Cygwin_props have been invented to allow switching off the unique
installation keys in the first place, supposedly for debugging.
This never really was a good idea, after all we *want* the installations
to be independent and there's no good reason to break that, not even
for debugging purposes.
Other than that, cygwin_props were meant to be used for some other global
settings which never took place. There's just no good reason to tweak
the DLL binary invisibly where a setting could be done in a file or the
environment.
This patch removes the cygwin_props entirely, including the related
settings in cygcheck.

* cygprops.h: Remove file.
* globals.cc (cygwin_props): Remove.

* 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.

A user of MSYS2 had non-deterministic segfaults when running simple
command from bash started from cmd. We've isolated the cause to
`C:\Program Files (x86)\Forefront TMG Client\FwcWsp64.dll`. See
<http://sourceforge.net/p/msys2/tickets/212/> for a little more
information.
It seems enough to include the software in BLODA, but if not, sorry for
the unsolicited patch and let's discuss.

- 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.

Fedora installs docbook2texi under the name db2x_docbook2texi
Other distros and Cygwin install docbook2texi under the name docbook2x-texi
Add a configure test to find either.
2015-07-05 Jon Turney <jon.turney@dronecode.org.uk>
* configure.ac: Add check for DOCBOOK2XTEXI
* configure: Regenerate.
* Makefile.in (DOCBOOK2XTEXI): Use.

* miscfuncs.cc (struct pthread_wrapper_arg): Add member guardsize.
(pthread_wrapper): Set thread stack guarantee according to guardsize.
Tweak assembler code so that $rax/$eax is not required by GCC to
prepare the wrapper_arg value.
(CygwinCreateThread): Fix deadzone handling. Drop setting a "POSIX"
guardpage (aka page w/ PAGE_NOACCESS). Always use Windows guard
pages instead. On post-XP systems (providing SetThreadStackGuarantee)
always set up stack Windows like with reserved/commited areas and
movable guard pages. Only on XP set up stack fully commited if the
guardpage size is not the default system guardpage size.
Fill out pthread_wrapper_arg::guardsize. Improve comments.
* resource.cc: Implement RSTACK_LIMIT Linux-like.
(DEFAULT_STACKSIZE): New macro.
(DEFAULT_STACKGUARD): Ditto.
(rlimit_stack_guard): New muto.
(rlimit_stack): New global variable holding current RSTACK_LIMIT values.
(__set_rlimit_stack): Set rlimit_stack under lock.
(__get_rlimit_stack): Initialize rlimit_stack from executable header
and return rlimit_stack values under lock.
(get_rlimit_stack): Filtering function to return useful default
stacksize from rlimit_stack.rlim_cur value.
(getrlimit): Call __get_rlimit_stack in RLIMIT_STACK case.
(setrlimit): Call __set_rlimit_stack in RLIMIT_STACK case.
* thread.cc (pthread::create): Fetch default stacksize calling
get_rlimit_stack.
(pthread_attr::pthread_attr): Fetch default guardsize calling
wincap.def_guard_page_size.
(pthread_attr_getstacksize): Fetch default stacksize calling
get_rlimit_stack.
* thread.h (PTHREAD_DEFAULT_STACKSIZE): Remove.
(PTHREAD_DEFAULT_GUARDSIZE): Remove.
(get_rlimit_stack): Declare.

Update list of pre-requisites, everything else is obsolete.
Future work: Ensure that the list of pre-requisites in FAQ 6.21 "How do I build
Cygwin" remains synchronized with this list.
