Johannes Schindelin fb71716d2c Introduce the 'usertemp' filesystem type
* mount.cc (mount_info::from_fstab_line): Support mounting the current
	user's temp folder as /tmp/.  This is particularly useful a feature
	when Cygwin's own files are write-protected.

	* pathnames.xml: document the new usertemp file system type

Detailed explanation:

In the context of Windows, there is a per-user directory for temporary
files, by default specified via the environment variable %TEMP%. Let's
allow to use that directory for our /tmp/ directory.

With this patch, we introduce the special filesystem type "usertemp":
By specifying

	none /tmp usertemp binary,posix=0 0 0

in /etc/fstab, the /tmp/ directory gets auto-mounted to the directory
specified by the %TEMP% variable.

This feature comes handy in particularly in scenarios where the
administrator might want to write-protect the entire Cygwin directory
yet still needs to allow users to write into the /tmp/ directory.
This is the case in the context of Git for Windows, where the
Cygwin (MSys2) root directory lives inside C:\Program Files and hence
/tmp/ would not be writable otherwise.

Corinna Vinschen bc444e5aa4 Reapply POSIX ACL changes.
- New, unified implementation of POSIX permission and ACL handling.  The
    new ACLs now store the POSIX ACL MASK/CLASS_OBJ permission mask, and
    they allow to inherit the S_ISGID bit.  ACL inheritance now really
    works as desired, in a limited, but theoretically equivalent fashion
    even for non-Cygwin processes.

    To accommodate Windows default ACLs, the new code ignores SYSTEM and
    Administrators group permissions when computing the MASK/CLASS_OBJ
    permission mask on old ACLs, and it doesn't deny access to SYSTEM and
    Administrators group based on the value of MASK/CLASS_OBJ when
    creating the new ACLs.

    The new code now handles the S_ISGID bit on directories as on Linux:
    Setting S_ISGID on a directory causes new files and subdirs created
    within to inherit its group, rather than the primary group of the user
    who created the file.  This only works for files and directories
    created by Cygwin processes.

Jon TURNEY 383ff5fc47 Try to make sure struct _mcontext is 16-byte aligned
On x86_64, RtlCaptureContext() uses fxsave to save FPU/MMX/SSE state.

fxsave requires that the destination address is 16-byte aligned, or it will
fault.

CONTEXT is already annotated __attribute__ ((aligned (16))), do the same with
struct _mcontext.

Rearrange ucontext_t so that it's struct _mcontext element is also correctly
aligned.

Eric Blake 9067d19b9a headers: properly decorate attributes
As pointed out here:
https://cygwin.com/ml/cygwin/2014-07/msg00371.html

any use of __attribute__ in a header that can be included by a user
should be namespace-safe, by decorating the attribute arguments with __
(while gcc does a lousy job at documenting it, ALL attributes have a __
counterpart, precisely so that public headers can use attributes without
risk of collision with macros belonging to user namespace).

* include/pthread.h: Decorate attribute names with __, for
namespace safety.
* include/cygwin/core_dump.h: Likewise.
* include/cygwin/cygwin_dll.h: Likewise.
* include/sys/cygwin.h: Likewise.
* include/sys/strace.h: Likewise.
