in files and updates the generated configure files. This fixes the
build failures. I've been using it in my tester for about a week and both
targets have flipped from consistently failing to consistently passing.
* libgloss/visium/configure.in (target_makefile_frag): Define.
* libgloss/visium/configure: Regenerated.
* libgloss/iq2000/configure.in (target_makefile_frag): Define.
* libgloss/iq2000/configure: Regenerated.
The scanf code was skipping the '0' after the 'x' causing the
resulting buffer to contain an invalid number when passed to strtod.

Binutils LD default linker script was recently fixed to allow memory
sizes to be set via command line. Use this feature to remove the special
sim linker script in libgloss.
It is acceptable to require newer Binutils version here because simulator
target is only used for regression testing the toolchain. Real HW
targets are not affected.

- compiler is sometimes optimizing out the rounding check in
e_sqrt.c and ef_sqrt.c which uses two constants to create
an inexact operation
- there is a similar constant operation in s_tanh.c/sf_tanh.c
- make the one and tiny constants volatile to stop this
Newlib for aarch64 uses libgloss for the backend. One common libgloss
implementation is the 'rdimon' implementation, which uses the Arm
Semihosting protocol. In order to support a remote host that runs on
Windows we need to know whether a file is to be opened in binary or
text mode. That means that we need to preserve this information via
O_BINARY until we know what the libgloss binding will be.
This patch simply copies the arm implementation from sys/arm/sys and
puts it in machine/aarch64/sys, because we don't have a 'sys' subtree
on aarch64.
The check for a file or dir within /dev/mqueue is accidentally using
the incoming path, which could be a relative path. Make sure to
restore the absolute POSIX path in path_copy and only then test the
path.
Also, move the actual check for a valid path below /dev/mqueue into
the fhandler_mqueue class.

/dev has been handled as virtual dir in cwdstuff, thus not allowing
to start native apps from /dev as CWD, even if /dev actually exists
on disk. Unfortunately this also affects Cygwin executables started
from a debugger.
When chdir'ing to /dev, check if /dev exists on disk. If so, treat
it as any other existing path.

The mq_open call is just a framework now. This patch moves the
entire functionality into fhandler_mqueue. To support standard
OS calls (as on Linux), make fhandler_mqueue a derived class from
fhandler_disk_file and keep the base handle the handle to the
default stream, to allow implementing O_PATH functionlaity as well
as reading from the file and NOT reading binary message queue data.
Implement a standard fhandler_mqueue::open method, allowing, for
instance, to touch a file under /dev/mqueue and if it doesn't exist,
to create a message queue file.
FIXME: This introduces a BAD HACK into path_conv::check, which needs
reviewing.
Keep the posix path intact in the fhandler, and change get_proc_fd_name
accordingly to return only the basename plus leading slash for
/proc/<PID>/fd.

The default PSAPI_VERSION is controlled by WIN32_WINNT, which we set to
0x0a00 when building ldd, which gets PSAPI_VERSION=2.
This causes K32GetModuleFileNameEx to be used for GetModuleFileNameEx,
which isn't available on Windows Vista.
Define PSAPI_VERSION as 1 for the built executable to work on Windows
Vista.
