fix tty_nr maj/min bits, vmmaxrss units, and x86 format mismatch:
ctty maj is 31:16, min is 15:0; tty_nr s/b maj 15:8, min 31:20, 7:0;
vmmaxrss s/b bytes not pages;
times all 64 bit - change formats of first two instances from %lu to %U;
realign sprintf formats and variables/values in more logical groups
- Previously, script command sometimes crashes by Ctrl-C in Win 7
if it is running in console, and non-cygwin app is foreground.
This patch fixes the issue.
- The recent commit "Cygwin: pty: Fix timing of creating invisible
console." breaks the feature added by commit 72770148, which
prevents pty from changing code page of parent console. This patch
restores that.
- Previously, invisible console was created in fixup_after_exec().
However, actually this should be done in fixup_after_fork(). this
patch fixes the issue.
- When temporarily attaching a console, the timing of acquiring
attach_mutex was not appropriate. This sometimes caused master
forwarding thread to crash on Ctrl-C in Windows 7. This patch
fixes the issue.
../newlib/libc/libc.xml:22242: element refentry: validity error : ID iconv already defined
<refentry id="iconv">
Use a separate namespace for chaper ids, to avoid collision between the
ids for the chapter and function 'iconv', now that iconv documentation
is generated unconditionally.
Unless make is invoked with V=1, have xmlto pass the parameter
'man.output.quietly=1' to xsltproc to suppress "Note: Writing foo.N"
output from the manpages stylesheet.
(This doesn't quite do what it says: The output is not silenced if V has
any value, including 0. You could consider that either a bug or a
feature.)
Simplify rules for creating docbook XML used to create manpages:
Updating the output using move-if-change and then unconditionally
touching the .stamp file doesn't make much sense.

Remove the pointer indirection through the read-only _global_impure_ptr and
directly use a externally visible _impure_data object of type struct _reent.
This enables the static initialization of global data structures in a follow up
patch. In addition, we get rid of a machine-specific file.
By including sys/_stdint.h, all types from stdint.h are
exposed even if stdint.h isn't pulled in explicitely. Include
<machine/_default_types.h instead. Fix up newlib and Cygwin
files which rely on stdint.h types, too.

Even after fork, we might need the parent sigmask without having
access to the real _main_tls. There's a short time at process startup,
when _main_tls points to the system-allocated stack, but wait_sig is
already running. If we can't lock _main_tls, because find_tls can't
find it yet, we now access the parent's sigmask via child_info.

The x86_64 thread stack area collides with the share user data in
recent versions of Windows. Let's get ourselvels get out of the
way and move the thread stack area in the former slack space
between DLL area and heap, from 0x6:00000000 to 0x8:00000000.
That quadruplicates the stack area, so allow bigger maximum stack
sizes.

The _open() C function is declared as having variable arguments in
newlib, so second and third arguments are passed on stack. Add code to
move them into registers, since that's where the PRU simulator expects
them.
Issue was exposed by the GCC test gcc.c-torture/execute/fprintf-2.c,
which relies on tmpnam implementation to pass correct flags to _open.

A recent patch fixed gmondump to stop printing "0x0x" as an address
prefix. It turns out the Cygwin User's Guide and the gmondump and
ssp man pages (all from utils.xml) have examples of the same error.
- In the latest GDB (11.2-1), Ctrl-C behaviour is broken a bit for
non-cygwin inferior. For example, Ctrl-C on GDB prompt is not sent
to GDB but to the inferior. This patch fixes the issue.
- The internal handles in HPCON should not be inheritable, however,
the current code duplicates them as inheritable when handing over
ownership of the pseudo console. This patch fixes the issue.

- Currently, close_pseudoconsole() is called unconditionally from
fhandler_termios::process_sigs() on Ctrl-C. This causes deadlock
if Ctrl-C is pressed while setup_pseudoconsole() is called. With
this patch, close_pseudoconsole() is called only if the master
process is the owner of the nat-pipe to avoid the deadlock.
- from Brian Inglis <Brian.Inglis@systematicsw.ab.ca>
- add support to _tzset_unlocked_r() to support quoting std and dst
names with angle brackets <> as per Posix
- modify documentation of tzset.c
- As mentioned in commit message of the commit b531d6b0, if multiple
writers including non-cygwin app exist, the non-cygwin app cannot
detect pipe closure on the read side when the pipe is created by
system account or the the pipe creator is running as service.
This is because query_hdl which is held in write side also is a
read end of the pipe, so the pipe is still alive for the non-cygwin
app even after the reader is closed.
To avoid this problem, this patch lets all processes in the same
process group close query_hdl using newly introduced internal signal
__SIGNONCYGCHLD when non-cygwin app is started.

This fixes a bug introduced in a previous patch (Commit 44b60f0c:
Make __sdidinit unused). Removed intitialization of __cleanup from
__smakebuf_r(). All callers of __smakebuf_r() call __sinit()
through the_CHECK_INIT macro, thus __cleanup is already
initialized. This fix also allows _cleanup_r() to be made static.
Changed its name to cleanup_stdio() and removed its declaration
from local.h.
Rename __sfmoreglue() in sfmoreglue() and make it static. This function is
only used by __sfp() in the same translation unit.
Remove use of register keyword.
[PATCH] newlib: Only call _fputwc_r if ELIX_LEVEL >= 4
(nano-)vfprintf.c is enabled for ELIX_LEVEL >= 1. When _WIDE_ORIENT
is set, its __sprint_r / __sfputs_r functions unconditionally called
_fputwc_r which is only in ELEX_LEVEL >= 4. With this commit,
the _WIDE support in (nano-)vfprintf.c is disabled for ELEX_LEVEL < 4.
This code has not been updated since 2016, and it looks like it has
rotted quite a bit since. It does not build against the current set
of phoenix sources -- I had to hack both the kernel headers and the
newlib headers up to get it to build, and I still have no idea if it
actually links or runs. It seems like the project itself has moved
away from newlib and to its own C library:
https://phoenix-rtos.com/documentation/libc/README.md
So since there's no interest from the phoenix folks to maintain this,
and it has a significant amount of non-standard code that we try to
keep up-to-date (without actually testing it), just punt it all.
The recent makefile reorganization broke the amdgcn port by creating
duplicate __malloc_lock symbols. This patch fixes the problem by renaming
the malloc_support.c file to mlock.c, thus overriding the default symbol
properly. Actually, I'm not sure how this ever worked?
I've had this lying around for probably a year or two at this point.
It just changes all the instance of "errno" from a common symbol to an
extern. I can't offhand recall where the actual definition is, but it
certainly exists in the generic code.
