mknod[at](): moves from unistd.h to sys/stat.h

* this solves #10883.

Updated copyright in headers. No functional change.

Updated posix headers to remove commas from copyright line, to match the preferred coding guidelines.
Cleaned up some header style violations, making sure there are two blank lines after the header guards.
This fixes the posix header part of #2191.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39288 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added missing AT_EACCESS.
* Implemented renameat(), faccessat(), fchownat(), fchmodat(), and mkfifoat().
* Added stub for mknodat().
* The kernel backend for faccessat() does not yet differentiate between
effective and real user/group IDs, though.
* Removed B_ENABLE_INCOMPLETE_POSIX_AT_SUPPORT, as we now support everything
(more or less). This also closes ticket #4928.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34288 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Introduced new header directory "config", which ATM contains HaikuConfig.h
and types.h. The idea is to provide a basic architecture/compiler
abstraction by defining types and macros that allow the posix/ and os/
headers to be mostly architecture/compiler agnostic.
* Adjusted the posix/ and os/ headers accordingly.
* <SupportDefs.h>: Introduced B_PRI* and B_SCN* macros similar to the PRI*
and SCN* macros defined in <inttypes.h>, just for the BeOS/Haiku [u]int*
types and some POSIX types (e.g. off_t, dev_t, ino_t) that don't have POSIX
macros. Also the B_PRI* and B_SCN* macros are available unconditionally,
unlike the <inttypes.h> macros, which require __STDC_FORMAT_MACROS to be
defined in C++ mode.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34214 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented POSIX.1-2008 functions unlinkat(), symlinkat(), mkdirat(),
utimensat(), and futimens().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34010 a95241bf-73f2-0310-859d-f6bbb57e9c96

Moved the POSIX *at() functions and AT_* macros out of the default namespace
as long as the full set hasn't been implemented. They are guarded by the
B_ENABLE_INCOMPLETE_POSIX_AT_SUPPORT macro until then. Fixes the build.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33990 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added AT_SYMLINK_[NO]FOLLOW constants and fstatat(). Fixes the findutils
gnulib build.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33987 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Made our struct stat POSIX compliant again -- the time_t fields have been
replaced by timespec fields. Via macros the structure is still source
compatible with the old one.
* Introduced header <compat/sys/stat.h> that defines the old stat structure
(as stat_beos) and conversion functions
* Introduced versions for [l,f]stat().
* Added symbol versions for BDirectory::GetStatFor() for sake of binary
compatibility.
* BStatable::GetStat(): Renamed the old method, changed its parameter to
stat_beos*, and and made it private. Added a new version (using up a
reserved vtable slot). It remains source and binary compatible.
* BRefFilter::Filter(): Changed the struct stat* parameter to struct stat_beos*
for sake of binary compatibility. This breaks source compatibility, though,
which we can't help, since the class doesn't have reserved vtable slots.
* Fixed several issues with the stat structure change, mostly adjusted uses of
BRefFilter.

* Threw away the broken stat() vs. _stat() mechanism to allow for more fields
in struct stat.
* Instead, I followed Marcus' great idea and added a compatibility check in
the runtime loader: now, R5 binaries (also shared libraries) are detected,
and they get special versions for stat(), fstat(), and lstat() that return
the smaller stat struct.
* However, I've disabled (in src/system/libroot/posix/sys/stat.c) using the
larger stat field for now, as this breaks some of our optional packages.
So until we rebuild them all, this shouldn't be enabled.
* This should now also be used for BeOS compatibility in libnetwork.so.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27961 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added stat::st_blocks field as required by POSIX. This also closes ticket
#2261.
* Made at least BFS report it more or less correctly (the attributes are
ignored, though).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27791 a95241bf-73f2-0310-859d-f6bbb57e9c96

