* 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.

- 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.

(get_posix_access): Add handling for just created files requiring
their first Cygwin ACL. Fix new_style recognition. Handle SGID
bit. For old-style ACLs, ignore SYSTEM and Administrators when
computing the {DEF_}CLASS_OBJ perms.
* security.cc (get_file_sd): Revamp comment. Change and (hopefully)
speed up inheritance processing for just created files.
(alloc_sd): Remove.
(set_security_attribute): Call set_posix_access instead of alloc_sd.
(get_object_attribute): Fix return value.
(create_object_sd_from_attribute): Call set_posix_access instead of
alloc_sd.
(set_file_attribute): Remove.
(set_created_file_access): New function implemented in terms of
get_posix_access/set_posix_access.
* security.h (set_file_attribute): Remove prototype.
(set_created_file_access): Add prototype.
(searchace): Ditto.
(set_posix_access): Ditto.
* syscalls.cc (open): Call open_with_arch with mode not umasked.
* sec_acl.cc: Change preceeding comment explaining new-style ACLs.
Describe how to generate deny ACEs in more detail. Accommodate the
fact that a NULL deny ACE is used for {DEF_}CLASS_OBJ, rather than
a special Cygwin ACE. Improve further comments.
(CYG_ACE_NEW_STYLE): Define.
(get_posix_access): Change from Cygwin ACE to NULL deny ACE. Fix
CLASS_OBJ handling to generate CLASS_OBJ and DEF_CLASS_OBJ from a single
NULL deny ACE if the inheritance flags say so.
* sec_helper.cc (well_known_cygwin_sid): Remove.
* security.h (well_known_cygwin_sid): Drop declaration.
* sec_acl.cc (CYG_ACE_ISBITS_TO_WIN): Fix typo.
(get_posix_access): Rename index variable from i to idx. Define only
once at top level.
* security.cc (add_access_allowed_ace): Drop unused parameter "offset".
Accommodate throughout.
(add_access_denied_ace): Ditto.
* sec_acl.cc: Accommodate above change throughout.
* security.h (add_access_allowed_ace): Adjust prototype to above change.
(add_access_denied_ace): Ditto.
* sec_acl.cc (get_posix_access): Handle multiple ACEs for the
owner and primary group of the file. Handle the default primary
group ACE as DEF_GROUP_OBJ entry if the directory has the S_ISGID bit
set. Add comments. Minor code rearrangements.
Preliminary read side implementation of new permission handling.
* acl.h (MAX_ACL_ENTRIES): Raise to 2730. Add comment to explain.
* sec_acl.cc: Add leading comment to explain new ACL style.
Add definitions and macros to use for bits in new Cygwin ACL.
(DENY_RWX): New mask value for all temporary deny bits.
(getace): Add bool parameter to decide when leaving all bits intact,
rather than filtering them per the already set bits.
(get_posix_access): New function, taking over functionality to read
POSIX ACL from SECURITY_DESCRIPTOR.
(getacl): Just call get_posix_access.
* sec_helper.cc (well_known_cygwin_sid): Define.
* security.cc (get_attribute_from_acl): Remove.
(get_info_from_sd): Remove.
(get_reg_sd): Call get_posix_access instead of get_info_from_sd.
(get_file_attribute): Ditto.
(get_object_attribute): Ditto.
* security.h (well_known_cygwin_sid): Declare.
(get_posix_access): Add prototype.
* Throughout, use simpler ACE macros from Windows' accctrl.h.
* getfacl.c (main): Special-case SYSTEM and Admins group. Add comments.
* setfacl.c: Align more to Linux tool.
(delacl): New function to delete acl entries only.
(modacl): Drop delete functionality. Add handling of recomputing the
mask and default mask values.
(delallacl): Rename from delacl.
(setfacl): Call delacl in Delete case. Call delallacl in DeleteAll
and DeleteDef case.
(usage): Accommodate new options. Rearrange and rephrase slightly.
(longopts): Emit 'x' in --delete case. Add --no-mask and --mask
options.
(opts): Add -x and -n options.
(main): Handle -d and -x the same. Handle -n and --mask options.
Drop handling for -r option.
* getfacl.c (usage): Align more closely to Linux version. Add new
options -c, -e, -E. Change formatting to accommodate longer options.
(longopts): Rename --noname to --numeric. Keep --noname for backward
compatibility. Add --omit-header, --all-effective and --no-effective
options.
(opts): Add -c, -e and -E option.
(main): Handle new -c, -e, and -E options.
