Improve case-insensitive checks (Bug#24441)

to avoid giving too much platform-specific information that
may not be accurate anyway.
* src/fileio.c (file_name_case_insensitive_p): Use pathconf with
_PC_CASE_SENSITIVE if _PC_CASE_INSENSITIVE is not available.
Otherwise if one approach fails (e.g., with errno == EINVAL), fall
back on an alternative rather than returning false.  Try skipping
the Darwin code, as it (1) no longer seems to be needed and (2)
does not seem to match the Apple documentation.  Leave in two
alternatives conditionally compiled based on
DARWIN_OS_CASE_SENSITIVE_FIXME in case (1) or (2) is incorrect.

* lisp/net/shr.el (shr-tag-table): Avoid duplication of images.

* lisp/international/mule.el (auto-coding-alist-lookup):
* lisp/files.el (file-truename):
(abbreviate-file-name, set-auto-mode, file-relative-name):
* package.el (package-untar-buffer): Use

Port --enable-gcc-warnings to Ubuntu 16.10

* src/gmalloc.c: Include <stdlib.h>, so it declares
hybrid_aligned_alloc (the definiens of the aligned_alloc macro),
so that GCC doesn't complain that hybrid_aligned_alloc is
defined without being declared.

Silence tramp warning

* lisp/net/tramp.el (tramp-file-name-for-operation): Add
'file-name-case-insensitive-p' as a known file primitive.

(Ffile_name_case_insensitive_p):  New functions.

FILE argument is on a case-insensitive filesystem.  (Bug#24441)

* lisp/dired-aux.el (dired-do-create-files): Use
'file-name-case-insensitive-p' instead of 'system-type' to check

'file-name-case-insensitive-p'.

Unbreak the build on Cygwin

Update chart.el

* lisp/emacs-lisp/chart.el (chart-mode): Derive from special-mode.

fixed number of newlines, use window-height.
(chart-bar):
(chart-trim): Use dolist.
(chart-file-count): The previous implementation was buggy and missed
extensions.  Use file-name-extension instead to detect file extensions.
Also use dolist and cl-incf to reduce verbosity.

* lisp/net/shr.el (shr--preferred-image): Add CR to whitespace regexps.
(shr-collect-extra-strings-in-table):
Render extra tables in an invalid html as well.

Resurrect 'memory-limit' on MS-Windows

* nt/mingw-cfg.site (ac_cv_func_sbrk): Set to "yes", otherwise
'memory-limit' will produce a trivial and useless result on Windows.

Update quickurl.el

* lisp/net/quickurl.el (quickurl-format-function):
(quickurl-sort-function): Use named function.
(quickurl-list-mode-map): Remove lines that are extraneous now that the
parent mode is special-mode.
(quickurl-format-url, quickurl-sort-urls): New functions.
(quickurl-read, quickurl): Use defun, as no cl-defun feature appears to
be used.
(quickurl-list-mode): Derive from special-mode.  Nix setting
buffer-read-only: special-mode does that.
(quickurl-list-populate-buffer): Use dolist instead.
(quickurl-list-quit): Use quit-window.  It looks like this was written
before the quit-window rewrite.  quit-window is very useful now.

Refine multi-hop specs in Tramp

* lisp/net/tramp.el (tramp-tramp-file-p): Suppress "/:" and "/c:".

* test/lisp/net/tramp-tests.el

Avoid infloop in python

Fix bug#24905

`_' to shut up the byte compiler.
(sha1-maximum-internal-length, smtpmail-smtp-server)
(smtpmail-smtp-service): add missing defvars

Fix Bug#24889

* lisp/net/tramp.el (tramp-file-name-regexp): Make it a
defvar.  Fix docstring.
(tramp-completion-file-name-handler-alist): Fix docstring.
(tramp-register-file-name-handlers): Reassign
`tramp-file-name-regexp' to the car of
`tramp-file-name-structure'.  (Bug#24889)

Port to FreeBSD 11 AMD

Problem reported by Ashish Shukla (Bug#24892).  I tested
this on FreeBSD 11 x86-64 with HAVE_SBRK manually undefined.
* configure.ac (system_malloc): Set to 'yes' if there is no sbrk.
(sbrk): Check whether it exists.
* src/alloc.c (my_heap_start) [!GNU_LINUX]:
Do not define, since this function is now used only on GNU/Linux,
and sbrk might not exist on other platforms.
(malloc_initialize_hook) [!GNU_LINUX]:
Do not call my_heap_start, since its side effect will never be used.
(Fmemory_limit) [!HAVE_SBRK]: Do not call sbrk.
* src/unexelf.c (unexec) [!HAVE_SBRK]: Assume that nothing like
sbrk exists.

Port emacsclient to FreeBSD 11 etc.

* lib-src/emacsclient.c: Include <string.h>.  This is needed on
platforms like FreeBSD 11 that use code involving strlen etc., and
because <config.h> no longer includes string.h.

Prescribe history for read-regexp in query-replace

In the fix for bug#24580, the history argument for read-regexp was
removed erroneously; read-regexp's history argument defaults to
regexp-history, not minibuffer-history.
* lisp/replace.el (query-replace-read-from): Tell read-regexp to use
minibuffer-history.  Fixes bug#24873.

previously changed whitespace-style globally.  Fix this, and use
whitespace-active-style, to take account of any changes the user may
have made.  Simplify the documentation: the force parameter simply
forces all classes of whitespace problem to be considered.
(Bug#24745)

Document use of `tab-width'

* lisp/whitespace.el: When talking about `8 or more spaces', mention

* lisp/whitespace.el (whitespace-report-region): Make it respect
whitespace-style, including any additions made by the force parameter.

* lisp/whitespace.el (whitespace-space-after-tab-regexp)
(whitespace-regexp): Match all the spaces after tabs for highlighting,
not just the first tab-width.  Fix whitespace-space-after-tab::space

(Bug#24745)

Remove duplicate documentation

Revert "Disable bracketed paste in a terminal in char mode"

This change causes regressions, and besides, disabling BPM frame-wide

python.el: Fix detection of native completion in Python 3 (bug #24401)

With Python 3.5, (python-shell-completion-native-get-completions ... "")
would return an empty list, causing python.el to think that native
completion was unavailable (the difference between Python 2 and Python 3
is due to https://bugs.python.org/issue25660).

* lisp/progmodes/python.el (python-shell-completion-native-try): Use "_"