* As pointed out by Andreas, the previous patch wasn't really correct; ALLPERMS
should really contain all permission bits.
* It now uses S_ISVTX instead of S_ISTXT - this is how it works in Linux as
well, while FreeBSD uses S_ISTXT there (but S_ISTXT and S_ISVTX have the
same value there, too).
* Also fixed the fs_shell this time.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26761 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Patch by Andreas Färber: remove undefined S_ISTXT from ALLPERMS.
* This fixes bug #2560.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26754 a95241bf-73f2-0310-859d-f6bbb57e9c96

Patch by Andreas Faerber:
Replaced single-line comments by multi-line comments for ANSI C
compliance.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25433 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added socket macros.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24881 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented flock() semantics to the advisory locking backend. Not tested
(must also compare to BSD; I've looked at their sources, but I might have
missed something).
* Added sys/file.h and the flock() system call.
* common_fcntl() could forget to put back the file descriptor on some error
conditions (I guess we should introduce and use a DescriptorGetter class).
* Cleaned up fcntl.h, moved the BSD extensions S_IREAD and S_IWRITE to
sys/stat.h where they belong, and added the missing S_IEXEC to them.
* Added some more comments.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23836 a95241bf-73f2-0310-859d-f6bbb57e9c96

Enabling the extended stat() versions had unforeseen consequences (broke the build,
src/bin/coreutils/src/cp.c, line 542 needs stat() exported), therefore, I disabled
it for now again.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17902 a95241bf-73f2-0310-859d-f6bbb57e9c96

* BEntry::GetStat() and BNode::GetStat() used sizeof(struct stat) for the kernel
syscall, but they could not know if R5 code called them (in which case the stat
size has a different size). We now always only return the R5 stat structure here.
This fixes bug #420. We might want to find a different solution to this problem,
though.
* Be got SYMLINK_MAX wrong - it's not the maximum number of links (that's SYMLOOP_MAX),
but the maximum size of a symlink buffer. Added missing SYMLOOP_MAX and SYMLINK_MAX
constants to limits.h.
* Fixes MAXSYMLINKS to use SYMLOOP_MAX, instead of SYMLINKS_MAX (which doesn't exist
in POSIX specs, but we (intentionally) break source compatibility here).
* Reenabled the Haiku versions of stat(), fstat(), and lstat() when build for Haiku.
* Removed OpenBeOS namespace stuff from the files I touched.
* Removed superfluous StorageDefs.Private.h, whyever that ended up in a public header
is beyond me.
* Cleanup.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7511 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixes POSIX and R5 compatibility of the stat structure; readded field st_rdev.
Added an additional field st_type and changed functions to allow for this
extension while maintaining R5 compatibility.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7495 a95241bf-73f2-0310-859d-f6bbb57e9c96

removed #include <OS.h>


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4206 a95241bf-73f2-0310-859d-f6bbb57e9c96

Some header work to make it more posix compliant.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3080 a95241bf-73f2-0310-859d-f6bbb57e9c96

Changed an unused field of struct stat (st_rdev) to st_type, so that we
can use this structure to call fstat() on attributes and indices.
Added more functions to the file system interface (attributes, and indices).
Added header fs_attr.h, and fs_index.h.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1158 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added a BeOS like fcntl.h, with some additions (which might be implemented
some day).
Cleaned up sys/stat.h a bit, and added new definitions for different types
of symlinks I plan to add - though I am still not sure if it's a good idea ;-)


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@580 a95241bf-73f2-0310-859d-f6bbb57e9c96

Big commit: Added symlink support to the kernel.
- added needed syscalls to access symlink support from userland
- implemented lstat(), symlink(), and readlink()
- added dev_t to ktypes.h (for now - should be in a public header anyway)
- added symlink support to the "ls" command (now calls lstat() and shows the
link target with the -l option)
- changed the sys_read_stat() call to support symlinks, and updated files
using that function (it gets an extra argument: bool traverseLink)


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@560 a95241bf-73f2-0310-859d-f6bbb57e9c96

This is the correct place for this file.
Improved the comments and doxygen style to try and make the file
more readable.

The previous version can't be removed until we have the posix paths included
in the include paths. Once this is done the existsing version should be
removed as this is more up to date.
